Brand new 48cc Grubbee Skyhawk still isnt running. I replaced the stock plug with a champion E3 Diamond fire plug. I closed the gap to .020 as suggested by other troubleshooting threads. It fires a lot more and is very close to starting. At this point I'm lost as to what i should do to get it running. The best guess that i have is that its a carb problem. If you have any suggestion as to what i should do please say something. Thanks!
