Fuel pump Then Cartek!!!!!!
 

Finally getting my Wally 255 next week along with a fuel filter which should take care of my really bad leaning out issues. Hopefully week after that I'll be heading over to Cartek to get my tune so I can go fast :):):):):)

I just had my 2nd walbro go bad recently, hope you don't encounter the same.

i know a couple people at my school running the same pump with no issues hopefully it'll all work out im more worried about the tune honestly
