Engine starts, runs but sounds like it is missing.<br />Backfires occasionally and will not idle.<br />Plugs are getting good spark.<br />Ran engine and pulled plug wires beginning with #1, then #2. Each of these had an effect on the engine idle. Pulled #3 and engine did not change idle sound as when #1 & #2 were pulled. I suspect something with #3 (lower)cylinder.<br />Could it be insufficient fuel flow to #3? A dirty float bowl or debris in the carb? Am I on the right track?<br />I have a Honda service manual (61ZV300V) on order.<br />Will this show carburator servicing well?<br /><br />Thanks, Glofish
