Yes, you can check your crank seals, since that is the most logical choice. Although that U2 stuff is really rough on carburetor's and can get really gummy in under a week.

i drained my carb after i ran it the carb was clean when i took it apart to clean it i was thinking the u2 being mixed for a month may have gone bad I'm going to try some new gas and see and if it still does it the the crank seals may be bad how do you check them with a leak Down Gage

Yep, leakdown. And throw that U2 junk away. I have tested it, and it basically takes you down that last couple jet sizes that you were afraid to run. That is the ONLY reason it makes more powa. If you match air/fuel ratios, it's all the same..... without that smell from hell!!!!
