30 degrees initial timing with a total of 60? Are you sure you are timing it
off of the #1 cylinder? That would be the front plug on the drivers side. 30
degrees initial would certainly make it very difficult to start if at all. I
would expect lots of backfiring through the carb. - Gary
Yes, I am checking the timing from the # 1. I am convinced the problem is
with the ignition since it is most certainly getting air (same problem with
air cleaner off, throttle opening just fine) and I can see the discharge
nozzles shoot fuel when I hit the throttle (so it is obviously getting fuel
to the float bowls). I also have not made any adjustments to the carb
recently. I have also had it stop running after it was fully warmed. As for
the timing, the damper must be incorrect or something else is way off. I
checked the timing several months ago and just left it where it was at.
Bringing it even to 20 degrees at idle caused a noticible reduction in idle
quality. I may try a new cap and rotor, but like the others it will probaly
only last a month. Any ideas why my cap's terminals get corroded so quickly?
It doesn't burn oil and there are no other signs of internal engine
malfunction. I put roller rockers on about 3 months ago and it ran great so
I doubt it has anything to do with valve timing. Maybe I'll just cut a hole
in the hood and drop 22k on a new ram jet ZL1. That should solve the
If it has an electric choke, make sure the connection is good and is getting
power. If it is spring operated, check the linkage for binding or see if
something has come loose from the heat riser spring.
With the engine cold and not started, activate the throttle and see what the
choke flap does. It should close, but not all the way. Then start it (if you
can) and watch what it does as it warms up. It should open part way and then
when you give it some throttle it should open up all the way when the engine
has warmed up.
Good Luck! Fun ain't it ;)

What kind of car is this? Did it originally come with a carb, or was
it fuel injected (even TBI)? Black smoke is almost always a sign of a
rich air fuel mixture.
Make sure the smoke from the tail pipe is black and not blue. A blue
smoke could be a sign of something a little more serious.
