Ok so here is the situation. my 73 cb350 twin was running great, I was on my way home from work and the left cylinder (#1) stopped firing. I took it too my buddy because prior i had some issues with it stalling when coming to a stop. he adjust the carbs and got the the bike to idle at 1000 RPMS and it stopped it from stalling. After a fe days of riding my left cylinder craps out again. I figure maybe since the old plug was so carbon fouled I should just change it out, so I do that and I am off. Last night I am riding and it does it again. This morning I pull the plug out expecting to see a black fluffy mess, instead it smells heavily like gas and looks to me like an oil foul. It is black and wet, and it makes me sad. Where do I go from here?
EDIT: Also I pulled the plug put the cap on and started the bike while holding it near the cooling fins and i was getting good spark. I am new to MC mechanics and I am at a loss.
