3.5

Hello all, We have recently acquired a manco thunderbird that had been sitting for several years. I started it and it ran for three minutes before it wouldnt start again. It had about 40psi of compression. We took the head off, cleaned the valves piston and head, tried to start it again and...

A little side project I've been working on while waiting for the powder coater to get done with the Ruttman. Nothing fancy inside, just a stock late model 90000 series flathead. Swapped crank to make it minibike suitable. More pictures to follow as I finish detailing.

This motor is new never ran I haven't even knocked the dust off it the crank is keyed and tapped the box that is in is original but not pretty and has a shipping date on it from 1967 so I'm figuring that if dates prity close to that. $400 and you pay shipping.

I want to repaint a 1970- 3.5 Tech motor. What white paint do you use(mfg). Want to rattle can it. Thanks.

Hello! Even though this is a vertical shaft Briggs and will never be on a minibike, I thought this was the best place to ask because of all the helpful people on this forum :thumbsup: :scooter: Does anyone know the part number of the diaphragm and gasket for a vertical shaft Briggs 3.5hp...

Had this engine for years sitting in a box half disassembled....like just about everything is around here :doah: It was complete but tired condition ebay purchase some years ago. I didnt need it, It was just a smart buy I felt at the time. I dont have any pics of how it looked, but...

Question Will a 5HP flathead briggs tank mount on a 3.5 HP briggs flathead Or are they different. Thanks

Redoing a fuel line and was wondering what the affect of the gas being heated running so close to the engine.

Hi, I have not been around for a 1/2 year. But I finally put some paint on and re-upholstered the seat, new tires and a few do dads. I took some pictures to show it off. It is a Bird Duck, with 6 inch tires, scrub brake, 3.5 HP Tech. I just have to hook up kill button, route throttle, gas...

I have no clue if this is even possible but I would like to either have my existing 1970s Tecumseh 3.5 totally rebuilt to be as new or buy a complete New Old Stock (NOS) one. The model # is H3545196H My existing engine runs and is complete but is wore out and needs complete rebuild. If...

Looking for a small Tec for a rat project. Does not need to be pretty but must be a clean runner. Prefer white but doesn't matter. Old is better but newer is ok. Forward tank. Cash waiting... What ya got?

Is it possible to use a brand new coil off a 3.5 tech motor vertigle shaft, on my 5.0 tech horizontal shaft motor? I'm not even sure if they even look the same. The very shaft rotor tiller was given to me because the tiller part was frozen stuck! The man said he just replaced the coil and carb...

Got this nice little Craftsman 3.5 Tec for free. Runs pretty good, except for the diaphragm carb leaking. The primer connection on the bottom of the diaphragm is leaking pretty good, and it leaks gas into the air filter when sitting. Since I am putting it in a minibike, I would like to...
