locogato11283 Posted April 25, 2014 Report Posted April 25, 2014 Get rid of those carbs and get regular PWK.. That's your problem. Quote
Buffalo-Banshee Posted April 25, 2014 Author Report Posted April 25, 2014 I like to try to make these carbs work before i go that route... sombody has to have some tuning experience with airstrikers Quote
hp2000 Posted April 25, 2014 Report Posted April 25, 2014 Sounds lean to me even on air strikers. Cubs and servals we have ran in my group usually end up with 50-55 pilots and around the 162 main. Sent from my iPhone using Tapatalk 1 Quote
Buffalo-Banshee Posted April 25, 2014 Author Report Posted April 25, 2014 well I read on here the air strikers require leaner jets with some people going as low as 35/145 and they run great. HP2000 are you running at sea level? Quote
hp2000 Posted April 25, 2014 Report Posted April 25, 2014 Yes mostly only ride glamis. Better be rich on jetting when starting on a new motor than blown. Sent from my iPhone using Tapatalk 1 Quote

bluebanshee98 Posted April 26, 2014 Report Posted April 26, 2014 The air strikers do favor a small pilot jet. My buddy's 421 cub does the same thing. Breaks up a little bit before the band but not too bad. Keep us updated on what happens. You may need a different needle but I'm not 100% sure on that. Quote
Buffalo-Banshee Posted April 27, 2014 Author Report Posted April 27, 2014 Well I went for a rip today and its a bit lean at 40/150s cel needle middle clip I may try to start fat at 55/160 Shee ripped 2-3 gear but then fell on her face Quote
hp2000 Posted April 27, 2014 Report Posted April 27, 2014 Cool report back Sent from my iPhone using Tapatalk Quote
locogato11283 Posted April 27, 2014 Report Posted April 27, 2014 Sell carbs. Buy regular PWK. You're going to fight those things forever. Quote
Buffalo-Banshee Posted April 28, 2014 Author Report Posted April 28, 2014 Well maybe if a set of 35 pwks comes up for a good deal I'll try them I don't get why the air strikers are hard to tune... Quote
Buffalo-Banshee Posted April 28, 2014 Author Report Posted April 28, 2014 Well I tried again running 48 158 this time 2 turns on the screw cel still middle clip and still no luck so I think I'm giving up and going the regular pwk route so if anyone is looking for carbs pm me Quote
hp2000 Posted April 29, 2014 Report Posted April 29, 2014 So still lean ? Sent from my iPhone using Tapatalk Quote
