Love that you are doing the clone wars! I have built two parts kits clones a 440 and 372. The 440 was my first one and really taught me a lot and got me into building. For the price and the fun you get, I think they are great! They are so fun to mess with and try out porting and mods without breaking the bank or feeling guilty for screwing something up.
No kidding. These would be pretty fun to play with. Blowing up a $1000+ saw isn't something I can even consider, but a $250 saw I won't be broken hearted about.
Loving these videos, testing different items to see what actually produces power. My 13 and 14-year-old boys have just gotten into porting, and this is super helpful. Thanks!
Joe run an 8 pin that saw will easily run it. You have machining tools so you have a huge advantage there. I built one with only porting and base gasket delete and it still had a terrible squish clearance I believe it was around 40 tho. I timed several runs between a 7 and 8 pin and the 8 won by a pretty substantial amount.
Can you show how you check ignition timing on a saw? I’ve always just used a timing wheel to see how much cutting the key advanced it and then just going by feel of how it did….but I’d like to see like actual timing numbers with a light? Like to see where it’s firing? The reason I ask is I have heard these clone 372s are having some poor ignition timing where as in the past these 372s are kinda known for not needing ignition timing advanced. Vs for example a 272 you almost always can get some gains by cutting the key .030 or .020
Badass dude! I have a g372 thats a turd, even with oem walbro carb... wondering if my porting is the issue... thanks for including the timing numbers.. 🤙
What piston did you swap in to that saw if you don’t mind me asking sir. I love your videos. I wish you could make one every day. I’ll take what I can get though. Lol
Ooh ooh, JOE TELL ME MORE ABOUT THE TIMING ADVANCE! how many degrees? Did you cut the key way wider in the correct direction and shove 2 keys in there? Or weld it in and cut a new keyway? My ooold 372xp, hozzlforma, I ported very mildly, piped it with uncle harve pipe out of anodized aluminum pipe, and big bored, pop up, still seems like it's got a lot more to offer
First video of yours I've watched. You Tube algorithm recommend it. Around 30 years ago, two stroke tuning was much better known by various racers, motorcycle, snowmobile and boat with larger motors making 50~200bhp from 125~750cc motors (and more when cooling available on boat motors running around 80 deg C) Seems the chainsaw guys are the only people doing it nowadays? What is the capacity of the motor? Does it relate to model number ? (eg, 372 is 72cc?)
@@dynojoemods2764 i‘m going to lower mine to around 180. Now its a bit much i believe. Whats the Partnumber of that 044 Pistonbolt? I think that could compensate my welded Popup which has 85 Gramms . Thanks Mate
@dynojoemods2764 I'll try it and see how it does. One more question I have a g660 and I'm thinking about trying a big bore kit. Are there any tricks to them?. I've seen a lot about them running like crap and some good.
The counter weight on the crankshaft has to counteract the forces of the up and down weight. In a single cylinder you cannot achieve a perfect balance, but you can balance for a certain rpm range. Where the forces cancel out most of the harmful vibrations. But it is only effective in a short rpm window.
@dynojoemods2764 thank you. I was aware of how a rotating assembly in a V8 for example would need to be balanced, but I couldn't understand how a single cylinder would be affected.

Hi Joe, very impressive! Thanks for sharing. Good luck
Awesome video can't wait to see more

Good work Joe. I love watching and learning what little tweaks do to change the power. Very interesting. She sounds much better than that first pull.
Thank you for your videos.
Awesome work as aways joe
Love the videos. Love from New Zealand
Nice work!
Awesome video.
Very cool Joe, I'll try a advance on one of mine now!
Awesome video buddy!
Love your channel man, keep it up!
Appreciate it!
Good job Red.
Thank you!
Awesome work..
Thanks a lot 😊
That's very impressive, I hope it holds up til race day and beyond.. can't wait to see what you can do with my 572xp! 👍
Wow! Great work Joe! I have a g372 on the way and will def be checking and advancing the timing now! I love your vids man.... Keep it up!
You could get some spark plugs indexing washers to shim out the plug a little if necessary.
Great video friend
Nice work Joe, interesting to see the gains from timing advance. Almost 9hp😮

2hp from a timing advance is crazy!
👍👍
I need to send you a saw or two. Gonna have to figure out how to advance my 372 clone

How's that piston compare to a 268xp piston.
If you need to borrow a standard handle let me know.
What piston did you swap in to that saw if you don’t mind me asking sir.

I would like to get my saw dynoed. But you are far away from me and I dont want to be without my saw. Awesome work. Cheers
Maybe one day!

Nice work Joe. Been looking for one of those bendy torch things for poking in cylinder when porting. What breed is your one?
Streamlight stylus reach is this one. Only thing I dont like is it uses "AAAA" Size batteries. But it fits 10mm plug holes.
Please file the outside side of the cutters, so that the drag of chain is reduced. Ie, the cutters are narrower closer to the bar.
Usually they "stone" them to serve that purpose.
you don't have to buy full wrap handles - they have the normal ones as well...

Bagaimana perporma mesin itu bos. Apakah persis tenaganya dengan yang asli huq
How much one of those go for ported joe?
I think i can guess what that piston is. Pretty sure it comes from the other orange saws
What was that new piston?
I'm kind of curious what kind of numbers would it get with Advance timing done to stock If it was that bad With none
I'm sure it would give a noticeable bump.
Nice Job , how high is your Compression with that Piston?
My Built has 210psi at the Moment.
Not sure. It feels decent, I'd guess 180 ish. But haven't put a gauge on it.

👍🏻👏👍🏻👏
You have any of those big cc yellow saws for sale im really wanting a yellow or jonsered 2088 or 83 or its yellow brother
Sorry, only the smaller ones.
What would be a hot fuel I could use on a firewood saw? 100cc
Can try more octane and a timing advance. But fuel alone won't change power output dramatically.
I wonder what the ignition timing was at after the advice 🤔.
Not 100% sure. I had moved it around quite a few times just watching to see if power gained or dropped.
@dynojoemods2764 I have orange gray g372 and it was 30° with a timing light. Makes me wonder if it would like more 🤔.
@@chrismuncey3861 30-35 seems to be pretty common, but you can try a bit more advance and see if it likes it. It will pop and stuff if you go too far.
@dynojoemods2764 I'll try it and see how it does. One more question I have a g660 and I'm thinking about trying a big bore kit. Are there any tricks to them?. I've seen a lot about them running like crap and some good.
How about some finger ports? Whats your thoughts
Not a lot of room for good flowing fingers. But might have to try it.
❤️🔥🇺🇸
Its not a flop...u needs de Noker powa's 😅
Nothing can save the knocker
Is 390 carburetor allowed?
The clones are supposed to use the kit/oem replacement carb
Why did the torque go down?
Part of that could have been the saw was way more heat soaked than normal. But it isn't super high compression with the higher exhaust roof either.
How do you find coil timing?
Using an automotive timing light.
Ok thank
Joe, have you tried a 268 windowed piston?
Not yet. But might have one in the works.
I built a clone saw with one. Did some mild port work and it runs good. I'm sure you can build a much better saw.
I'm confused as to how an assembly that goes up and down affects the balance of an assembly that goes round and round. (On a single cylinder unit)
The counter weight on the crankshaft has to counteract the forces of the up and down weight. In a single cylinder you cannot achieve a perfect balance, but you can balance for a certain rpm range. Where the forces cancel out most of the harmful vibrations. But it is only effective in a short rpm window.
