my typhoon 50 is getting no fuel.the plug is dry after crankin engine.i have cleaned out the carb.if i take off the vacuum pipe and suck petrol will eventually come thru but i have th suck the pipe really hard.any ideas what it could be?
Sounds likes a duff tap, but make sure the vacuum pipe isnt cracked or split anywhere as you could be loosing vacuum making it seem harder to get fuel to flow...
