upstateyankee50 59 #1 Posted April 15, 2022 (edited) well guys ;now that I have the B-80 issue out of the way ; here is another hair puller as most know last year I did send a post as far as my 10 horse Tecumseh that has issues starting ;winter came and everything that came with it gave me no choice but to let it sit ;so now it is time hopefully I can get the problem of it not wanting to start 'first of all most told me it was a carburetor problem so I went out and bought a brand new one at the cost of 95.00 ouch that hurt ; but that was not the issue 'as most know this 10 horse has the solid state ignition on it and during the test that I have done it has spark from the unit to the plug I have set the gap as according to the specs and still it will not start ;I did chat with the owner of A-Z and he told that it could be the key way which has worn or even moved ;no I have not removed the fly wheel which will be done though I did remove the nut but I really can't see in it as the hole is so small so I can not tell if the key is the issue ;using a small screw drive it went in about 3/8 so really I am not sure how long or how thick the key was is or what size it is again any thoughts would be appreciated ;it is just odd that for the years that I have owned this it always started ;and yes I have checked the wiring which is alright Edited April 15, 2022 by upstateyankee50 1 Share this post Link to post Share on other sites

Have you tried spraying gas or brake clean in the engine to see if it will fire over for a few seconds? 1 Share this post Link to post Share on other sites

Have you tried spraying gas or brake clean in the engine to see if it will fire over for a few seconds? yes I have done everything and with the gas being sprayed in the carb it will only run on it I even took the hard off and found 2 head gaskets which there should be only one but by removing one there is a leak in the head and yes even removing the plug and spraying gas in the plug hole still didn't work 1 Share this post Link to post Share on other sites

If you get a sprayer or squirt bottle of gasoline will this test continue to work over and over? 7 hours ago, upstateyankee50 said: found 2 head gaskets which there should be only one but by removing one there is a leak in the head Have you had the head planed?

Change the plug and see what happens. odd that I have tried 3 different new plugs for this model and they did not help 'why is that it always the plug that is the issue 'again fuel is getting to the carb from the fuel line to the pump and out to the carb plus the fuel bowl has fuel in it when I drain it ;it might be the carb which I did have it rebuilt but did the shop do it right plus a brand new carb for this model it still won't start ;a few has told me that it could be the key way on the fly wheel so that is my next thing to do Share this post Link to post Share on other sites
