lonestarxp, Do you have a temp Gage? one of the inferred ones? you need to check the temps. I found that the carb is getting too hot, Simply cut the scale carb opening in the front of the cowl. this will let air in around the carb and cool it off. Gas goes to vapor at a round 120 deg I took a carb temp last year at 105 deg in October. I started asking around. All the TOC guys have the fronts cut out of the cowls. In short the readings are 10-20 deg above the outside temp. Once we start flying around here again I'll post some temp readings. The cylinders can handle higher temps (250, 300+ not recommended) As long as it's not lean. Too lean will do one in in a hurry. I try to keep mine around 180-200deg. If you want pics of my set up let me know.

As for the 3W vs DA thing, Lets just help with the problem. O.K. guys?

Later, Scott
