RTV silicone

$450 plus $30 shipping if you are in the lower 48 USA states. I only sell on ebay.

i made the pump from parts from a 50cc honda engine. ebay has them cheap.

the pumps are made by me. the triple has a centrifugal pump from a Jerry Howell design. the twin has an internal gear pump made from a 50cc honda engine oil pump available on ebay..

@@abcdefghi6046 awesome thanks!

yes they are from an OS engine. yes, its on glow fuel.

I do and I've tried but physics and geometry dont let it happen.

I machined the outside of the cylinder and then made a thin-walled hollow tube with a top and bottom. the tube i.d. is a shrink fit onto the machined cylinder. loctite seals it. two holes for water fittings were added before it was installed. everything is for sale. are you interested?

Search googl for a 1934 for wiring diagram. A 12v batter is fine for the starter but you will need a resistor to drop the voltage to 6V. The starter solenoid can be an inexpensive three- terminal one. Wiring a start button and on- off switch is just a. Simple set up.

I would pull the intake manifold off and check the flatness and gasket seal. The gasket should not be installed with any sealant otherwise you're sure to have a leak. It could also be a cracked manifold or a leak at the vacuum line fitting connection for distributor advance. John

Check the back of carb between the cast iron base and the main body between the two screws that hold those parts together. they get over tightened and can warp the main body and allow a major vacuums leak.

Hi, it's me again. I was very curious how you made the water jacket? I have 3 of the O.S. marine 4 strokes, but they are so rare that I don't want to use them. I'd much rather convert a standard 4 stroke to water cooling. I see your water jacket design is very similar to production marine engines. It appears you machined the crankcase and head fins to be round on the lathe, but thats as much as I can tell. I'd really appreciate it if you could elaborate on the design of the water jacket. I also enjoy machining and tinkering with model engines. Thanks! (Excellent channel by the way)

@@timjs1018 Thanks. Yes the water jacket is a hollow chamber that i shrunk-fit to the machined casting. loctite 609 sealed it. the fittings are held in with JBWeld. the ignition set up is via Jerry Howell ent. Everything is for sale...

@@abcdefghi6046 Is there no inner wall to the chamber? The crankcase itself is in contact with the water? -Tim

@@timjs1018 Yes. I machined the head also so that it matched the diameter of the jacket.

@@timjs1018 Yes you're correct. also i machined to head so it matched the diameter of the water jacket.

Please try again to comment on the OS FS 120 video. I believe comments are now enabled.

check out 2stroke stuffing he fitted a 4cyl 3,5cc engine to a moped -broke the crankshaft - then switched it for a 2stroke 3.5cc which worked (for a short time)

@@malakiblunt yeah I saw that, it broke because the crankshaft isn't supported in the middle

sure. it took many may hours to build. $2000.00 US plus shipping. i would list it on ebay.

Also if u would sell it how much I’m interested in it.

no

It was an idea or suggestion, I’m not asking.

Yes

@@abcdefghi6046 Very nice craftsmanship. Good job.

thank you. i bought it on amazon. there are many types. the filler neck and cap were made by me. the cap is aluminum and the neck is brass. its held in-place by JB Weld epoxy.

@@abcdefghi6046 Thank you for your quick answer.

I think it's just a pc water cooling radiator.

Not really. It largely consumer engine parts. cylinder heads are just 4 stroke RC engine components Still cool though.

thank you.

@@zuestoots5176 bruh I bet u could never do that this thing is dope as fuck

@@zuestoots5176 where's the video of your custom one off everything made at home engine if this is so unimpressive and off the shelf parts 🤔

I'm agree, better if installing exhaust muffler on in.

it sounds cool

Sounds fine, its a 3 cylinder, Odd cylinder count engines always sound a little off

Sounds like you're jealous to me because you wouldn't have a clue how to make one yourself! The engine is a work of art, just accept it.

Sounds awesome wut r u talkin’ about
