Hey Grump
Mate thankyou for your advice
I,ll strip n recheck the carby again
Do you think that the squar slot in suction tube where main jet screws into being about twice the oridginal size could be a problem
should there be a gap between the end or that tube and the bowel when the main jet nut is tightend
I wonder if my eforts to repair the damage to the tube with the plastic sleave has resticted fuel intake to main
ill try to check that as well
the old thing came up nice with paint black motor red coweling n fittings bare alloy carb
