MatHolland Posted March 15, 2011 Report Share Posted March 15, 2011 .020 over. K and n pods. Toomey exhaust. +4 timing. Cut and milled head with 180 psi in each cylinder. 400ft above ground level. Half avgas half 93. Just got my banshee running. 190 is in it and it's pretty rich. Loads up when I'm trying to warm it up revving it.

Phelps Posted March 15, 2011 Report Share Posted March 15, 2011 serious guy? your above sea lvl not ground level unless that shee has wings and do you not see the thread that has everyone's jetting listed? look through it, find similar setups, similar sea lvl's and figure it out. i wasted more time than i really wanted to telling you to do your own research.

MatHolland Posted March 15, 2011 Author Report Share Posted March 15, 2011 Don't be a little mouth bitch sea leve is the same as ground level I'm on my phone jerk off. The banshee has never runright since I got it I was making sure it wasn't another problem I just split the cases. Thanks for your smartass comment go fuck yourself.

MatHolland Posted March 15, 2011 Author Report Share Posted March 15, 2011 (edited) whoops, yes I do mean 290's..ive tried 290s, 270's, and 310s...and its running like shit still...im thinking it might be reeds..its got a new stator, carbs have been went through...fresh top end, new crank seals..and it still falls on its face...now that I have took it down the road, the plugs are bearley getting any fuel...idk what else it could be..ive tried everything...thats why I was making sure that I was right around where i should be on jetting Edited March 15, 2011 by MatHolland Quote Link to comment Share on other sites More sharing options...
Phelps Posted March 15, 2011 Report Share Posted March 15, 2011 pretty sure ground lvl and sea lvl are not the same... Quote Link to comment Share on other sites More sharing options...
BUILDER Posted March 15, 2011 Report Share Posted March 15, 2011 With your setup and being at 400 feet you should be up around the 310 to 330 range so if it running fat with 290's in it you have got something else going on. Quote Link to comment Share on other sites More sharing options...
MatHolland Posted March 15, 2011 Author Report Share Posted March 15, 2011 It was running rich around idle trying to warm it up..i adjusted my air screws, put new plugs in her, and took it down the road running like shit..when i got back i pulled the plugs and both look almost brand new still...no power what so ever Quote Link to comment Share on other sites More sharing options...

Try some 310-320 mains, needles on middle position, 27.5 pilots, and air screws 1.5 turns out. If you burned it down the street at WOT then pulled your plugs and they still look new, you are probably lean or have other issues like an air leak.

MatHolland Posted March 15, 2011 Author Report Share Posted March 15, 2011 something i think everyone is missing is i have had to put gas in a squirt bottle and open my throttle wide open and spray gas so it hits the reeds to start it..ive had to do that twice..once last night after i got it put together, and once today when i tried starting it for the 2nd time. Could that be bad reeds? I am pretty positive its not an air leak...it did this before i put a new top end on it, and split the cases, and its doing it now..i used scotchbrite to clean of every little bit of the gaskets, i know it sealed fine..im thinking the carbs are messed up, or reeds are messed up...and i took it down the road with it sputtering and running like crap. i got 310s in it now and its no different that 290 was.

fastbanshee8 Posted March 15, 2011 Report Share Posted March 15, 2011 If you are having to squirt gas in it to start it, then it's lean. You either have plugged pilot jets, your pilots are to small, or you have an air leak. Check your float levels to make sure they are adjusted to the right height.

gotta_goatsfast Posted March 16, 2011 Report Share Posted March 16, 2011 So you did a leakdown test when you rebuilt it, and that passed I take it? This is how you know it does not have an air leak? Because, it sounds to me like a definitive symptom an air leak will cause. Its running way lean and your jetting sounds fairly close compared to the symptoms. Do a leakdown test and clean out the carbs. If you really do suspect your reads to be the problem (which I don't really think so because squirting gas down its throat wouldn't temperarely cure a bad reed petal) then pull the reeds out and pull them up about 1/8 of an inch and watch them snap back. IMO if they stay lifted off of the block more than 0.010" then I replace them. If its less than that, the positive pressure in the crankcase will surely close those reed petals tight. Also, what is your pilot jet currently? Needle and position of the clip? And lastly, ground level is different from sea level. If I'm standing on the top of a hill next to the beach by the ocean, the ground might be 30 feet higher than the sea. Now if I was on a mountain...

Boosted GMC Posted March 16, 2011 Report Share Posted March 16, 2011 (edited) Make sure you did not switch you'r float bowls. The LH float bowl has a passage that feeds the starter jet and supplys extra fuel when the choke is applied. I switched mine when I cleaned the carbs and had a hard time starting it when it was under 50 degrees. Try a 330 main needle in the middle position and a 27.5 pilot jet.
