Gikki44 Posted October 31, 2010 Report Share Posted October 31, 2010 The left side cylinder isnt firing correctly. It takes a bit to get started then when it does it idles fine for a few seconds then starts popping and carrying on on the left side. I have checked pick up gap, tested stator and pick up coil. All are good. Put new spark plug caps and tried switching caps from side to side and still the same thing. The carbs are synced but it seems like its running out of fuel then just dies. It wont hit powerband worth of shit it feels like its just holding back so i guess it would be because its probably running on one cylinder. Any ideas as to what this could be?

fastbanshee8 Posted October 31, 2010 Report Share Posted October 31, 2010 Have you cleaned the carbs? Make sure the gas cap is venting properly, and check for air leaks on the left side. Quote Link to comment Share on other sites More sharing options...
98_shee Posted October 31, 2010 Report Share Posted October 31, 2010 Do a leak down test to check for air leaks. Make sure the wires from your pickup coil didnt get into the flywheel. Do you still have the tors and ebrake hooked up? When did it start doing this? Quote Link to comment Share on other sites More sharing options...
Gikki44 Posted October 31, 2010 Author Report Share Posted October 31, 2010 I'm gonna do a leakdown test next. The wires are good and it's been doing this since I bought it. Could an air leak cause this. I also notice when it warms up a bit I can see a slight bit of fuel coming out the brass nipple on the back of the left carb. Both carbs are spotless inside as well. The float is not stuck either. Already checked. Quote Link to comment Share on other sites More sharing options...
98_shee Posted October 31, 2010 Report Share Posted October 31, 2010 The brass nipple is an overflow. An air leak can cause it to backfire because it will cause it to run lean. Check your intake boots for cracks. They will crack around the carb clamps and where the crossover tube goes. Is the balance tube in? Its the black tube that goes between the carbs.

Bruce_Blaine Posted November 1, 2010 Report Share Posted November 1, 2010 I had the same exact problem. Try turning your gas off (after it's filled the carbs) and clear it out for a second and then run it. I had the same problem and I thought it was electrical but turns out my float was sticking open.

Gikki44 Posted November 1, 2010 Author Report Share Posted November 1, 2010 The balance tube is in. Ill check the boots to make sure of that. But if i try the filling of the carbs and that works does that mean something is up with the float? And would that cause it to run like this?

Yeah man I thought my left side was misfiring but it was my float sticking. I turned my gas off and ran it and it would stop. I had to get a carb rebuild kit and replace the stuff and it runs great now. Quote Link to comment Share on other sites More sharing options...
Gikki44 Posted November 4, 2010 Author Report Share Posted November 4, 2010 I had the carb apart and it doesnt seem to be sticking at all. Could it still be sticking while its running if its not sticking when i pull it out and move it up and down just fine? Quote Link to comment Share on other sites More sharing options...

Well I know there can be more than one thing wrong with the carb (needle, etc.) But i would try running it with the gas off like i did, if it runs good with the gas off you know then it's something in the carbs and it's not electrical. You may not have the same problem as I did though, but I would give it a try. Quote Link to comment Share on other sites More sharing options...
Gikki44 Posted November 6, 2010 Author Report Share Posted November 6, 2010 Pulled the carb and measured float height. Its perfect and not sticking up or down. It takes a hell of a long time kicking the hell out of it to get started and when it does finally start it just misses and dies and then it wont start for shit again. What else can i do here? i do have spark and just the other weekend it would start easier unstil i noticed it misfiring like crazy, then it started acting like this all the time. Now i cant even get it started and running. Quote Link to comment Share on other sites More sharing options...
Gikki44 Posted November 6, 2010 Author Report Share Posted November 6, 2010 Put the carb back in after fully cleaning it. It actually started on the third or fourth kick but it still just misses and carries on. Now it wont start and backfires like hell on every other kick or so.Any thoughts?
