Jimmy Diresta here, / jimmydiresta l got this broken gas drill last year from youtuber hand tool rescue asking if l could get it to run, well we kinda got it but was still having problems, since then another youtuber sent a mini gen set that has the same engine, lets see what is wrong by taking the both of them apart to see what was wrong on the drill.
I have a '78 Honda Goldwing with a mechanical fuel pump that developed a crack in the rubber diaphragm (which is very similar to this diaphragm). Since all the check valves are on the wet side of the pump, I cut a new nitrile diaphragm and placed it on top of the old diaphragm (on the wet side). I used a new Nitrile glove (one of the blue ones) and used the palm area since that was just big enough without any stretching needed.
Works as it should now and it was one of those moments where I amazed myself. A very simple fix and even ten years later, no further problems.
Mini footnotes on the generator:
It produces 300 watts of power at full load, some say 350 but 300 is their sweet spot before damaging the generator.
It has a 12v hookup via wingnuts at the back. It creates up to 12amps according to the manual.
12v hookup and 120v plug can be used both simultaneously as long as it wont overload the system. DO NOT REVERSE THE POLARITY OF THE 12V CONNECTION OR DAMAGE WILL OCCUR!
The diodes will blow, and the generator will be compromised.
Adjusting the fuel mix and governor is to be set after the engine warms up and the specified load is applied. There will never be a set adjustment, only adjustment will be set by ear (running smoothly). Off load running will be high or choppy and stated it is normal. Dont touch it unless a different load is made.
There is no info on set RPM or Hertz since the adjustment is made by ear at their specified load of 250-300 watts. I'm sure it supposed to be 60hz, but judging the sound of engine, its definitely turning more than 3600rpm.
The carb fuel pump system utilizes a small port after the throttle butterfly. When it is closed, the pulses from the intake transfer through that internal port which goes through a series of chambers to the diaphragm. Then the check balls and the special check valve gasket does the one way fueling to the metering valve. Then it goes out to the hole before the butterfly.
This design is recreated on newer ryobi/ troybilt 4 cycle engines like their blower and trimmers. You'll notice their walbro carbs do NOT have a pulse hole like your generic carbs do to function the fuel pump. They get their pulse from the vaccuum of the intake after the butterfly ( or barrel on their walbro).
Only difference was on walbro 4 stroke, they have a spring on their diaphragm to push back after the absence of vaccuum.
Since this is a 2 stroke, ohlsson/rice carbs pulses with vac and blow so no spring was needed. It moves the diaphragm normally.....hence their compact and crude design.
They are inefficient on today's terms and definitely not EPA friendly but who cares, it is a badass rare little machine.
First of all, you are very welcome to show the story behind this generator :).
I'm so happy to see her on the spotlight. It was revving high since I set it that way, might be too high lol sowwie.
And the fuel mix was definitely lean since it was last set last summer here in Florida lol, again sowwie.
But I'm surprised it gave alot of pulls to start but I'm very happy to hear her properly.
EDIT* Now I see why, that diaphragm was terrible. I received it as is, the carb pieces are all original from my prior ownership. I just clean it and it ran so I left it alone.*
Awesome video as usual, enjoy your newly acquired piece of history. I made sure at least the spark was there, I cleaned/adjusted the points as per spec on the pullstart cover. And it did ran prior shipping but....again Florida setting lol.
PS: 40:1 is very, very lean. They LOVE and NEED oil. 25:1 is good. If you dont see oil out the exhaust, it is not enough lol.
EDIT #2: @Mustie1, I totally forgot one special info. I forgot to send you a set of leads to the alligator clips. You see those two wingnuts at the end of the generator ?
That is for 12volts. It charges car batteries :) I have not tested that feature so put a meter on it prior.
Great job!!! :D
Alex
thank you again alex that was very nice of you and it made for great video.
@@mustie1 you are very welcome sir, keep on wrenching!
That is a cool little unit.
alexboi32 Yes, Thank you again for sending it to Mustie1. It was a great help to troubleshoot the drill engine! Very nice of you!
If you send it - It will run.
