Love those vanguard motors. Have the 16hp in my 1990 simplicity zero turn. It is very much worth your time and money if you choose to rebuild. People will pay a lot of money for one of those in good working condition. Just give her a bath, change the oil and filter, make sure the carb is in good shape, and seafoam the hell out of it and sell it. Hell if you are in NC I would consider purchasing myself for a go-kart.
I'd pay well over $40 for it. Three things I would do before mounting it on a machine, after cleaning it up, are pull off the crankcase cover, and replace that gasket, and while you're in that area, replace the dipstick tube seal and the PTO seal. Those gaskets are notorious for being flimsy and failing because the bolts eventually work their way loose. There is a gasket kit that comes with a beefier gasket and new bolts, with a little thread lock on them. The dipstick tube seal will also wear out and leak. Great engine, in my opinion, just a couple of design flaws that have been made correctable.
My guess would be it's carbon burning off the inside of the head, watch that cylinder and you can see orange flames. The piece you took out of the one exhaust port is a restricter to get the correct back pressure. They use that so they don't have to have equal length exhaust pipes and the muffler can be closer to the block.
I had one years ago I took apart was nothing wrong with it other than carbon build-up and it was the carbon that was igniting and coming out of the exhaust
Clogged air filter caused rich running and carbon buildup. The thing you pulled out was a bushing for a muffler pipe. Change the oil, put some pipes or a muffler on it and run it and set the idle mix. After it gets limbered up check the valves. Dandy engine right there. GBWYou!
We have had quite a few times in our shop where we'll get one in like this and we clean the heads and block cause of excessive carbon build up, The way the sparks fly and how weak they are says a lot about it just carbon just burning off. You scored big on that I only dream of that deal. lol
i seen that screwdriver sitting there while you were reving it up, luckily the motor didnt slide and the flywheel caught the screwdriver. i didn’t actually see anyone else mention that, coulda been baddd real quick lol. but cool video though.
I think that the sparks are just carbon burning of because it was sitting I had a mower that was strait piped and the engine sat for a year and it would do that for a little bit then it stopped.
Like Starpuss says looks like carbon burning off. Plug was really Carbon all up like it had been primarily idling long periods. Try putting exhaust on it and maybe a load and see if it clears up.
Without it hooked back up inside it can cause constant flooding.& Sparkplug fouling continusly due to that reason alone. It wouldn't be inside of the carburetor if it didn't need it at all. It's for controlling the automatic choke machanisum inside. Witch works off vacuum controlled pressure feed through the fuel pump unit.
That rod you cut needs to be revoked back up to inside.after reattaching the mufflers back on to that engine to. It runs off vacuum controller feed to pulsate fuel from the pump into the float blow from the fuel tank.& Fuel line filter to to help with keeping out dirt.&'debris from entering the carburetor to witch is the main purpose of inline fuel filters to begin with.
Your vids never disappoint. You are by far my favorite channel on TH-cam. RCG, I just wanna thank you for all the work you do to bring us these vids. Also thank you for teaching me how to work on small engines. I've learned so much from you since I've subbed your channel years ago. Keep up the awesome work my friend!!
Yeah, I'm pretty sure it's just burning off some carbon deposits. Back in the old days on a car engine we would dribble about a quart of water down the carb while holding the throttle at about 3000 rpm. That would cause all the carbon to blast right off the cylinder heads.
Or what is called quiter sounding.& Smoother running engine then without the exhaust on that engine at all. Cause it's actually loosing compression to without the mufflers attached. on the engine to begin with anyways truthfully there computer geek!
"Diaphragm Fuel Pumps" are relatively inexpensive, but this engine definitely needs a Valve Adjustment since we have no Maintenance History on this. Oil Flush would be a good idea! To "FLUSH" ADD 2-3oz of Berrymans or SEAFOAM into the Crankcase and run for about 3 minutes and drain the oil. This will help dissolve most of the "SLUDGE" and help clean the Internals... But being RCG, you already know this! Thanks for sharing this Vanguard, -T🖖
I've been wondering if the vertical shaft version can easily (or even) be converted to horizontal? Any ideas? I've so not reviewed the parts and haven't found a horizontal shaft 18HP version to compare. No videos online either. Are for L-heads conversions to horizontal from vertical... though not for OHV Briggs that I've seen. Both mine came from White GT185's. Great detail as well and nice to see a Vanguard V-Twin 18HP video... both mine were reported as working so I haven't bothered working on yet and am about to take the one I transplanted into the JD240 (homebrew Ford320 in progress) out and replace with a single cylinder OHV Briggs (wanting to have all mine single cyl OHV or opposed twin Briggs). Valve lash... though I've not worked on the V-Twin's much? Totally neat seeing you working on and I'm also curious if the valves maybe neat cleaning or really just what does it look like under the cover and inside deeper? Thanks for sharing er!
To my knowledge only the 18hp kohler oppy twin was ever made factory convertible. Even then it was know in the vertical shaft configuration to have oiling problems. There have been many arguments over the years on if a pressure lube briggs could be converted by tapping into the pressure side and feeding it to the valves. But to my knowledge is has never been pulled off.
dood. been watching you a long time. im not a safety karen by any means, but having sparks flying from the clamp on the pack, and the exhaust while holding an open container of gas ... not a good move. try not to catch yourself on fire man.
B**** Burnley Court carbon out of the cylinder it's a good motor he could be rebuilt I've got a vanguard that's got the red cover and it costed me a hundred and some dollars for a kit
What is the "HP Rating" on the KOHLER V-Twin you just revived? I don't think you stated that within the Video. Any plans on Fabricating/Starting John's Bulldozer/Tank Build? You don't need TRACKS Yet! I'd say Kohler or Briggs Horizontal Shaft V-Twin Engine and use the Hydraulic Drive from the Zero-Turn for the drive...
Not only holding on to thing of gas by the exhaust then you putting the open gas next to the starter with all the sparks are you trying to start your hand on fire then then your reaction dropped the container of gas it gos all over then you have gas all over in your shop on fire way your trying to put the fire out on you hand your O 💩 so may I ask not do that in your shop it be much better lot longer gas line an put a gas can way from your work please. I use a small boat gas tank when I start up engines and a bottle of gas that don't leak an with smaller hole. Both said are sparking but that one next to you is sparking more
before i fire up an engine that has been setting , i lube rings and everything i cant with tranny or 2 stroke.carbon is one of the hardest things on earth. id rather lube it up before i shot carbon though the motor. and pull the heads and clean piston tops as well. you know this better than me. in the future how about turning a vertical oppy briggs to run horizontal . watching you do it first would sure help..
Nothing wrong with her , just carbon burning off.
First time they run without an exhaust I have seen that before a few times , but i would definitely adjust the values.
RIGHT!
man u have balls to spark the starter like that with gas exposed like that
Real scary stuff. LoL
Gonna stick with the majority, it's just carbon burning off. A good cleaning, or a dose of berrymans or seafoam would do wonders.

