could the needles be bad if so where can i get some new needles and an oring for the carb. also what are the factory settings for the needles
Dear Ryan,
I went to test the .28 this afternoon and would like to find what trouble you have. As my experience when the engine still new,it do have the same situation that you have. It is not leaking problem. Please back to the rich setting. And run some tanks of fuel. Lean the main needle 1/8 turn between each tank till the high speed is enough. Another way is that you can add 0.1mm head shim to lower the compression.
How to check if the break-in process is finish? Take out the plug and pull the pull-start system. It should be very smooth after break-in.
Regards,
Dino
