Tecumseh Vector vlv55-501004 Kick Back

This tecumseh is kicking back when you try and start it. I removed flywheel and have checked the flywheel key (611154) and it looks ok. I tried a new blade with no luck. Crankshaft does not appear to be bent. I removed the head and valves appear to be working ok. I have a new flywheel key on order just in case. These vector engines are a real pain to remove the blower housings etc. I guess it is possible it could have jumped a tooth however I have never had one do that. I can check where the flywheel magnet is at TDC however like I said it is such a PIA to remove the tins. Any suggestions would be appreciated.

Check the blade adapter and see if the key made in it is sheared.

Cheese - removed the blade and blade adapter. The adapter was fine. Do you have any additional suggestions to try. The new flywheel key is due in on Thursday.

That's about all I've got. Let us know where the key key gets you.

Cheese - sorry this took a little while, I had a John Deere tractor I had to finish first. I installed the new key and also cleaned the top of piston, both valves and the head with a wire brush. I finished putting it back together this morning. The engine started on the second or third pull. The old key had a slight groove on each of the sides. I thought that was the way it was made. I guess it was really partially sheared. I have it running outside now and will let it run for about 20 minutes than I will try and start it again. Looks like this one is closed. As always, thanks for your help.

Yep, even a slightly sheared key (I call it "pushed" when the key looks like that) will do it. Glad you got it!
