Monojet carb issues
My truck starts fine when cold, has a slight miss at idle, but otherwise runs good. The problem is when I shut it off and leave it sit for about 10 minutes I can smell gas. I opened the hood and found gas leaking out of the front of the carb. Above the idle mixture screw there is a linkage and it appears gas is running out of bowl there. I checked the float level and it is at spec. I took the needle and seat out and cleaned it, it doesn't look worn or damaged.
Also, the float is good, no holes and there is no gas in it. What else would cause this? I think the slight miss at idle is a plug wire or maybe the distributor cap needs replaced, been a while since a tune up. Any ideas would be appreciated. Thanks, Mark