The small tube in the exhaust are exhaust port liners. They there to help with exhaust heat so the engine doesn't over heat.
I'd pay well over $40 for it.

Exhaust port sleeve was used on older models to protect the port. Newer models have better alloys so collar is no longer needed.
My guess would be it's carbon burning off the inside of the head, watch that cylinder and you can see orange flames. The piece you took out of the one exhaust port is a restricter to get the correct back pressure. They use that so they don't have to have equal length exhaust pipes and the muffler can be closer to the block.
That fully explains the exhaust piece and why i had never seen one before. Thank you Ed!
Don't think that is correct. Newer vanguards don't use them. BS Vanguard tech told me it had to do with high heat. New alloys are better.
The OHV AKA valves need adjusted on that engine. Go ahead and check out the piston rings in it to.
I had one years ago I took apart was nothing wrong with it other than carbon build-up and it was the carbon that was igniting and coming out of the exhaust
I am rebuilding a vanguard v twin 16hp vertical shaft. It blew a connecting rod and broke the piston on the left side.
Clogged air filter caused rich running and carbon buildup. The thing you pulled out was a bushing for a muffler pipe. Change the oil, put some pipes or a muffler on it and run it and set the idle mix. After it gets limbered up check the valves. Dandy engine right there. GBWYou!

And oil needs changed to inside of it to. Along with muffins AKA muffler's put back on it to for compression.&quiteness to.

