Question Carb Help Needed

I have the OEM Motorcraft(2150???) 2 bbl carb on my 304. Normally it starts at the touch of the key(no cranking). Just before I headed down to Moab this past weekend it started acting like it is flooding after I shut off the engine. When I try to start it after a few minutes it is flooded and I must push pedal to the floor to fire it, when it does fire heavy black smoke comes out(if engine is warm). If the engine is cold a whitish-gray smoke comes out(unburned fuel???). No adjustments had been made prior to this happening, except a new fuel line was installed a few weeks ago. It runs fine at highway speeds even up to 80 mph! Gas mileage is higher than ever before, and it performs flawlessly on STEEP climbs. The only problem is the rich smell and my burning eyes from the fumes when rockcrawling. It appears to be worse on the drivers side of the engine than on the passenger side(tail pipe very black and more smoke on driver's side). Could this just be a mixture adjustment or is it time for a rebuild???

Thanks for your advice

You may have to adjust it, you could e getting more fuel pressure due to the new line, if the old one was leaking. Could also have a stuck float, so it's not responding to the changes in angle, etc. while off-roading. Check those 2 things first, then do a rebuild if you have to. 2-BBLs are pretty simple to rebuild. <img border="0" title="" alt="[Wink]" src="wink.gif" />
