hi all,
i have a old Tecumseh 4 stroke that keeps shearing blade boss bolts and keys. I have had to replace the bolt that screws into the blade boss twice (not the one into the crankshaft).
i have also had to replace the key on the crankshaft once.
it has very good compression, and starts 1st pull with no real kickback. I donοΏ½t know what to do next. Could it be an incorrect coil gap causing it?
Thanks for you ideas,
regards jay
