thx for responding.i didnt know wd-40 could be used to clean carbs. i checked all the lines,fittings etc. and all are fine.i have a can of compressed air (for blowing out crap from keyboards) with a small tube attachment.im going to remove the needles,grab some wd-40 ,and clean them,then blow them out to see if that makes a difference.the starting system is the tiger drive that comes with the boat.
