Hello,
I'm new in this forum. Living in Finland so sorry about my not so perfect english😅.
I recently picked up a -90 250 quadracer. Mikuni tmx 38 carburator, large foam air filter(no box), HGP silencer and do not know about the exhaust. It looks like an original.
Problem is that it wont idle and wont rev also. Have changed the plug, cleaned carb 3 times. I Cannot see any numbers on jets. Not main, pilot or jet needle either.
Does anyone have experiences about those mikuni tmx 38 carburators? Jetting suggestions? Or what else could be wrong. Compression is fine(tested), powervalve seems to be working well etc. Have not tested air leaks yet.
