Problem with h/l needles on Walbro carb????

[JayV3rc]

Hey was just wondering if anyone with the 813 Walbro carb has been having problems with the high speed and low speed needles coming loose mine seemed to back themselves way out how often should they be checked cause I never had the problem on my stock carb

I would check them before each run. If they keep backing out, you can put some o-rings under the springs to keep them in place.
