Re: Driveability Problem



There have been a lot of posts mentioning fuel quality issues. My Sport Fury 383 with original AFB carb has had the "shivers" under hard acceleration. I have added octane booster to the gas and seen marked improvement. It's a no risk experiment in my opinion. I've used both "Gumout" and "Lucas Oil" brands.

Good luck

My 65 Barracuda with a 273 engine starts and idles very well.  When accelerating it runs rough but smooths out at a constant speed. Points, timing, valves are all dead on.  It has a new, not rebuilt, distributor and spark plugs and wires are new.  The Carter BBD carburetor was recently completely rebuilt by a reputable carburetor shop but it did not correct, change or improve the situation.  The repair shop where the car now is has gone through everything and they feel that it is still a fuel problem.  In fact, they feel the engine is getting too much gas (though the fuel mixture is adjusted to spec and I have noticed no black smoke from the tailpipe).  Given all the facts above, does anyone have any suggestions?  Am I missing something? 

I have an old Stromberg WW3 that I will have the shop put on so as to compare how it runs with the Carter.  I asked the carb shop if the jets could be bad but he said no.  In any event, jets are apparently not available for this carb.  Thanks for any help. Bob from Maine
