everhthing has been rebuild to oem spec. new fuel pump and fuel lines also. That darn thing wont idle and wont start unless the throttle is partially pressed. If the rpms are above idle it runs great just wont idle.

You try turning the idle screw in so it raises the slide a little, this is how you control the idle, you set the idle once the Engine is warmed up. if you make adjustments to the air screw adjusting the fuel mixture for idle to 1/4 throttle you might have to come back and adjust the idle again.

I can screw the air screw all the way in and it does not make a difference at all? Possible air leak? also i am running a metering "T" instead of a 3 way valve.

What about the idle screw is it turned all the way in too?

With the air screw all the way in your trying to flood it with too much fuel and not enough air.

sorry i meant the idle screw! thanks for you help

If cracking the throttle just slightly will keep it running try to turn the air screw out when it get to 2-1/2 turns out from full in your probably wasting your time, you might be way to rich and it just needs more air with the fuel your giving it.

If this don't help try removing the restrictor in your Tee thing maybe its trying to force too much gas in the carb and the float cant react fast enough?

How are the Engine mounts does the Engine shake really bad? I have seen broken Engine mounts allow the Engine to shake so much it upsets the float in the carb makes them run all funky.

Well i got the beast running and it will idle! I took out the metering T and put in the stock check valve. It will idle good now but i have to squirt oil/gas mixture into the carb in order to get it to start when cold.

My air screw is set at 1.5 turns out. Maybe adjust that out more?
