Re: Dieseling after MC2100 install
A higher float setting is richer.
Best thing is propane, next is starting fluid, but Gumout carb cleaner works. Many carb cleaners aren't volatile enough to work, they are like spraying water.
Try revving it to about 2500 - hold your hand or a CLEAN rag over the top of the carb to choke it off. As you choke it if it increases RPM just a tad, it's fine - not too rich, not too lean. It it rases up much, too lean. And if it just tries to die without a tiny increase first, too rich.
If the old carb was way rich, it may just be carbon in the cylinders - add a couple cans of Techron to the gas tank. It'll burn the carbon out safely.
