Thanks to everyone that helped me with this, I have finally got the weber running quite well I have ordered a few more jets but I end up with this with what I had around:-
Primary main-132
Secondary main-140
Primary air correction-170
Scondary air correction-165
Primary Idle-55
Secondary Idle-50
NOTE:- This carby has no choke or choke plates they were removed a while ago (for a gain of about 3cfm)
Seems to run very well even when cold, its a prick to start but once running, it will Idle slowly after a few minutes of reving at 1500rpm.
I set the timing at standard 6deg (1990 Brumby ute).
anti back fire valve and reed valve are disconnected.
The carby changes the sound completely, The enginge revs quicker and smoother, Still a few flatspots though mainly at quater throttle and i thnk it could use a larger secondary main for the top end isnt much different to the old carby. When jets arrive will play and post results.