I was watching another channel and the guy said, “Like Mustie would say, ‘must be the carburetor.’”... Than I got your notice.... Made me smile....
Hi Mustie, If you find the material used for the gasket, get yourself a small laser cutter/engraver, this would allow you to cut your own complex gaskets. With regards rejuvenating the old gasket, try 303 Aerospace Protectant spray, soak it in that for a while, as it's designed for vinyls and rubber etc.
small engine will it run great start to a Sunday. thanks Sir HUGE THUMBS UP
Lol those aren't thumbs...there adjustable wrenches..😎 They we're obviously built to fix things
So nice a mustie1 video, warm bread and coffee.
The perfect Sunday. Life is good.
Yup! Watched him for a bit with a coffee. Did some errands took a nap and now another hot coffee to finish it up! Go pats!
Love that lil generator........drill also cool but that generator is pure history. Thanks for the guy who sent it to you :)
I feel mustie deserves the generator more than myself. After all his commitment to the community, and assist the repair of the drill, least I can do is provide a special gift.
It will basically sit on my garage pedestal, and nothing disturbs me more than an engine that works.....doesn't gets their exercise or serve their purpose.
Mustie will provide a better life for it and will bring in joy.........as long as it runs at least lol.
Your organizational skills are only surpassed by your problem solving ability! Thanks!
Hi Mustie I. I enjoy all the different things you do with the engine’s and the car’s and the way you bring your audience into your space keep doing what makes you happy as I can see your enjoying your channel.
I do Pat 🇦🇺. 👍

Mustie1 gives us the best Sunday entertainment, thank you for letting us be with you in your garage.
Way to go Mustie! Amazing patience and perseverance. Thank you for sharing.
Mustie...I have to say I really like your videos. I also want to tell you that if it was not for you I would have not been able to repair my snowblower. Your videos about how to work on the carb saved me a bunch of money!! Thanks for all the effort you put into your videos and how much fun they are to watch!! Keep up the great work!
thanks jaxon
You are an awesome fixer. I’ve learned so much from watching your lawnmower and snowblower videos. I only wish I have the opportunity in my garage to fix equipment like you do.
Seeing that gas drill brought back memories! Linemen use them to frame an inaccessible pole! I can tell you that gas drills are a mixed bag of emotions, sometimes. Ours never had the primer button, but they either want to work, or not at all! I kept a brace & bit handy, just in case!
Thanks for the memories!
I’m liking the little generator, great fix on both.
Saw fuel pump diaphragm material sold by the sheet on eBay. Thanks for the great videos mustie
I have a little nemesis myself, sits on the shelf above my bench.... a cute little very lightweight leaf blower with a 24 cc engine, fully rebuilt carb but only runs if bottle fed. It's annoying as hell but I just can't throw it away, yet.
I like the gray benchtop blanket. Nice touch.
never understood the first thing about motors but I keep watching and learning. Fascinating stuff . Thanks and ATB from Belgium - Marc
These are pretty cool little engines. Nice job Mustie!
My Dad worked for the local power company and they bought 3 of these which said “DRILLGINE” on them. They bought them for the linemen to use in bucket trucks. They never started so the guys did not use them. We wound up with one that was going to be scrapped. We got it working but you couldn’t depend on it. They thing was so small things were always going wrong with it. It was 2 cycle. I’d like to send you a picture of the go cart my dad built for me 52 years ago. Just needs cleanup and a throttle cable.
That's how hand power tools should be made - no faffing around for 16 hours while the battery charges up, or the battery dies four holes from the finish. Just fuel it up and you're away again in a minute! . . . Got to say, I do like that "Tiny Tiger" generator. I could just imagine that in the back of a pick-up, and spending a week in a mountain cabin, using it to power the lights, perhaps a radio, and finally, recharge the pick-up battery because we left the interior light on when we parked it!
We don't make things like we used to, that's for sure!
Screw the superbowl I'm watching this.. 👍
A much better use of your time :)
@@gregorythomas333 I agree 100%
It's the Super Floatbowl...
Your perseverance is admirable.
