Re: Tecumseh won't start
When I usually get a engine (used). I run through it pretty quick. I wire tie the stop/safety lever, pull the recoil rope, and listen for compression. If I think it's there I tear the carb down real quick checking float movement, passage clearances, orifices on bowl bolt, hole going up from there to carb (metering port) looks good I reassemble carb and check coil gap for proper clearance (no gap no spark), then I proceed to spark plug (proper gap, clean and check for cracks0. Finally put clean gas in with hose to carb off and check for free flowing gas. Reassemble everything and give it a shot to see if it will start. I am used to doing all this. Takes about an hour doing a thorough job. It's worth it if you really are going to use the engine. If I have to, I'll give it a compression check. After doing them for awhile you will be able to tell even before pulling that rope or turning that key whether or not that engine is good. Good luck, hope this helps a bit.
