Mikuni 13b 6port
#1
Im new to this forum and hope someone can help. I have an 88 SE with a 13b 6port, Mikuni sidedraft, Racing beat header and presilencer, N1 mufflers, Centerforce clutch, and Accel 8.8 wires. I recently removed the EFI and installed the Mikuni 44 I was having trouble starting it so I sent it out for a complete rebuild. I got it back and it starts every time. I can get it to idle good but, the throttle response is horrible if the pedal is pushed quickly. I have the manual and found that the screws on the back of the barrels only tune the idle and everything else is jets. The car is running lean and I dont want to blow it up. Im using a holley blue fuel pump and holley regulator delivering 3 psi of fuel. Does anyone know the correct jets for the 6 port motor? The jets in it now are:
Idle jets 62.5
Accel pump 90
Main Air 240
Main fuel 190
I dont know what pump nozzles are in there or which ones should be.
I got these sizes off the computer but never had a second opinion as to what should be in there.
Any help is GREATLY appreciated
