my paddock basher had a little screen blocked up where the fuel line screws in, mainly because i was using a bit of rubber hose to extend the fuel line, and well wasnt made for fuel i couldnt even get to 70, went allrigh but once it got to jogging pace she stalled suprisied me it still ran i reckon half the rubber hose was in the screen, this was on a 202 with varajet
