Need Help Again

[jachuck49]

This is on my '84...Once it gets warmed up,it wants to bogg/stall out. When I come to a stop and crack the throttle..it'll act like it's out of gas. It always starts back up though.It never does this until I've gone about 20/30 miles.If I keep it reved up,say 1200 plus RPM it won't stall. It almost acts like you've got the choke on???? It just started doing this all of a sudden.I've run about a half can of sea-foam thur it in hopes that would cure it....no luck.I appreciate your help.

Comon guys,I really need your help!!

My first thought is to check for vacum leaks. During idle spray carb cleaner everywhere under carbs listening for rpm change. If so pinpoint it. maybe blew off sync plug, cracked vac line, etc.

Could be a partly clogged fuel filter or maybe pump starting to go bad? If it was a gravity feed I would think tank vent is clogged.

Your symptoms perfectly describe how an engine with CV carbs will behave when the idle jets are badly plugged.

Been doing the Sea-Foam Diet? Sea-Foam is not for when you have problems but prevents problems. It will work sometimes after things get plugged up IF YOU ARE LUCKY. If you use it regulary it will prevent most fuel problems. Once you have the problem you can saturate the carbs with Sea-Foam and hope. It will still do the job a lot of times but must soak its way thru the junk that has built up over time. A little Sea-Foam every other tank or something like that and you wouldn't have the problem. It is cheaper to maintain than try to play catch up.

Question, does it back fire? If it 's like the choke is on, what color is the exhaust? before and after it starts 'acting up'.
