can anyone help me out i have a 94 mustang that i traded for the motor is a 306 it was still fuel injected when i got the car but i recently changed it over to carb and dont seem to be able to get it tuned to run properly. I have adjusted on the carb a little but not much due to lack on knowing what it needs. the carb is a 650 demon. My problem is that when the car sets for a while it starts up good but the longer the car runs the harder it is to start like its out of time. I have messed with the timming and seem to get it good while but then i turn the car off and its slow starting again. it doesent over heat, and also it falls on its face comming out of the hole. I thing I may have a couple different problems but not sure what the deal is.