That's the cutest little gas-powered electric generator I've ever seen~!
Mustie, not sure if another one of the 486 commenters below mentioned this product for the rubber gasket. Rawn Re-Grip Rubber Cleaner & Revitalizer. Excellent product. Readily available on-line and not super expensive. A little bit goes a long way. Worth it for future projects, if you’re interested. Great work!
I would like to thank you sir for having in depth videos on small engines and motors helped me fix and determine if worth fixing some of my stuff thumbs up and thanks again
Thank you for finally getting this insane thing going! If we are ever all in the same room, we should probably ceremoniously burn this drill.
Even burnt Mustie would make it run again. ;)
Are you going to finish it?
I say we run over it with a forklift Mustie gets running!
Hand tool rescue or save the engine for a modeler to put back onto an old airplane. These things are just too cool to destroy maybe even in drill form if you feel that way lol
thanks again for sending it my way, l enjoyed the challenge
Get the raw diaphragm material from Mcmaster Carr and make a small run of carb kits for these carbs. Model airplane types would love you! Try the Silicone oil / spray to soften up the stiff old diaphragms. That was really good advice in those earlier comments!
Someone was really industrious with the idea of fitting a small aero-model engine on various implements, i see. Neat. I figured that the drill was a one-off deal (to be read, just that type of unit). I wonder what else has that running set on it if they did the generator.
My grandmother had a washing machine with an O&R engine!
love the label on the Tool Box "More Down Low"
I may never work on small engines like these (Famous last words), but the trouble shooting techniques that you use are critical to working in any gas engine. Spark, fuel, carburetor, and compression. Simple timesaving steps, like using a separate magnet bowl for each carburetor and trying to make a gasket are second nature to you, but foreign to me. Thanks for posting. I always learn from your videos
P.S. the Karmann Ghia looks marvelous
Boy, those two tested ya . . . . great patience and perseverance . . . . :) Rog
I have watched this drill travel the US. Now it works I want to see Diresta use it. Cheers
Hey mustie, Iv'e been feasting on your videos for about a week now, And i'm thoroughly enjoying them, And iv'e learned a lot along the way, And i now have the confidence to check the float bowl in my lawnmower for the first time in 30 years lol. You certainly know your way round an engine, Keep up the good work, All the best from scotland.
not too sure if you've ever heard of a place called McMaster-Carr? you mention in the video around 45 minutes how you said you wished they made the material in a bulk form. well mcmaster is a mechanics wet dream and they do in fact sell that stuff in sheets. i looked and found nitrile rubber sheets 1/32 thick that might fit this bill for around 15 bucks! mcmaster is always my first stop in a situation like this where you might have to fabricate a part. def worth a look at the very least i think you would appreciate a website like them!
I think that would be too thick. I'd probably order some nitrile nylon diaphragm sheets from ebay.
We use McMaster-Carr in aviation and other industry all the time. Best source for just about any material.
@@pekkasaarinen2902 maybe it would be, I was just making a suggestion as for a place for him to find a possible solution.
What about cutting up a protective gloves made of latex or nitrile? They come in several thicknesses..
@@kellerrobert80 I have used nitrile gloves to make a diaphragm for an old edger . Worked well for several years.
Edge of your seat entertainment for sure!! I was beginning to wonder though, but then I snapped out of it and remembered it was Mustie1! Well done sir!
I think that the problems we are witnessing with these is the main reason why the concept never caught on. There seems to be a limitation with engines of this size that corresponds to reliability, ease of use and the trouble with locomotion. Ferrying fuel along with this and the quirky nature made running electric to a location to power a conventional drill a no brainer. I appreciate the challenge and the effort to get it to go, but if we really needed something like this to work and we spent this much time and got it going for a little while and then went home and came back the next day and were back to square one, I think most of us would say screw it and buy a mile worth of extension cords.
That tiny tiger is the cutest source of electrons ever.
Over an hour of Mustie?! Didn’t we just have Christmas?!!
Had a pushrod seize in me. Cleaned and polished it up well and lubed it with 3n1. Got points working again. Love your vids man!
Very cool little engines they look unique.
