I have the same motor, but dont have a answer.. tagging along for one..

What happened for you to pull the carbs.. >? This engine is a beast and just wants to run....The more I run it the better it gets..

captain dave,my motor had a low idle miss,it was sneezing at idle when i put it up in feb. tracked down problem to top carbs,removed and cleaned,ran it hard last night ,runs like a jem,these motors weakness is the carbs,i do run a racor 10micron,but ethanol has been a little problem,my first motor a 1989 175 yam,needed the carbs done once ayear ,after that no problems
