I agree with your opinion of the LHS. No one there talks with any degree of certainty. They all sound like they atr just reading off the cover of whatever product you are looking for.Knowledge is sadly lacking. But they gave me an answer I had presupposed to be correct so I went with it. I shoulda checked here first.
I have tried 11-7, 12-7, 12-8. Afterreading the OS site I think I will go with either the 12-7 or8. Or the 13-7 or 8.Currently running the 12-8.
Yes the fuel tank and lines are all new.
I will be getting home around 7pm central usa time. so I will look at the carb then and try this all over again. I will keep you all posted later this evening.

Fuel tank is 12 oz. I do not remember which plug the LHS`sold me. I'll check that when Iget home. Thanks fellas.
