jbooker82 Posted September 30, 2009 Report Share Posted September 30, 2009 I run cel's in my pwk33's with a fast dune ported 4 mill with cpi pipes. 45 pilot and a 155 main at 2200 ft. Quote Link to comment Share on other sites More sharing options...
Dinner Posted October 1, 2009 Report Share Posted October 1, 2009 When I switched over to CEL's on my 33's there was quite the difference on how the engine ran (a good thing). Once the needle clip position is put to the right spot, these carbs run real nice Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted October 1, 2009 Report Share Posted October 1, 2009 I believe cgl's same taper and diameter just but the length is longer. Here is a good write up on keihin jetting. It expains the needles funtion really well. http://www.duncanracing.com/TechCenter/KeihinCarbJetting.pdf Quote Link to comment Share on other sites More sharing options...
