Engine runs ruff

Post by sledman3064 »

I have a 1970 f100 1/2 ton 4wd w/ a 360. The issue I am having is that my truck runs like it is choked when I give it full throttle and acts fine when I let off I think its a carb issue but I could be wrong please help thanks

Do you have manual choke? If so check to make sure it has smooth action. I just got through working on mine. I will know when I leave for work in the morning. It does seem to be running a lot smoother at idle. Hope this helps
