The engine hesitates or bogs when I try to acelerate

Possibly: dirty fuel filter, dirty air cleaner, incorrect fuel mixture screw setting, carb needs rebuild, if it never ran with that carb could need re jetting, weak coil, bad motor ground? Just a few things I would check out.

Sounds like the advance mechanism in the distributor is not working.

There are a couple of reasons that could happen. The advance springs could be stretched out or they could be disconnected.

You need to put a timing light on the car, read it at idle, then bring the rpms slowly up to 5000 and read the advance at every 1,000 rpms.

If you have a stock distributor, you should have full advance at 5,000 rpm which should be around 36 degrees.

The advance readings in between idle, which should be 14-16 degrees, should advance approximately progressively.

Sounds complicated but it is not. It will tell you if the mechanical advance is working or not.

When you do this you should disconnect the vacuum advance hose to the engine and plug it temporarily.

Remove the air cleaner & make SURE your choke isn't sticking.

Or simply disconnect it & wire it OPEN!!! for the "Driving Test".

Do you have site bowls in your carburettor?

If so are your fuel bowls FULL, indicating sufficient fuel flow.

You can always plug your fuel line & with a small gas can & fuel hose, connect the fuel hose to the carb to bypass the entire fuel delivery system.

does the engine run better with the bypassed fuel system?...

Start with the basics!

You have Spark!...are you getting enough "Air"? & enough "Fuel"?...Mark

I took it to a guy who build dirt track engines. Used him because i did t want a comunity college mechanic working on it. The itital timing is at 14 and over all at 36. He suggested that we change the advance springs in my dizzy to one blue and one green.(msd ready to run). My carb is a new holley 750 and a edlebrock high rise i take.(got both from precisiom preformance). When he set the timming the vacum advance was not removed from the dizzy. It idles fine and runs smooth it only starts stumbling and fumbling when im moving. All new dizzy carb manifold coil plugs wires (fuel line and filter kit from (PP) also

Oh and not to me tion but that ball of fire that came out of the carb burned up a brand new air filter also

I have a Carter AFB which is the same as the edelbrock. I had to buy a jet kit and play with the jets, metering rods, and accelrator pump settings before I was happy with it. Just because a carb is new does not mean it is going to work well until it is tuned for your specific motor.

I have come to realize that from more reading. Out of curiosity what jet size are you running?

If you are asking about my jets I dont remember what size they are. I think my carb is 600 or 625cfm with vacuum secondaries and my motor is stock with the exception of the performer manifold and Edelbrock carb. I put that set up on my car back in 1985.

first step is to disconnect & plug the vacuum advance hose, otherwise you may have some vacuum advance influencing the base timing

maybe let the community college mechanic take a swing at it?

How did you hear about that? It wasn't my fault. He was brewing something made from desert cactus and gave me a sip. I don't remember anything after that?

HEY Doug; When I initially read the caption "Retard Problem"...I thought somebody was complaining about a certain member of Pantera International

Sorry to read you were slipped an organic version of a "Roofie"

Did the witch doctor at least buy you breakfast in the morning?! ...Mark

Well first off, retard is a politically incorrect term these days. I thought personally you would object to the usage?

I simply don't remember what happened with the witch doctor over night but I did wake up covered in body paint, hot wax and with a chicken cuddling me.
I am concerned that maybe I got married to it overnight?
I can't ask the WD since he was deported as an illegal alien and has no electricity in his country.

Never go full retard.

Tropic Thunder fans will get it. Others, back to your regularly scheduled thread.
