My friend down the road just bought a Yamaha exciter I think its an 89 but not sure, this thing has 3 choke type levers one is the choke, 1 goes to compression relief valves on the engine, the other one i am puzzled over. There is a small valve with what appears to be fuel line on it on the right side above the recoil rope thats where the cable goes from the third choke lever. Not sure what to make of it have not dug into the sled to much, feels like the crank is binding to me but could be the guy he bought it from filled the engine with gas pouring it down the plug holes. Some people just shouldn't have things, so any help would be appreciated.
Update: crank is bad got this thing started sat there and ran about 1 minute and then locked up never seen a motor lock from 1000 rpms sounded like someone stepped on a dog. still not sure what this third lever is for.
