Got a question. I have a 6.75 HP Tecumseh engine that I am having some issues with. When I got the engine it didn't run. I was told it was from a bad flywheel key, which I confirmed it had. I replaced the bad flywheel key and tried to start it but when I pulled the cord I heard an unusual knocking noise, and it wouldn't stay running. When I pull the starter cord it is harder to pull than other mowers I have and won't even try to fire unless I spray some starter fluid in the carb.
I checked the crankshaft and it is straight. Any suggestions as to what I should check?
