A junk mower makes a good test stand. Don't need anything but the frame and fuel tank. Maybe some cables, battery etc. if you want to get fancy.

Old picnic table would work too, or any large wooden table.

Well I just picked up an old craftsman with this exact same motor. It is doing the exact same thing!!! Feed it some ether and she backfires. That is the end of that. Has GREAT compression. I have done a small bit of research and found that this is a common problem. Different people swear to different things, and I have heard that it could have loose valve seats, or could have carbon buildup on the intake valve or on the intake valve seat. I just can't decide whether to pull the head or not...

Have you checked the valve adjustment? If not I would start there.

Does that include the timing key?

Do you think it could be that? It is a mower from an auction that I got for 25$ so that i am not destroyed if I can't get the heffer to run, I just have never had a Tecumseh before and would like to run one and learn about them more. Knowledge is power ya know! I personally think that there is just carbon buildup on my intake valve so it can't shut all the way, but the weather has not been cooperating and I have no shop space for it so I have not pulled the head yet. I will check the flywheel key though. Are these motors good even though?

Well hot dang Doc ya did it again!! Pulled my flywheel and yep the flywheel key was. Sheared right in half and the flywheel had rotated about a half an inch on he crankshaft! That would explain the backfiring!!! Now will the flywheel key out of a briggs motor work? I really hate puttin an aluminum key back in it... But a huge thank you ya saved me many hours worth of work there Doc. I might even name this build Mule! Lol

Would two Briggs and Stratton carbs fit on my Tecumseh 18hp OHV v-twin dual carb??

I have a question about my 10hp Tec flathead; how can I get more power with simple mods like swapping carburetors? it has a 12hp OHV carb on it now and i cant seem to get it tuned right
