I just noticed the post after replying to this one. Also since then I installed the Holley unit mentioned before. After the "steam" clean I checked the timing, went through the initial settings on the Weber for Fuel/Air and Idle then tweaked to my ears and the results were very positive. Easily a 20% increase in power across the band, no hesitation between 2600 and 3k RPM, after letting it idle (high for a bit then adjusted to 650) the unburnt fuel smell was completely gone. Last but not least... no more dieseling. Just my experience and could be totally different for you if you have different gear(of course). Oh, I had the FPR set just under 2.5lb

Good Luck
