ORIGINAL: grabbem88

it's stock...probably is motorcraft...so there is a powervalve then...wasn't to sure on a two barrel..


the rebuild kits are like 20 bucks anyways.


thanks bernie.....i was thinking about the timing issue,and this truck fires up to easy for that...bump it and it starts..
Not saying that's the problem, but I had an 82 Capri 5.0 w/ a 2 barrel carb and that thing used to go thru them like no other. Good luck man.


Joel, nice diagram. Where are you getting this stuff from?
