my problems

ok here i go. i have a 88 mazda. the motor has about 19,000 miles on it. its been bored over 20 over. mild cam, pace setter longtube header. webber 2 barrel carb. stage 2 racing clutch. but my questin is it runs like crap......why. i broke the breather so it has no filter but at idle somtimes it idles really high and sometimes it stalls out when i let off tha gas. sometimes it runs perfect. others it pops and backfires and all the other little noises that make u mad. 3 vacuum hoses arnt conncted. could that be it? or do i have another prolblem. and also could my idle pully be messed up? ty for any info.

Well.. u said you have a webber.. there should only be one vacume hose.. going to the dizzy.

Give me your Weber, I have a stock carb. , Just kidding.

You found your problem. As Mike said, you only need one vacuum line and that is to the vacuum advance on the dizzy.
Plug the rest of the vacuum ports in the carb. You are running too lean due to vacuum leaks. Vacuum leaks will cause your high idle.

Once you plug all the vacuum ports, then start tuning the carb especially at idle. Above idle and wide open throttle, jetting controls the fuel mixture.
Good luck and post your findings.

sweet guys. thanks. i believe its fixed. it soo neat to find people who dont just say " put an LS1 in it. lol. anypne know where i can find a breather for it?
