What kind of Petronix? If you are still running a 009 you are not going to get
rid of the flat spot. That is caused by the advance curve of the 009 in
conjunction with the 34 carb. There are two ways to get rid of that: Well,
actually 3 ways if you want to count going back to the stock distributor. One:
and probably the best (and also most expensive) is to go to an SVDA
distributor. Two: you can change the advance on the 009. A stock 009
advances about 22-24 degrees. It does not advance fast enough for the 34 carb.
So, you can decrease the advance on the 009 by going into the distributor,
bending a tab down to prevent advance to about 12-15 degrees then set you
static advance at 15-16 degrees so that total advance is still the 30-31 that
you want at 3,000 rpms. Basically this means you have about 15 degrees of
initial advance which prevents the stall when starting off. Essentially the
problem with the 009 in conjunction with the 34 is that
the 009 does not give you enough initial advance quick enough for the carb.
Now, none of this has anything to do with the problems you are now
experiencing. Make sure you have the carb tuned correctly and are getting
fuel. Make sure you have good hot spark. Set timing static at 7-8 degrees
BTDC and then check total advance with a timing light. Should be around 30 and
not more than 32. Also make sure your points are set at .016 if you go back to
points.

My 2 cents. If it wouldn’t run smooth with a clean set of points and
condenser it will never run clean with Petronix. Go back and try it with new
points and condenser and then look at your coil, how hot is it?
. Seen all those symptoms with those problems.

Was running a 009 but had horrible flat spots in acceleration.
Read some threads recommending a svda replacement. Purchased a petronix
distributor. Now we cannot even get an idle. Timing has been tried at
varying degrees of advance from tdc all the way to about 18
degrees.
Ideas or suggestions?
