make sure its a similar i/d. a honda gx120 or a small pitbike carb might work.
as for the sparkplug, could you tap it a larger diameter, then drill and tap some threaded bar for the spark plug to go into?

Im starting to agree with blue and i think im gonna postpone this project until i can get money to do a full restoration and get new parts and make it nice, etc. id rather wait and make something nice that works good then get something to kinda work taking all the shortcuts.

First thing i woud do would be pull the carby off and drop it into a tub full of deisel or kerosene or similar than out with the spark plug and check compression i would squirt a little wd40 in the barrel to help lube it up a bit than test compresson dont put oil down there as it will mess wth the compression reading, once you get a reading you can make your mind up wether it needs a full rebuild or if it is worth the hassle, Than i would test the spark if there is no spark go through the process of elimination untill you have spark, once you have that sorted go back to the carby and after a few days in the wash hopefully will be free and all parts movable, than inspect carby remove bowl and slide and clean it unclog holes and make sure the float works...... But yeah if its screwed well i guess its screwed i am sure you will find a carby of a simular engine or a newer kohler?

Sorry i am a bit late on this after reading the thread propery i must say just get rid of it, I meen if you are not realy into the vintage part why bother, I meen if you want the original engine buy one working later it will probably cost you less any way....

you do the test when the engine is intact and a compression tester is a gauge you push or screw into the spark plug hole than turn the motor over, it just messures how mutch pessure build up inside the engine... The more the better, if compression is bad it means the rings are worn allowing air to slip past tham, you can get a cheep tester for about thirty bucks but if you ask every one you know someone is bound to have one they could loan to you.

Just saw this araldite putty stuff today and it said fixes stripped threads. I dunno if it would hold the heat and compression, but wortha try?

i figured id just buy another head instead of taking the cheap way out. (im gonna have to get one in the long run) right now im trying to get some cash so that i can keep working on the motor. i know this is kindof offf topic but it just came to my mind. would this engine be able to power an offroad go kart with some decent torque and speed? and how do you hook up old car wheels to a live axle? like the old donut style tires?

does anyone know what size shaft this is??

on youtube i saw a vid of someone who put a chainsaw carb on a 5 horse briggs and it ran strong and revved higher. i have an old weed eater thats all taken apart. what are the odds that it'll work??

that sould have the opposite affect

the engine would run too lean if at all

EDIT
wait unless it was a chain saw of similar cc then it might work

Thats weird, i wouldnt think it would work.

Anyways, i tell you that its not worth fixing unless you make it nice, because i was restoring a tecumseh built from the 1950-1970 time period, i washed all the parts, worked hard, then slapped on some high temp rattle can paint and called it GOOD. it lokked amazing. After a week, the paint was totally dry, and it looked bad. I rushed the final stuff. Now i dont like it.

Im thinking seriously about getting this to sandblast the paint off and make it factory again.

I got the engine last fall and still havent heard it run yet! It will be a while too. But take your time, get it spotless, and it will be rewarding, like you got a brand new kohler 4hp as it came off the production line many many years ago.

Good luck.
