gunner6262 Posted May 22, 2010 Report Share Posted May 22, 2010 (edited) ok so i was doing a rebuild and had some issues with a leaking case. resealed the case and did a leak down test and passed with flying colors. throw the motor back in and i was still having issues. im kicing and its not starting. i have spark and the plugs are wet. well anwyays i pulled the plugs and poured some gas down the holes and kciked and it fired up. ran nice and strong but once let off the throttle it dies. try kicking it again and it wont fire unless u repeat the process. we did it again and it fired up and this time we noticed it was runnin on one cylinder. spark was shooting out from the boot and all over th head like the spark wasnt bing delivered into the combustion chamber.i thought maybe it was a bad plug but we switched them and was still on one same side. then i switched the wires around and it started sparking out of both boots. it is really weird i cant think what would cause it. its a new coil pack and the wires are fresh and so are the plugs. its very puzzling any ideas? also it wont fire without pouring gas down the holes. is this cause of that spark issue? seems like if i fix the spark it might run correctly. cause when it fires it runs great until u let off the throttle. any ideas is much appreicated. i really dont think its carbs. they are cleaned and adjusted right and synced so please dont tell me carbs lol. i dont think that would cause spark to shoot out like crazy in a weird fashion.

pr0blumz Posted May 22, 2010 Report Share Posted May 22, 2010 I assume they are stock carbs. Is the choke tube connected between the carbs? Are the slides in correctly? I just had to ask. Quote Link to comment Share on other sites More sharing options...

I just had to ask. not stock carbs 28mm pwk choke crossover???? only thing i have is the dreaded boost bottle but there arent ripped or cracked boots but i will be getting rid of that soon. and yes slides are in correctly they can only go in one way.

newfierider Posted May 22, 2010 Report Share Posted May 22, 2010 (edited) hey man im pretty new to this site and the banshee, but i had this same problem with my banshee, it would only start with a prime through the plugs and wouldn't idle after i let off the gas, and the choke tube that connects both carbs were missing, i replaced it and adjusted the idle screw and she fired up and ran perfect,, but mine never had the same spark issue as yours,,, hope you get her runnin right dude,, best of luck!!

blowit Posted May 22, 2010 Report Share Posted May 22, 2010 how did you clean the pilots? Did you adjust the air screws to no more than .5 turns out? You obviously are not getting fuel in the engine. As far as the spark issue. Reterminate means cut ends off, re........end them. High voltage leaks when there is a breach in the insulation.

AKheathen Posted May 22, 2010 Report Share Posted May 22, 2010 make sure you get some good plugs, not that champion or autolite crap, those like to break and leak spark. ngk is what you want......the "8"s..............and, weak spark will change the jetting, so fix that first.

AKheathen Posted May 23, 2010 Report Share Posted May 23, 2010 when you get it sunning, does it spit back allot through the carbs, or 1 carb? have you tried swapping float bowls? Quote Link to comment Share on other sites More sharing options...
