Cubshee421 Posted January 4, 2015 Report Posted January 4, 2015 I have a 421 cub on 100LL the main and pilot are dailed. 160/48 The issue is if you rev it once its fine but if you rev it again it makes a bogging sound out of carbs. 39. Pwks DGH neddle in the middle. Do CEL wirk good on cubs. Shearer sb/oof Quote
RadarRacing Posted January 4, 2015 Report Posted January 4, 2015 If it boggs off idle or wants to die. Richen the needle position. If it is like a rich bogg as well as having to clean up smoke , lean needle position. DGH is often fine, 160 is usually about 3 to 5 jet sizes lean for our elevation at 1300 ft. Quote
sleeper06 Posted January 4, 2015 Report Posted January 4, 2015 I was just about to say that bitch is lean , that set up round me would be at least 172-178 range on a perfect chop but av gas does have a different gravity than my usual vp I'm no expert with and I'm not a big fan. Pilot usually 50-55 depending on porting and reeds, dgh usually tunes out fine for me but I have used cel on more dun able set ups Quote
