changed distributer now runs rough

[zombie437]

I just switched distributers in my 86 5.0 HO it was running the one that came with fuel injection, now I am running carb distributer. My question is it runs but no matter how much advance is seems slugisg, could it be off a tooth and still run? Thanks

What fuel injection do you have? some fuel injection setups need a dizzy that is compatible with EFi as the advance is computer controlled.
if you can turn the dizzy to get any advance you want they your not really a tooth off. If you couldnt tunr the dizzy enough then you might be a tooth off..
might want to recheck your plug wire routing as well make sure you dont have any mixed up.

wires

When i first put it in, it was 180 off, switched it then had the wrong firing order for HO motor. The motor was FI and then I went with carb,never ran very good then heard I needed early distributer out manual trans. Ill check wiring again thought they looked good but ive been known to miss some stuff thanks.

My cap was loose the other day (I must have knocked it) and even though both clamps were still engaged it was cocked and ran funny.

what year of distributer are you running now? what vehicle was it out of? What do you mean by carb distributor? Usually most carberated engines had flat tappet cams if your engine was a EFI engine then it should have a roller cam so your carb dizzy probably has the wrong gear on it as the roller cam will eat it up.

Make sure you have the right dizzy and gear on the dizzy for a carb roller 5.0, I think only one year, 1984?
