[NoVa-Corvairs] July meeting

[Frank DuVal]

The choke doesn't open all the way by itself? Wait, the choke plate 
should be OPEN at idle, not closed. Closed choke  is only on a cold 
non-running engine. As soon as the engine starts, the choke pull off 
will open the choke plate to about 1/4" (actual spec is in the shop 
manual). When warm, the choke plate should be standing tall, fully open.

Are you meaning throttle plates?  If so, new throttle shafts are 
available from our vendors. Pretty easy to install. Just have to deal 
with those brass screws.

A wiggling choke shaft is not too unusual. But, these are also available 
new. Cheap too.

Gas dribbling means it is time for a rebuild. Could be just a too high 
float setting or leaking needle/seat, but it never seems to be that easy.

With Bob Helt's book, you can tell the year of the carb. There are minor 
differences between years.

What year is your car?
