What do you mean stupid? 87 89 90whatever unless you got some serious mods you shouldn't really notice that much difference in the performance between redily available octanes in pump gas. more likely a coincedence. timing; rich fuel mix; jets in carbs among other things can cause back firing. run the tank off or drain into yer mower and put in summpin else if it gets right again blame it on the gas if not the GAS didn't break it somthin else just got screwy good luck bro
