1970 DUSTER 440 4spd 8 3/4 posi

When i move the throtle it squirts out the front like you say. I took off the valve covers and re-adjusted the rockers. I am glad I did cause the rockers needed adjusting now that the engine had oil pressure. I also found out that the rocker shaft wasn't bolted down tight. I have now torqued it down to 25 foot pounds. I guess thats what happens when you take over a project that someone else didn't finish.

after i adjusted the rockers, I started the engine again and it was still doing the same problem. But I have found out what the issue is. i have all the ports on the carb pluged except for one, and I have it with a hose conecting it to the distributer, and it back fires when I have it like that. If I disconect it from the distributer it runs fine with no backfiring, I can hold it a 2500RPM nice and smooth, I can't do that if the distributer is conected to the Carb. and I can feal the end of the hose that is conected to the carb and it is sucking more and more as the throtle gets used. I pluged the distributer, and it seams to run fine with NO problems now

Is that the vacume advance? if not, what is it?
and do I need to use it?
can I just plug it? seams to work ok that way.