40 is theft for that engine xD
Exhaust ALMOST fully closing.
In other words, it needs cleaning and lapping
That thing in the exhaust is a Hepa, epa exhaust restrictor to comply with That fuel eff. bs they do nowadays.
Yep carbon, but it came from somewhere..rings or valve seals? I'd adjust the valves and run it again, see what that does.
I put My money on just carbon being blown out by combustion.
And intake valve tubes connected together as one system.
4th of July is coming up in a couple of months, set it out in the yard after dark, crank it up, run it and enjoy the sparkler show.
Petrol just like diesel engines carbon up over time from too much loading. That's why you never bog down aircooled engines.
standing that close to an engine with zero muffler, not even pipes on it. it's making my ears hurt just watching it. PPE goes a long way my friend.
I'm thinking that it might carbon deposits being spit out of the exhaust
Shake hands with danger
Possible burnt valve or adjustment
carboned up. it needs carb cleaned better too

I say put that vanguard on a good wheel horse mud mower
I have an older 20 horsepower v-twin intek on my older Craftsman ride-on mower well I grind it off the starter gear on the flywheel😢
Valve Job, clean the carbon off the valves.
Or what is called quiter sounding.& Smoother running engine then without the exhaust on that engine at all. Cause it's actually loosing compression to without the mufflers attached. on the engine to begin with anyways truthfully there computer geek!
At 10:00 i should call her... 😆
Looks like carbon burning off the exhaust valve head etc. Doesn’t seem like much too worry about seeing worse.
Is part of the old muffler
If you rebuild it rebuild it for a race mower in the name of the the race ca
Gaurd
Meant to say race guard
my cousin has a carpet cleaning machine with a 21hp vanguard and it sparks too.. not that bad but it does
cool.
You need to get an old gas tank and line to feed in the gas. Your going to catch a good fire if not careful. A real good fire. Stay safe
Great video today, keep em coming
I say its valves and seats or it running lean on gas. I say its the valves an seats.
Do a compression test.
"Diaphragm Fuel Pumps" are relatively inexpensive, but this engine definitely needs a Valve Adjustment since we have no Maintenance History on this.
Oil Flush would be a good idea!
To "FLUSH" ADD 2-3oz of Berrymans or SEAFOAM into the Crankcase and run for about 3 minutes and drain the oil.

I have a 18hp vanguard vertical shaft that needs a crank seal cause it leaks oil from there. How hard are they to replace?
I have never done one on these but on all the others I have done it is not hard. Just be sure it is in fully square or it will blow again very quick.
Could be something in the valve train that's not happy
I have seen that before you are blowing out the carbon
dood. been watching you a long time. im not a safety karen by any means, but having sparks flying from the clamp on the pack, and the exhaust while holding an open container of gas ... not a good move. try not to catch yourself on fire man.
👍
B**** Burnley Court carbon out of the cylinder it's a good motor he could be rebuilt I've got a vanguard that's got the red cover and it costed me a hundred and some dollars for a kit
im pritty sure i have one of those carbs
Nothing wrong with that engine.
See about Rering It
thats probably why the motor was scarped, the fuel pump and carb....als/either what it was powering broke.
What is the "HP Rating" on the KOHLER V-Twin you just revived?

Nice
just clean an run its just carbun ,its comming out of both side dude it has a lot of life left
i think it is all carbined up from to much fuel.
I’d make a viddia of shooting it full of holes then sell it for art, call it “the vented vanguard”
Looks like it burning the carbon build up in the cylinder to me
maybe it has a lot of carbon build up that is burning off...........
It's carbon
Not only holding on to thing of gas by the exhaust then you putting the open gas next to the starter with all the sparks are you trying to start your hand on fire then then your reaction dropped the container of gas it gos all over then you have gas all over in your shop on fire way your trying to put the fire out on you hand your O 💩 so may I ask not do that in your shop it be much better lot longer gas line an put a gas can way from your work please.

🤦🏻♂️🤔🧐
first
before i fire up an engine that has been setting , i lube rings and everything i cant with tranny or 2 stroke.carbon is one of the hardest things on earth. id rather lube it up before i shot carbon though the motor. and pull the heads and clean piston tops as well. you know this better than me. in the future how about turning a vertical oppy briggs to run horizontal . watching you do it first would sure help..
Its funny you brought of the conversion. 6 others have as well on this video I will think on it as I had 4 spares right now.
@@redneckcomputergeek thankyou , your channel is always interesting . i enjoy it very much.
