Carb has too much idle hole drilled?

Victory!

Got it! It was the intake. I pulled it and got some good felpro gaskets and RTV'ed like crazy and torqued the intake down to specs.....then I saw that the stupid cork end gaskets had been ejected so I RTV'ed the ends shut and WHAM! It started up! What a difference.

I was using 5-6 full turns of all four idle screws to try and get it to idle.... now, I am using 1.5 turns of each of the 2 fronts only and it idles like a charm! It can actually idle lean! The avenger never was able to idle less than med rich. That black smoke mentioned before was actually burning oil from the cylinders I fogged. I know cause there's a pool of grey burnt oil behind the car.

I ran it for 30 mins to clear out the cylinders and the exhaust and apart from a header that refuses to accept it's pipe, I'm done.

Only one quick question left.... The idle screw. When I had it backed out, it was coughing along at 400 rpms or so and I had to put the screw in to slightly and sudenly hear a hissing sound and it then started to idle regularly. I thought there was supposed to be a small amount of air coming in even with the blades 100% closed....oh well

IT RUNS!!! WOOPEE!

Thanks to everyone for helping out!

Ok Heres the Thing...Dont Ever use RTV on any Head Surface...Including The Intake Port Runners.....The gaskets you buy should have a coating on em for when they are torqued down and warm up they seal great.....The end Gaskets I get are made of rubber and have lil saddle like tabs that hold them in place
