Once in a while when I hit a jump wrong (not a hard hit, just a small one will do it also) there is hardly any power at all. The car will move but just barely. After 10 or so seconds it will start working correctly again. Then I take a jump wrong or jar it in some way and no power again.

I have had a couple of guys that are good at tuning try to figure it out but they haven't had any luck so far.

It does it in two different vehicles with different clutches, etc. We have done an air leak test and it doesn't appear to be leaking anywhere. We have went back to factory settings a few different times and re-tuned and it still does it. The carb doesn't appear to be sticking closed.

Has anyone seen this happen before?

Thanks!!
