    5hp Briggs with up draft carb, looking for carb or gaskets

    Hi folks. I picked up an old Sears Craftsman Generator with a 5hp Briggs carrying the numbers: 150 12 0105 01 90041007 So I know it is a 5hp, and looks like it was made in 1990. It will run, started up with a splash of gas. Updraft Carb is very dirty. Tried to save the bowl gasket, ripped. So...

    Tecumseh H70 aftermarket piston ring direction

    I have an H70 I got free, came with a new aftermarket piston, rod and rings. There are no instructions on the installation of the rings (rings were in a sealed package, not tapered with). The oil ring had no bevels, nor did it have the wavy inner ring I am accustomed to. So I put that on as is...

    HS50 bottom dead center issue?

    I did another post on this engine but hopefully can be more specific here. When my HS50 hits bottom dead center there is considerable movemnt of the crank before the piston moves again, the result is hard to pull start and breaking keys. The bottom dead center issue is shown here, cue'd up on...

    I picked up a Snapper snowblower freebie with an HS40 55552L on it. Found the cam broken in 2, trashed one tappet, chipped out a piece the inside cup where the cam sticks in (JB Weld it back on?) I am looking for a replacement camshaft. Now I'm not sure if this engine will be used for this...

    1970 Honda CT70 removing rattle can paint job to reveal original paint!

    Hi folks, I was working on my CT70 that has a rattle can paint job (painted over 20 years ago by PO) that is ugly and was thinking about doing a paint job. I had tried to get the paint off many years ago with less than spectacular results on the forks. So I decided to try again with a variety of...

    What is it?

    I picked this up today on CL. No name that I can see. Handlebars I think are bicycle, rear wheel looks Harbor Freight. Color is light purple-ish rust. Frame look straight, engine plate is loose. 2 cool home made fenders and 1 that looks original. Seat with frame, at the very least has been...

    Looking for a high profile (tall) rear tire for a 5 inch rim.

    I have a Manco Rim with a 60 tooth sprocket that is a bit tall for the tire, it will dig into the ground on a slight turn. The tire I have now is about 11 inches high, would be nice to get 13-14 inch height. Any ideas?

    5" Manco Wheel Rear 72 tooth Sprocket #35

    I bought a 72 tooth sprocket. 6 hole for my 5 inch Manco rear wheel. The problem is the sprocket is nearly as big as the tire! (lol, didn't consider that) So I think I need to at least drop to a 60 tooth, maybe 54. It will effect the gear ratio I realize, but I don't know what else I can do, a...
