sootman73 Posted August 8, 2011 Report Share Posted August 8, 2011 So i took my banshee out yesterday and after one lap around a pond it was running on only one cylinder. cant kick start it must be pull started and then its only one cylinder still. pulled plugs, junk but cleaned them and swapped them side to side. still the right side wont fire. inspected the wire and my buddy checked spark while i kicked it. went all the way up his arm to his shoulder. so i have spark and i just got done cleaning the carbs. my plan is to perform compression chekc, pull and inspect carbs, pull reeds to see if i can find any damage. If the carb is just that dirty or something then i'll clean and install to try it again. hopefully the lap around the pond on powerband didn't hurt anything in the motor. the passenger side pipe still smokes so there was still fuel and oil getting into that side but its the heat difference cylinder to cylinder that worries me.... what do you guys think?

mysterion Posted August 8, 2011 Report Share Posted August 8, 2011 choke tube. It connects the 2 carbs together. Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted August 8, 2011 Report Share Posted August 8, 2011 What did right plug look like? Swap plug wires side to side see if changes. Quote Link to comment Share on other sites More sharing options...
sootman73 Posted August 8, 2011 Author Report Share Posted August 8, 2011 What did right plug look like? Swap plug wires side to side see if changes. both plugs were pretty fouled but we cleaned them up and swapped them side to side, still no changes. I will try that Quote Link to comment Share on other sites More sharing options...
Man-O-Steele Posted August 8, 2011 Report Share Posted August 8, 2011 Check to see if you hav the carb slides in the correct carbs. I had minne backwards and it did the same thing. Quote Link to comment Share on other sites More sharing options...
sootman73 Posted August 8, 2011 Author Report Share Posted August 8, 2011 they are in the right carbs. i never take both slides out at the same time. i take one carb off, disassemble, clean, reassemble, and install. then repeat for the other one. im gonna get new plugs and do a compression check. we'll see what happens.

BansheeBoy347 Posted August 8, 2011 Report Share Posted August 8, 2011 I had the same promblem once before and come to find out. I had burned a hole in the top of my piston. Quote Link to comment Share on other sites More sharing options...
sootman73 Posted August 16, 2011 Author Report Share Posted August 16, 2011 Put new plugs in it and got it running on both cylinders most of the time now but no power and i cannot start it by kicking unless i spray a little brake clean into the carbs. im gonna pull the carbs off and inspect them to see if there is dirt in them again just to make sure. whats the next step after that then? at the same time im going to re-pull the tank and see what i can see into the spark plug hole. how much do i have to replace if i pull the head off? eg bolts, gaskets, anything else?

sootman73 Posted August 16, 2011 Author Report Share Posted August 16, 2011 okay ill do that i completely forgot the compression check Quote Link to comment Share on other sites More sharing options...
DuneBooZeR Posted August 16, 2011 Report Share Posted August 16, 2011 okay ill do that i completely forgot the compression check Did you ever check that choke tube was connected like mysterion suggested? Because the same thing happened to me also. Quote Link to comment Share on other sites More sharing options...
sootman73 Posted October 6, 2011 Author Report Share Posted October 6, 2011 Got a compression check on the left side and could only manage 70 psi. throttle all the way open and did it like 5 times cause i couldn't believe it was that low. last time i checked it was 110 what should i check next or should i pull the top end off?

traxx2003 Posted October 7, 2011 Report Share Posted October 7, 2011 get a different compression tester ive had a motor that is running good and last checked had 145psi and the other compression tester only read 40 got a new tester and it read 145 again I had a similar experience with mine, but mine would idle fine. But at soon as I rev up the engine, only one cylinder would accelerate/fire. Come to find out, the retainer clip that holds the slider needle on the right carb had come off, so even though the slide would move up/down the needle would just stay in its idle/down position, thus starving the right cylinder. I also did a compression test on mine and I had 120psi on both cylinders. Hope is nothing serious. Quote Link to comment Share on other sites More sharing options...

What was compression on the right side. Way more? If so, I would say that you need a top end rebuild. Quote Link to comment Share on other sites More sharing options...
