There was a post awhile back with a link to a pretty good qjet overhaul procedure and I would appreciate it if someone would repost the link. Thanks in advance.

 

Cmon, I know I saw a link here in the past, help a guy out.

 

Not sure if this is what you are looking for but some info anyway.

hmm, my webspace, indeed.

The first 3 links, are .doc files, that may be handy. They're primarily for non-cc q-jets though. I don't know much of the specifics related to cc-jets, so I can't help ya there.

 

LeoP,

The link below will show you a photo of the tools you will need and a Haynes Rochester Book that [IMPO] every Q-Jet Owner Should Have.

Tools Required & Haynes Book

The directions that come with a rebuild kit are normally pretty good for assembly and disassembly of the Carb. However, they do not address how to actually tune and check the carb. It will onlu take a little reading, a little time, and a few specialty tools to get it right.

Why do you need to rebuild the carb?

Sincerely,
Kurt

 

It is on my sons 85Z and it looks like its never been apart and the car runs very rich, haven't even hooked up a scan tool to it yet. Thanks for your help.

 

A weak O2 sensor can cause rich running for a very long time before it sets a trouble code. Are you getting any trouble codes (SES light)?

 

My vote is bad TPS. ECM thinks the engine's running WOT all the time: won't throw codes. Let us know, though, I'm seldom right.

 

I will repost whenever I have a chance to scan the comp, it'll be at least a week as the car is not here with me. Thanks for the help.

This help at all?

I finally got a chance to scan the computer last weekend, the O2 sensor stays at .45 volts and the engine temp never got above 135 degrees in an hour of running. I am going to replace the engine anyway, so it'll be awhile before I report again since it is a weekend effort.

Thanks for trying to help me figure it out.

 

Don't replace the engine just cause the carb's giving you problems!

What are you going with and what induction system?

 

Better take a closer look at the tires, too. If they're worn, you might as well replace the whole car. Before you scrap the old one though, drop me a message...

Seriously, if it were mine, I'd solve the problem BEFORE the engine swap, or at least fully identify the problem. There can be more than enough variables when exchanging engines, and complicating it unnecessarily with existing problems might not make your startup any easier. If you start getting more unusual problems with the fresh engine, you may really be in a quandry.

 

The engine swap is a given, the engine smokes blue to beat the band and has blowby like no tomorrow.

Thanks for your take on the problem. I'll try to remember to post the results when the swap is done, don't expect anything too soon as it is a weekend project.
