Lmao.... I cant burn Frankenturner now gasps* its to shiny! I will just wait until the kirby inevitability blows its self up!

Ok will try that again give it a spray and try sucking it through again...

Btw The check valve is fine it pushes down and back freely and smoothly....the reference was for a ball bearing under that it is fixed in the gallery it sits in, just like the outer ones....just pathway blocks I thought, but wasnt sure of its relevance with my issue. ..

Unfortunately idont have another mate...got a few early carbs and tanks but i dont have the throttle bracket to go with them, and they dont slip under the current throttle linkages....i will try and get one temporarily on just to try....

Thanks mate , ill give it another flush and try and cup the intake a few times while its running and see if that loosens it

Cheers Grumps...ill let you know if it works or unauthorized images if it burns!
