Don't really care about fuel economy. Just want the car to perform. It response quicker and has better throttle response.

have you check the accel pump in the carby is working???

hi datsa so how much did it affect fuel economy by using 190 in primary?

thanks

Put the bigger jet in the primary. I had the same problem. I have 190 in primary 's and 160 in the secondary's. My car bogged off the start and then picked up. Solved it by putting the bigger jets in the primarys. I run two carbs.

what colour are the plugs?
1 more vtecyo ha

yer its a new fuel pump was somthing around 2.5 or 3 psi

Have you checked your fuel pressure? Maybe pushing fuel past the needle somehow?

hahaha vtec.

yes its a stock hitachi carburetor i was just testing to see if it was the secodarys by sticky taping a 5 cent coin onto the mecanical weight to make it open up slower and it made the bogging alot less but not 100%.

thanks

yes more info needed, by the sounds of it id say the vtec is broken:]
