Hello and thanks for the add. This is a great forum!
Need help determining cause of engine noise on a 1981 Yamaha G1-A2. I'm not afraid to wrench on anything, but never opened up a 2 stroke/cycle engine. Been in family for about 35 years. Likely due for more than a tune-up.
Cart #J10-0385744, Engine #S215-035744
Engine "clangs and bangs". Sound seems internal to engine, not external
Starts fairly well with some choke, but crank seals don't seem overly worn. Starting fluid sprayed at crank seals changes nothing.
Compression test with a squirt of oil into cylinder was about 115, assuming gauge is accurate.
Much slop in throttle linkage starting at connection to governor.
Motor mounts good.
Carb needs rebuild as gas coming out of overflow port/vent.
FYI: Starter/generator belt damage during power washing.
How do I post a video for you to see and hear this engine?
