Hi im new to blasters but i just bought n 03 blaster that has n LRD exhaust on it n its bored .02 over n im wondering wat a good fuel/oil ratio is good for this cause i don't wanna run too lean and blow it up. (and yes the oil injection was shut off) The guy i got it from said he thought he put in 40:1 n it wouldn't wanna idel very good when not warmed up but when ya drove it for a minute it would just rip. Any help would be appreciated
