Weber 45's & starlet distributer info

[megabob]

Hi,

Ive got a 4-AGE which has been setup to run on carbs.
previously it was on Mikuni's but they needed a rebuild and parts are getting harder and harder to find so i went with a new set of 45 Weber's.

I can get the engine to run but it is very hard to keep alive and is popping quite alot from the carbs could this be something to do with the jetting or more to do with the timing of the dizzy?

The current setup of my Weber's are:
CHOKE - 36mm
AUX VENTURI - 4.5
EMULSION TUBE - F16
MAIN JET - 140
AIR CORRECTION JET - 175
IDLE JET - F11/50
PUMP JET - 35

This is mainly based on the "Carburetors for the 4A-GE" in the reference section but this i think that was for a Weber 40 not a 45, will this make a difference?

If anyone have any info on a better jet setup for a stock 4-AGE if this might be cause.

Thanks
