I had a problem with the engine missing when the throttle opened and after stripping the carbs, I have found a tear in one of the throttle piston rubber diaphragms which was probably the problem. My question is twofold.
1. Were is the best place to get a new one from? Ebay looks pretty bare!!
2. when i took the piston jet needle out, there were two very small washers located there. I cannot remember whether they were above the circlip on the needle or below. Anyone know. I am pretty certain they were above but wanted to confirm.
The best place is ebay, i waited months to get a good one, i had a look in the manual and couldnt find ref of the washers, if you tell me you email i can send you the pics telling you how to strip and clean the carbs.
