i have 12a bridgeport i have a 45 weber im having problem getting it started it starts but it wont idle the jets are 145-200 at 4psi the engine is rebuilt

 

Welcome to nopistons! I'm moving this to the 1st generation section, you should get more answers there.

 

is it high idling or just dying? 4 psi seems a little low to me.... if you hold down on the gas after it fires will it stay running? just need a few more details

 

its no idle at all its not bacuum leak it will keep running at over 2000 with foot pedal other wise it dies i think is the weber it was used on a 13b periphera as far i coud see the weber its been drilled and big chokes im shopping for weber 45ida original setting

 

You may need to go up one or 2 sizes on your idle jets. If you have to open the butterflies too much then it is falling out of the idle circuit.

 

thanks ill buy different jet sizes ill order them from racing beat
