Quadra Leak!

<< < (2/2)

omaha:
 I agree with Cliff. The front half portion of the carb is the most important part  as far as sealing goes.
get it to seal up first. most of the warped carbs are flat in the front main body and then they take a dive towards the rear (the rear droops down). usually the top casting has conformed to this attitude. but if not always tighten up the front portion first. And I use a pattern kinda like tightening a cylinder head. start with the center screws and work towards the front screws and kinda "sneak up" on the final torquing in a couple of steps or more. I am not sure of the final spec as far as torque but I'll bet it is in inch-pounds.
tighten up the rear screws last. of course some of the older carbs didnt have many screws to hold the top to the main casting and in later years they added more so actually the later carbs seal up better in the front especially. (one more reason I like them).
 Usually the bottom of the main casting is more flat than the top.
       Okay, I got that out of my mind (whats left of it, LOL).  Good luck, enjoy!!

Toronado:
Thanks omaha, good advice.

What you say about the rear drop makes
since, and I normally followed the books
torque pattern but, your approach
to tightening the front down first is
a good idea- I'm going to try it. (the book is like from the middle out
front screw is # 5 out of 9)

Im still not sure if i should go back to the thin gasket,
it seemed to seep less than the new thick one?

Toronado:
So I tried a different tightening pattern then the book showed,
& would you believe it darn near stopped
it from seeping out and collecting on the intake.
Th gasket still gets dark from fuel (only by accel. pump) but dramatically
decreased leaking.

Thanks  every one & omaha very cool!
