So I replaced my 1704 that was leaking gas after shutdown with a new 600 and found that I still have the same problem. I also had dropped the float level downfrom 7/16 to 1/2" with no luck.
I guess I dont understand that I am running between 160 and 190 temp, how the carb can get hot enough to boil the gas like that. My egr cross overs are blocked off. I am running a 2101 dual plane with headers. I am going to order a 1" phenolic spacer tonight and see if it solves the problem.
