trex banshee Posted July 29, 2005 Report Share Posted July 29, 2005 hey guys i need some help with my banshee. it idled fine last year never had to give it gas just kicked and fired. since then i have have advanced the timing 4 degrees, took 12 cc domes out and put 8.5cc's in, and went from running 91 to 111 octane gas, and sst's to rockets. now you have to give it a little gas for it to start and even when it is warm it will only idle for maybe 10 seconds. so i dropped from a 148 pilot to a 142 and not a whole lot of change. i am running 140 mains with 35 airstrykers.

racer Posted July 29, 2005 Report Share Posted July 29, 2005 all of that extra compression may not want to let it run at low rpm levels. have tou tried adjusting the idle screws at all? Quote Link to comment Share on other sites More sharing options...
trex banshee Posted July 29, 2005 Author Report Share Posted July 29, 2005 yeh i have got the idle screws up as high as they will go. i was told by someone else that they get really temper mental with high compression and won't idle.

Dunsmoor86 Posted July 29, 2005 Report Share Posted July 29, 2005 What is your comp.? If its way up there you are going to set the idle pretty high up there to keep it running. More like an 1/8th throttle idle. thats my opinion anyway think diffrent? Quote Link to comment Share on other sites More sharing options...
Rare Scottish Tree Badger Posted July 29, 2005 Report Share Posted July 29, 2005 You might find that with your improved cumbustion design, you may not need as much advance as +4 degrees for best performance. ... That will also help your idling problem. Rare. Quote Link to comment Share on other sites More sharing options...
wesw Posted July 29, 2005 Report Share Posted July 29, 2005 try going up on the pilot, sounds like it needs fuel Quote Link to comment Share on other sites More sharing options...
trex banshee Posted July 30, 2005 Author Report Share Posted July 30, 2005 well if it was being starved of fuel on the pilot (being lean) wouldn't it make the plugs white. mine are pretty black nice and rich but its not too rich its just where i like it just not idling. so with higher comp. i don't need the timing advanced so far? thanks for all the help.
