Just got back from a test drive with a small amount of advance and it ran better. I'll go a little more and try again but have to leave for now. I think this is the right track. Thanks to everybody!!! Had no idea you could go past the BB.

Thanks

Mine is the one on the right with the small knob. I think that is for change in altitude - isn't it?

Elevation around 850ft above sea level. Valves adjusted recently and didn't make a difference. Sill need to pull the plugs but I put new ones in awhile ago and haven't driven it much. The gas is a little old but this problem has been there since...

I'll be using a timing light as well. As the timing changes does it change the vac as well or is that just rpm? Mine is low - around 17 and should be around 20. I'm going to go at this slowly like you said and go for short trips.

I was planning on having a vac gauge hooked up while changing the timing. That should work OK don't you think?

If I advance the timing until I get 20+ vacuum do you think that could help with the hesitation problem I'm having? I never thought of going past the BB until the responses I received.

I think mine is an advance type but now I'm not sure. It does work because with the vac line hooked up and holding a timing light as I accelerate the motor the BB moves. The vac line from my dist. goes to the bottom of the carb facing the motor...

Advance. I didn't know they even made a retard one.

I have to pull my plugs and double check the points. Hopefully I'll have time this weekend. Thanks again

OK, I'll give it a shot.

Should I advance until I get 20+ vac? With vac line to distributor blocked - correct?

I'm about 850ft above sea level. The BB is 7btdc. How do I advance to 10 or more accurately?

Vac at idle is 17. I think it's a little low. Sprayed carb cleaner all around and no rpm change. Stock distributor with new points, condenser and cap. Wires are almost new. I've played with timing a little but doesn't help. I think it's the carb...

Thanks, I think mine is a 2150 but looks very similar. I'll check it out.

Wow thanks! I haven't looked at the plugs lately but points are OK. I'll check both and get a bottle of Techron.

OEM non USA like Brian said? They are pricey from what I've seen. Do you think the hesitation problem I'm having is fixable with the Motorcraft?

Where is the best place to get a non USA carb?

Hi guys, it runs pretty good but hesitates on acceleration. No vacuum leaks, compression is good, timing light is steady on the BB. The carb came on it when I bought it and had it professionally rebuilt but something is off. I've been playing...
