The guy that did my 1050 said most of his redos of carbs that were started to be converted to E85 were started with the Quick Fuel conversion. I would send it to a carb shop that does E85 carbs. Why do I know this is because I had to have mine totally redone. Give me a PM and I will give you the guys name that redid mine.My carb came back and it was spot on at idle and just a bit lean at WOT. Alot more has to be done to a carb that is not in the kits you buy.
