points or condenser

OK Lads here is a problem that I cant seem to solve so any insight would be greatly appreciated. On my cb360, at idle the R cylinder pops through the carb and pops out the muffler. When the right plug is disconnected it quits. Runs fine on the left one alone. The spark from the grounded R plug is good at anything above an idle but poor to intermiten at idle. I checked the points and the R setdo not arc at all. Whats up here?n is constantly arcing while the L which is good and strong does not arc at all. Could I have a condenser going south on me? The coils are within specs . I mean the R points arc like crazy while the L ones dont arc at all and that cylinder runs perfect. Iterestingly enough it starts and runs pretty good at speed but idles like sh t.
 
Possible bad connection in the plug caps. Popping in the carbs and muffler is a classic lean symptom though (and almost definitely not related to your spark issue). I think it may be time to clean the carbs.
 
Sonreir is right...first thought that came to mind with back firing is a lean condition. Run it for a few minutes and check your plug burn to verify. Cleaning the carbs isn't a bad idea...Also check for any air leaks in/around the carbs. Use carb cleaner or starter fluid. When it gets sucked in the RPM will change (lower for carb cleaner/higher for starter fluid). That'll help you find if any leaks.
 
Well lads the starting fluid was the give away. Immediate rise in RPMs when sprayed on R intake. After I replace (locate first) the intakes I will persue the weird spark issue.
