Mason Posted April 21, 2009 Report Share Posted April 21, 2009 (edited) i finally got my rebuilt left carb back from my stealership. i put it on and started it up and it idled high, but im not worried about that at the moment. the right carb now leaks when sitting there just idling, but im not worried about that at the moment, either what my major problem is, is that my left cylinder wont fire until i rev it into the powerband, and when it does that, it burns all the gas/oil dumped in the cylinder, and smokes like crazy. it runs fine when its in the powerband, but when its out of it or idling it wont fire and will not roll when its not in the powerband. it gets fuel and it sparks when in the powerband, im just so confused with it i dont know where to start. the right cylinder sparks good and is what keeps it running. i took it out riding and it sometimes would randomly spark and kick into the powerband and almost made me lose control twice. im just afraid that without any spark in the low end/idle it will hurt my engine. if anybody has any clue or info on why this would happen please let me know. i have been plagued with problems ever since i got it, it is kinda sorta starting to turn into a downer Edited April 21, 2009 by Mason Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted April 21, 2009 Report Share Posted April 21, 2009 If you are worried about it hurting it your motor you really shouldnt ride it like that, until the problem is solved. I would check for spark, check spark plug boots and coil. Make sure you dont have a bad reed. Clean the carbs out really well, make sure none of the jets are clogged. I had this prob one time and it was bc my stator was going bad. Good luck, Im sure more will chime in with some more ideas for ya. Quote Link to comment Share on other sites More sharing options...
Keyser Soze Posted April 22, 2009 Report Share Posted April 22, 2009 (edited) Check your gear oil, could be a crank seal. Edited April 22, 2009 by jugriggs Quote Link to comment Share on other sites More sharing options...
AWR Posted April 22, 2009 Report Share Posted April 22, 2009 are your carbs synced?? Quote Link to comment Share on other sites More sharing options...
Mason Posted April 22, 2009 Author Report Share Posted April 22, 2009 when i said that i took it for a ride, i pretty much took it around my yard twice and didnt want to do any serious riding with it. as for spark, i switched the caps and plugs with 3 new plugs and both times it would only spark in powerband. now when i left it run the gas out of the carbs before i put it away they both started firing right before it totally ran out of gas. my left carb, the rebuilt one, is spotless and i had the float properly adjusted and works good. the right one could probably use a cleaning but the float is properly set and works fine. what does gear oil have to do with spark? i really don't have a much knowledge on 2 strokes, im more familiar with 4 pokes than anything Quote Link to comment Share on other sites More sharing options...
millertime Posted April 22, 2009 Report Share Posted April 22, 2009 first off you need to fix the carb that is leaking gas !!!!!!! when it is leaking like that, the needle is stuck open there for it is flooding that cylinder.. won't run tell it burns all the fuel dumping in the cylinder.. get that fixed then report back Quote Link to comment Share on other sites More sharing options...

fastbanshee8 Posted April 22, 2009 Report Share Posted April 22, 2009 Check the gap between the flywheel, and the pick up coil. You should be able to slide a match book cover between them, and that's it. Also, it might be a good time to replace both spark plug boots, they're cheap, and easy to replace. Try those two things, and let us know. Quote Link to comment Share on other sites More sharing options...
BellicoseBanshee Posted April 22, 2009 Report Share Posted April 22, 2009 what does gear oil have to do with spark? i really don't have a much knowledge on 2 strokes, im more familiar with 4 pokes than anything If the right cylinder is smoking excessively, it is a sign that the PTO crank seal is failing, for the engine will pull gear oil into the crank cavity and then burn it. The few times I have seen an engine burning oil due to a bad seal, it was very obvious because the smoke had a very distinct "burnt gear oil" smell.

millertime Posted April 22, 2009 Report Share Posted April 22, 2009 is the hose that goes in between the carbs on ? the one for choke on the right carb ? Quote Link to comment Share on other sites More sharing options...
Mason Posted April 23, 2009 Author Report Share Posted April 23, 2009 ok heres the lowdown of it now: i took the cover off to look at the flywheel. the timing plate? that hangs out over the right side of the flywheel is just big enough gap to put a matchbook in between the flywheel and the plate part, everything is connected to both carbs, i took apart the spark plug boots and cleaned/degreased them, put them back together. it still isnt sparking, i have ran out of ideas and im starting to think i traded my pristine warrior for a lemon of a banshee, i have dumped alot of money into this already and its getting kinda tiring. the right exhaust does not smoke, the right side is the one that is running fine, but it is also the right carb that is leaking gas out the overflow tube. the left one is the one that dramitcally smokes when it decides to spark (when it hits powerband and finally sparks) and will smoke for a little until its burned what its burning or i left go of the throttle and it drops out and stops sparking. im so disgruntled with this thing that i broke down and am going to take it to the stealership tomorrow and let them screw with it. im going to let them resync the carbs and left them try and figure out the problem, Quote Link to comment Share on other sites More sharing options...
BellicoseBanshee Posted April 23, 2009 Report Share Posted April 23, 2009 You are right, you did say the left side is smoking, sorry... I guess I am getting old... Quote Link to comment Share on other sites More sharing options...

shee4speed Posted April 23, 2009 Report Share Posted April 23, 2009 sounds really all you need to do is sync those carbs properly.And get it jetted right. Quote Link to comment Share on other sites More sharing options...