Good job at troubleshooting all the issues on that little motor 👍 What a battle for such a tiny engine lol
i really like your videos. i also work on small engines in my spare time. thought i would share a tip. try using pensil earaser for cleaning electrcal connections. works great and dont remove any metal
You have the patience of a saint. It's always a joy to watch you beat entropy with dogged perseverance.
Best channel EVER! Thanks for the great start to my day! I am so happy you revisited the drill.
I have 2 of these, a generator and chainsaw. NEVER run them leaner that 24:1, that will kill them, even with modern 2 stroke oil. The 2 main problems with these engines are usually the carb diaphragm and crank seals, which is the issue with both of mine
Yeah, I've cut diaphragms and gaskets for similar carbs that generally work great. Tedious as hell. I used to have a gasket cutting/punching set but it got lost in a move. I was a Machinist Mate in the USN and we made a lot of our gaskets and diaphragms at sea (no parts store around the corner). A set of leather punches works pretty well, especially for small holes.
My son came up with one of those Tiny Tiger generators back when he was in high school. I don't think he ever got it running, something was broken. It is neat to see one running.
It's a miracle these condensers still work. The condenser is just a metal bodied capacitor. At one time, capacitors were known as condensers and the moniker has stuck in engines. Presumably they are ceramic or something.
Mustie has more patience than I do by a wide margin. I am re-watching his videos and must say that I much prefer the ones shot in his home garage. Seeing his collection in the background is great. I know that he needs the space in the new garage and the better lighting, etc. but much of the character is lost. In any event, Mustie 1 is great. Thanks 😊.
That little gen is cool.
Thanks for the sneak preview on Hand Tool Rescue. Yours and his are some of my favourite channels on TH-cam!
Back in the 80’s as I was restoring a ‘64 GTO, I found that DCM, Dichloromethane, would bring rubber back to almost new look and pliability. The fact my dad was a chemist allowed easy access to the DCM. I wouldn’t know how to get it now. What a great way to spend a Sunday morning.
Actually I did think you had forgotten the generator. But you didn't. Persistence payed off. Great video.
Try Pressure testing old two strokes to check the crank seals and gaskets.
Determination!!! Excellent work!!!
Well done sir ! Your perseverance paid off . I hate those little diaphragm thingy's !!
Outstanding. Two people (maybe more) couldn't get the drill going, but you did. :)
Glycerin - We used it to soften hardened rubber VCR belts & clutch wheels, back in the day. Used to be a pharmacy product.
Mustie 1 is a brilliant alchemist. I enjoy the videos immensely. Thanks a million.
Will they run ???...once they are in Musties workshop they will run, whether they want to or not, they will have no say in the matter...they wiil be made to run END OF ! :-)
I sure
First time I ever seen a primer, built like that. Great video mustie1 👍👍👍
Hi from the UK. Another great video Mustie1. I see the mice got to your jacket !!! :)
roconnor01 my guess is battery acid!
Well done sir...well done. I got a little edgy when you began disassembly of the "good" carb. But you pulled it all together. BRAVO !!
Thanks for letting me spend the afternoon in your shop. VWs model airplane engines and spilled gas on the bench, I'm a subscriber. Been watching for a while but today did it for me. Thanks
I love learning how to fix real problems from a real expert. Like an apprenticeship this is how people learned a trade before all these modern day schools. I spent a year learning about communications equipment but all I learned was how to tell when the equipment was working. My real training began when I was out in the field, at 2 in the morning, facing a real problem, costing the company three thousand an hour, under a time limit and with no one to help you. You find ways to get things working or you get out of the business.
You have an extra measure of patience, which my wife says I don’t have any, I am jealous.
Glad to see you revisit the drill and get it working!! Also that gen is pretty cool, especially with the 12v output.
You can buy the diaphragm material on Ebay coming from the UK. They have it in thicknesses of .3, .4, .5 mm. I can send you a link if you want.
l already ordered it thanks
@@mustie1 cool. Looking forward to the next video
...Grabbing that coil to start it.... Heh!
