brumby carby flooding on start up
Hi every morning brumby 1992 runs fine for a minute then floods carby. Additional info- fuel filter on firewall is always empty after sitting over night but fills immediately engine cranks over- carby hitachi has been rebuilt by carby specialist at Underwood Qld. Once carby floods and then allowed to sit for a period it will start run rough/horrible until excess fuel burnt off then run and start fine the rest of the day. It has the auto choke set up no modifications to any engine or ignition bits- stoke standard. This is doing my head in as it only happens in the morning first start. Any help would be much appreciated. Have been through old threads but can not find any solution so far.
