i have a strange occurance happening and i can find any posts that can help. i have a 1998 slxh 1050 ive had it a year or so and have performed alot of fixes on it but this one has me stumped. one of the cylenders i believe the pto will puff or burp if you will everytime i hit a decent wave it gets up and runs great cruises fine and this only happens if i hit a wave. all the spark plugs have the same color so it doesnt appear to be running lean. i have replaced all the fuel lines in the past and cleaned the carbs last fall i have had the carbs on and off a handfull of times tho is there somthing i could of missed. everything apears hooked back up propery like i said ski runs like normal just burps if i hit a wave any help would be appreciated i hope im describing this well
