Running way rich

[bansheezer]

Is it possible that if a banshee is running too rich it would idle but as soon as u hit the gas it wants to die and bog, its spraying oil out of the exhaust all over my garage floor its so rich, i just leaned it out but now i cant get it to start but i was wondering if any of you knew, o and exactly where should the idler screws be set at on a stock banshee

[biggun6ss]

Yes that could happen. Take off your air box lid, take out your filter and look into the carbs so that you can see your slides. Adjust your idle screws so that they both open and close at the same time. Open them up a little and try and get it to run. If you get it running, adjust your idle screws until you get the idle where you like it.

I havea had that problem a few times. I know afew signs of boggin rigth off idle are A) a pluged pilot jet or bad reeds. I would check the intake tract to make sure that everything is working properly. no gaps in the reeds and no sticking in the reeds. make sure both jets are clear. what engine setup are you running. carbs, reeds, cylinder, compression, elevation. so on and so forth. you still have a tors? and are both sides firing the same? usually if the main is too rich you wont feel it on the bottom end. and if the pilot is too lean it will bog.

It is completely stock, it ran perfect until i had to pull off the throttle bodys and replace the idle adjuster screws because one stripped out and one was broken, I put it back together and pulled the pilot screws out so check if they were plugged and put them back in 2.0 turns out like suggested for stock, I think one of them is plugged and also only one of the pipes was smoking the other didn't blow any blue smoke at all, Ill pull the pilot screws tonite and blow them clean and see if that helps, the tors is unplugged also

Make sure you did not get the slides in the wrong carb they are R&L, you should be able to see the cutaway from the air filter side of the carb. JM2C

[bansheezer]

could this cause it too idle to high and not be able to turn it down?

[biggun6ss]

If you don't get your slides in right it can make it idle high. If you put them in, make sure they are not in a bind, that will make it hard to adjust the slides. I did it to mine one time, the cable was in a bind and wouldn't let the slide go down far enough to bring the idle down. I took off the carb top and spun the slide around one full turn, put it back in, and it moved up and down with no problem.

 

You say you turned your pilot screws 2 turns out. Did you mean your air screws?

[bansheezer]

yeah the air screws, that is what it calls for in the manual but ill see if there in a bind and put the needle back to its original position instead of keeping it on the leaner position

[bansheezer]

Well my slides in the carbs were backwards, i just switched them around so the cutouts are facing the airbox, Im not sure where the idle should be at so it wouldn't start by kicking it, i just got a pull down the road and with or without choke it wouldn't even fire so i gave it about have to 3/4 throttle and pumped it a little and it fired on and off, i pulled in the clutch and it revved up high for a second then it just died right after that, i did it 3 or 4 times, i know there is no airleaks cuz i never took that stuff apart and it ran fine before i ever touched the throttle bodys on top of the carbs or the airscrews, everything is how it should be except for the idle screws at this point so i dont really know what to do, i turned the idle up and down and it just did the same thing, any suggestions? o and it also backfired once a little bit, the compression read 100 psi in both cylinders when i checked it too

bansheezer im having thhe same problem, and i know it isnt the pilots because i cleaned mine right out i cleaned the whole carb, but im stil getting oil out the pipe and it hesitates right as i l et ou tthe clutch and acts like its gonna die, im pretty sure my reeds are good.

[Wicked98Shee]

with only 100 psi i would be doing the top end very very soon LOL

[biggun6ss]

SO you can't keep it running at all?

[bansheezer]

ok i am almost positive i have found the problem, i was told to check my choke tube for leaks and as i was looking i couldn't see it, turns out it must have came off sometime and hopefully thats why its hard to start and has been running like shit, how much should the compression be on a stock banshee? it has never been touched and its 16 years old but it doesn't have a whole lot of hours on it either

[biggun6ss]

Compression will depend on your elevation but 100psi does sound low. If the cylinder walls look good you could just get a new set of rings and hone out the cylinders. But if the pistons are stock I would get me a new set. If you are missing the choke tube that might be your problem. You can just get some more from a auto parts store for really cheap and see what happens.
