I’m working on getting a roadside find free LX188 up and going again (link here (Roadside Find LX188) I’ve replaced the carb, one coil that seemed to be bad and both spark plugs. When I first tried to start it the carb was puking gas out of it. I put a new carb on and it started fine but smoked and smelled a little gassy. Pulled the plugs and the left one was wet. Installed new plugs and it ran the same. I tested the exhaust pipe temperature on each side with a temp gun. The left side is noticeably cooler than the right by 100° or more. I borrowed a coil from my 345 and the exhaust temp improved but still less and the smoke went away. I ordered a new coil and have that installed and it still is running much lower exhaust amp on left side.
Ok so now my question- is it possible for the igniter to go bad on one cylinder and not the other? Can it partly work on the one side, where maybe a weak coil wouldn’t fire very well? I’ve read some info on testing the igniter with a spark tester, I’m going to try that today and see what the results are from that test.
Next step will be to remove the rocker cover and check valve clearance. I have new gaskets for those on order so I’m waiting until those come in before pulling the cover. I would think improper valve clearance would cause backfiring or some other symptoms?
