Well im having some trouble tuning the engine. It a stock port 13b with functional 5/6 port. Running the stock se fuel pump n regulating it with a Mallory 4309. Running RB full exhaust system.(not the street-port one) and msd 6a box with msd blaster's (x2).

Seems my idle is too lean. (glowing headers bs). When i floor it, feels fine n pulls hard. But lil boggs here n there. In cold start, my wide-band reads high 12's low 13's. but warmed up it goes in the high 13's low 14's.

Right now the idle screw is about 3 1/2 screw out.

Heres the jets that rotary shack supplied:

Main-180
E-tube-F7
Air Correction-160
Idle Jet-65 F8
Accel. pump jet-45

Hope to read some good info. and yes ive search. If you have any good links pls post them here.

 

sounds close, you need a 65f9 and you should be fine. your afr's at full throttle are good. contact rob and he will take care of you. do you have his e mail address?

 

Yea MaX Power contact Robert when you get a chance.

 

ya ive been calling him. all calls go to his voice mail. seems hes too busy for me.. tear..

hay kerebrus, u still doing the carb turbo set up?

Im peacing my **** together. hardest thing on my mind is making the hole for the oil drain on the front cover.

Aslo how many turn outs on ur idle mix screw? u ahve a 48 dcoe right?

 

how much of a different would the 65f9 make?

 

well since your out 3-1/2 turns and its still bogging you need a slightly richer jet, the 65f9.
i was at rob's shop yesterday, and he has got a full house and some. he will get to you, dont worry

 

Yea Rob has been really busy lately lots of cars lots of work. Email him and he will respond for sure, or try calling again sometime. Yea I have a 48DCOE in turns of the idle screw I'm not sure exactly but its probably somewhat similar to yours. My setup runs more rich then Bill Gates a little bogging here and there but nothing that bugs me really. Just got my turbo plenum carb hat done and put in a new RB clutch setup and light steel flywheel. I'm getting ready to upgrade the fuel pump and and get an FPR to go along with it, after that I'll be about ready for turbo.

 

I appreciate all hte help guys. another question, what should my timing be? for leading and trailing?

 

well i got a call from robert (great guy) is sending me a f9 idel jet. hope to get it soon and on the car asap.

Anyone with the timing advice?

 

Hahah well i got the jet's 2 days ago n got more then i wanted. (poster of the evil angel poster)

Got the jets in, adjust and advance the timing a bit. First night, headers had lil glow to them, and today none at all. im just finding the right mixture for the idle screw. rough idle n vibration. cant get a steady idle.

When i drive it, hte rpm would stay at 2k even if i would lower the idle speed screw.
whould this be cuz of the accelerator pump screw?

Well i got some pix of the car up to date. let me noe what u think.















And a diy pan hard lol

 

put a return spring on the carb. where is a pic of the poster? fail!! nice ride tho....

 

I em running a return spring. can anyone explain to me how the accelerator pump work?

Ill try n post a vide of my car running 2 marow..

o ya here u go...

 

god dam!!!! so how did u get this? poster that is???? and where?

 

I have no idea. I asked robert for some f9 idel jet n this came with it hahaha. give him a call, hell prob hook u up with the real thing hahah.
