Hi-had a wasted test day today because of what I assume is a carb problem. Joined track with kart running fine, died on secone corner, does this repeatedly. Runs fine on the stand although on a number of occasions it over-revs without me touching the throttle.
Carb that's on it is about 1 hour old in terms of running time, tried spare carb same problem. Engine has just had full rebuild (F Blue), not sure how relevant that is. Checked all settings, stripped down carb cleaned out etc still same problem. Have checked reed petals and they seem okay. I assume high revving is due to it running lean because of fuel starvation and then cuts out bacause of no fuel. Was very hard to get it to suck the fuel through when I first fitted engine back on kart yesterday as well.
Any ideas anyone?
