Topic: 22R carb help/vacuum lines

[jkimmel]

--------------------------------------------------------------------------------

I am looking at the vacuum advance on the distributor, and so far I've got no lines on at all right now, re-installing everything and eliminating all emissions equipment. I've been searching around, looking at manuals, and yet I cannot figure out where the two lines come from, or if it even matters. There is a copper boss that plugs into the side of the manifold, and one of the lines looks to be from there, where is the other?

Can I just put a brass plug into that boss and run a pair of vacuum lines from the carb to the distributor, and does it really matter which lines I use? There are like 10 of them.

Anyone know? I'm really getting tired of this junk

Anyone know if there are lines other than the distibutor that I must have? I have no high altitude compensator, I *think* the rest is emissions

on my 83 they connect to two hard lines a few inches from the dist.  I just replaced all my vacume lines so its still fresh in my mind, I will get out and do a visual later and report back. If you can look around on the internet I remember finding a complete diagram for it somewhere.

yep thats it the top one connects to the upper hard line and the lower one hooks to the shorter hard line. The hardlines end up at the carb and yes I think it wont really matter where you get the vacume from may be some trial and error to get it right.  Someone with more knowledge on removing the stuff will chime in soon.  Hope it helped.

thanks man, the hard lines are on the floor halfway into and injection conversion and lo and behold I have an old style head.

could you trace the hard lines and tell me what they connect to on the carb and or manifold?? That would be a HUGE help!

[8D3TOY]

sure give me til tomorrow and I'll pull the aircleaner and trace em out for ya.  What year are you working on?

its an 85, I think the motor is 83ish, or at least the head is, not EFI compatible

I wish my didgi cam worked! the two hard lines wrap around the head twords the carb, then the lower one T's off to the vacume switch on the fender they then continue to the carb and attatch to the only two vac ports below the fuel inlet.  The hard line that T's hooks to the upper port on the carb, the other goes lower.       http://www.autozone.com/servlet/UiBroker?ForwardPage=/az/cds/en_us/0900823d/80/18/90/70/0900823d80189070.jsp                                           Hope this helps you, my link kinda got jacked up hope it works, good luck.

yea,  get the EFI  intake from a 82-84  Celica  bolts right up to the older heads

I think I've decided that I am going to get a reman longblock this winter and swap out to a newer fresh engine, then I can add the EFI to it, I've got the entire conversion package.

Finally got my truck running today, its almost done. It runs ok right now, but falls on its face when you hit the gas, works fine if you roll into it. Timing is way off from what the books say which is "0." Get it too close to there and it dies. I guess I'm not too sure where to go from here, what sort of vacuum does the carb need to see at idle, would it be better to get it from the manifold?

What else, is there a method to tuning the mixture?

Also the floats are way high, the level is almost to the top of the sightbowl, would that cause idle/richness other problems?

Anything will help!!


Oh and its an 85 pickup with a 22R and a stock carb!
