I did a search but couldnt find anything out. When i run at night my crossover is putting out a blue flame. Is this normal or what should i fix?

Only at night?

what diff would that make. u on crack.

Just making small talk.

quack i first would ck the plugs see if they are a choc. brown. a blue flame could be a sign of a rich fuel issue. ck ur choke. is ur carb clean. float setting. is ur jetting to rich. also a blue flame can be a sign a valve issue reset ur valves and do a leak down test. a bad exhaust leak. that seems to show up at a wide open throttle to a closed throttle more so than a constant wot. if all else fails do as pod and camo do put in $10.00 plus spark plugs.
