Still having the reoccurring problem. Once a month I can go out and crank and crank and it will absolutely not hit. Once I go out and pull the fuel line off of the regulator and put it back on it cranks right up. This time I started with the gas cap...pulled it off and it made a little sucking noise but not bad...tried to crank it immediately after that and still nothing til I pulled that fuel line off and put it back on. My sources say regulator is sticking...but why?

 

Anybody?
