Hi Guys
I am home now and decided to visit my family in Virginia I haven't seen in 15 years, my 16 year old nephew bought a 1983 F150 with a 302 in it, he is trying to learn how to work on stuff and my twin brother is basically clueless,(he is a computer guy). here are the issues.
1. the truck has not seen the road in many many years.
2. my nephew installed a NEW motorcraft carb and hooked all vacuum lines up. did not change EGR spacer plate gasket.
3. would only start with starting fluid and then would barely stay running, had to feather gas pedal pad and would still barely run
4. once put in reverse or drive would stall immediately.
What I have done the
1. disconnect all vacuum lines except vacuum advance, pcv valve, vacuum line to tranny, and EGR plate to carb at the front.
2. new cap, rotor, plugs., old ones lite me up bad when I touched them.
3. adjusted both fuel/air screws and main idle screw.
4. removed the "extra plastic spacer" that was installed that is for a aluminum intake, lots of cracks on it. this has a cast intake so only the EGR plate is required
5. new gasket from intake to EGR spacer plate, and EGR spacer plate to carb.
6. EGR valve is plated off on the spacer plate.
results
1. engine starts easy.
2. after warming up for a couple of minutes it will now idle on its own but has a slight surge to it.
3. will go in gear and stay running on its own although it will surge while in reverse and going forward and the engine will bog down when I try to drive it so I have to feather the gas to keep it going.
4. when I spay starting fluid onto the EGR spacer plate behind the carb the RPM rev's up, ( i am suspecting a cracked EGR spacer plate to carb).
5. it seems like I still have a vacuum leak that is effecting the carb idle and tranny
What i would like to do is remove the Vacuum carb and go with a generic 2 or 4 barrel carb. It seems like this one is very sensitive to vacuum leaks. what would be needed to completely remove this carb or keep it and go with a pre smog era system? and will the tranny still work if it has the vacuum lockup convertor?
I am leaving Virginia Saturday and would like to give my nephew some suggestions. It is a nice beater truck and I hope to get it going for him so he can drive it once he gets his license.
thanks for any help.
