RE: YS53 problems
Hi,
I had a good look around the motor last night, removing the main needle seat. There was a ton of crap in there, including a chunk of silicon fuel tube - lord only knows how that got there! It could quite conceivably have been intermittantly blocking the fuel passages. Adjusted the tappets - interestingly the only wear seeming to be on the inlet side.
A quick test run and she's back to her best!
Can you tell me where I can get the needle o-ring. Novody over here seems to have them.
kind regards
Julian
