My RX10 has fresh rings. and seals. and carb rebuilt, and blah, blah, blah. It can not get to full RPMs. I've tried adjustment to the slow and main needles. I also tinkered with the linkage between the carb and timing advance. Slow speed runs great.
Any ideas?
I'm not familiar with 2 strokes. The rod bearings seem to have excess play and I believe the crank has been balanced. There is also ample brown goo that stuck the rings to the pistons. Please have a look at the video and give your opinion. Thanks...
