Hey guys, 
 
Sorry it has taken me so long to get back with you.  I'm a student right now and haven't had much free time to work on my car.  My original email is below to remind you of the problem I am having.  
I have taken the advice that I've gotten.  So far we have checked the accelerator pump, power enrichment circuit, and the carburetor's have been synchronized.  We are going to check the timing this weekend.  We didn't start there since the engine had just been rebuilt and everything put back together (by someone else) and we figured they had done all that already.  Anyway, after checking all this and with the carburetors being better synchronized, it idles smoother but the "bogging down" problem still occurs when you press on the accelorator.  Any ideas as to where to go from here?  Thanks for your help.

Stacy, most important of all is to look for a local club. The resources available through the membership is probably greater than anything you can buy in a Corvair book. Next recommendation would be to join CORSA, the national club, if you haven't done so already.

Seth is on the money with his diagnostic procedure, let us know what you find.

Hello.  I am hoping one of you may have some wisdom you can pass  along.
I'm new to this Corvair thing and new to cars for that  matter but I'm learning
quickly.  I recently acquired a 1965 evening  orchid monza coupe and I just
love it.  As of lately I seem to be having  some carburetor problems.  (That's
my guess anyway).  The car idles  decently but when I press on the gas it sort
of "bogs down" like the engine is  being flooded.  I'm assuming this is the
problem but am not really sure  how to go about figuring out which carburetor it
is or where to go from  here.  I would greatly appreciate any advice.
Thanks!

Stacy - Before you dive into the carbs, be sure your ignition timing is
correct. If you have a timing light - (if you don't, find someone who does) -and
check the timing at idle. Depending on the exact motor in the Monza, the
timing  should be at about 12-16 degrees BTDC. If it seems stable there, reach down
-  CAREFULLY - and remove the hose to the vacuum advance port on the
distributor.  Plug the end of the hose with something like a golf tee. Now check to
see if the timing has changed. If it stays the same with the hose on or off -
at  idle, then you can hook the hose back up and start with the carbs. If the
timing  at idle changes with the hose removed, you will need to do carb
adjustment,  especially of the idle position screws. There should be no vacuum
advance at  idle. Leave the timing light in place - Cylinder #1 or #2. Turn the
motor  off. The first easy check is to see if each accelerator pump is working on
both  primary carbs. After removing the air cleaner, look down the throat of
the carb  and see if a little stream of fuel appears just above the cluster in
the throat  of the carb, when the throttle is quickly opened. A little shot of
gas  should come out when you crank the throttle open. If the engine will
run okay, you can check this with the motor running, and the  transmission "OUT
OF GEAR". Aim the timing light down the throat of the  carb as you crank the
throttle open. The flash from the timing light will  "freeze" the fuel as it
comes out of the discharge hole on the carb. If this  still shows nothing, then
it is, indeed, time to go into the carbs. - Seth  Emerson
