Roch Quad rebuild difficulty?

In the 8 years I have owned my car I have learned so much about cars in general. The one thing I have always been terrified of is the Rochester because of how many shops and people have said how tricky they are. I'm tired of trying to find a shop that can rebuild or tune it properly and forking over all the money to have it done. So I think it's time I give it a go.

I'm no mechanic and the closest thing to a automotive carb I have rebuilt was a craftsman lawnmower. So I have the Haynes manual as my trusty sidekick and I want to tackle this project on my next couple days off. A full disassembly, deep clean, rebuilt with a kit and then hopefully tuned to what I want.

So my big question is, how difficult will this be?

I'm no mechanic and the first carb I've rebuilt is an E4ME Qjet

It was fairly straightforward. If the carb is in good condition it shouldn't take very long. Get some schematics and manuals first and read them so you know what you're dealing with.

I've got some down time at work and will be reading through my Ruggles rebuild book, if you have never rebuilt one before and handled it well then I think I should be able to take it on.

while there, double check the primary bushings for wear. with the carb off, hold the throttle open and check for play back and front on the primary shaft. any slight wobble requires a re-bush. which isn't that hard but you may need to find a drill press.