I'm glad it has no cracks or leakage, or you'd know it first pull!
Nice work Mustie, great video.
That drill looks like something Tim the Tool Man Taylor would have made :) Great work Mustie! Was a pleasure hanging out w/ya.
Those "challenges" puts my patience to the limit. Nice job Mustie !
2nd. Hi Mustie I. Thanks for the video. Pat 🇦🇺
"A little on the incontinent side" - LOL These small motors are a wonder.
Hey Mustie, Can I make a suggestion about that 'Fine Print' on that generator? My eyesight is HORRIBLE these days. I frequently use my Cell Phone camera to snap pictures and then BLOW up the picture to read the FINE PRINT. Works like a charm. I also use my phone to get into hard to reach places like the top of a fuel tank in a car to see what obstacles are in my way. and DON'T forget to turn on the flash for even better pictures!
Nice work! Those O&R's go for a mint price on ebay so they are very collectable!
I love small model engines especially early ones. That generator is so cool would be pretty fun to take camping or something if it ran reliably not sure how powerful it would be but still really cool, the drill on the other hand is long obsolete with cordless stuff coming so far. Its a neat piece of history nonetheless
Yet again, genius.. great vid mustie1. I thought i was the only one to go this far, i think you just topped me. Well done Brother.
You are so patient!congratulations
Great to see this epic collaboration resurrected.
Really liked that one. Learned a lot. ANd when you were searching if the small check valve was going after or before the gasket I was shooting on top!! Its pluging the smal hole!!! Damn I am sure they could hear me south of the border..
Cool little gen
It needs feet or something.
True
The flapper gasket goes against the main body of the carb... above the red gasket . The red gasket has a large hole cut out to allow the flap to open and close. The jet or passage is not letting it get enough fuel... might have a vacuum leak. use a can of WD or similar and spray the sealing surfaces. Listen for a change in idle..
That’s a bloody big model engine.
Thanks once more MUSTIE!
Rod
that is one cute generator
i would love to have one like that one day
I thought the little drill was dead for sure when you put it on the back burner. Great to see it live again after your wizardry.
Awesome Mustie! Thanks! 😊
I was trying to tell you that the plastic check valve was on the opposite side of the gasket on the good carb but you didn’t hear me. Lol
Great job on those antique two stroke engines Mustie, that drill seems to run good with the homemade diaphragm you made, keep up the good work!
Hi Muskie1, I enjoy your videos and its been 25 years since I saw a "Tiny Tiger" 500 watt noise maker. I have a funny story about it. Dad bought one in around 1965 when K Mart had them on sale for $89.99. The next year we took it to Indian Creek resort on Priest Lake in Northern Idaho. It had both primitive tent and trailer sites and our old 1941 Cozy Coach allowed us to to be in a newer section that was being wired for 120 hookups. When we got settled and set up, a park assistant came around and apologized that the power wouldn't be on to our site until Monday. Dad said "no problem, I have generator". The Tiger and him got along well, it being mind numblingly noisy and him being a total Asshole. Within an hour of him firing that thing up, the juice was flowing in the campground and Tiny was never used again to my knowledge until he died and I got it. It still fired right up and I sold it to a guy for $25.00 at my yard sale.
That was a great video! Awesome little tools.
Wow do you come across some odd ball machines! Keep up the good work!
Worthy of Tim Taylor's Tool Time!
What you need is a Laser cutting machine. they generally look and run like a standard printer, but will allow you to cut out anything in the shape you want. these machine are used for all sorts of things including etching and engraving. They can be found new for under $200.
This would be perfect for making brand new gaskets to the same dimensions of the old gaskets you are removing.
FFR: Aluminum pop can cut into a broad strip the wrapped around a pin and clamped tight makes an excellent gasket hole-cut at the tip.
I have watch model steam engine guys rebuild the steam valve box and when they put the gasket material on, they just drill the holes for the bolts and then trim the excess off afterward. Just a suggestion. I love the videos 🤘🏻
For a bit there I thought you’d be 0 for 2 but ya pulled it off ! Around here our ice augers run motors much like those . And the carbs are real touchy !
