Ok my 1969 chevelle is WAAAAAAAAAY fast. However, lately the acceleration is acting funny. While in third gear, (3 speed manual) it accelerates pretty quick when i really step on it, however after a few short seconds it actually starts SLOWING DOWN!!! It feels almost as though i am down-shifting, its the same type of feeling. It is really weird.. And then all of the sudden it will start accelerating again. I dont get it!! HELP ME!!!!!!!!!!!!! Thanks!

You could be running out of fuel. If you have a pressure gauge mount it somewhere outside of the car where you can see it and run it again and see if you are losing fuel pressure.

Fuel pressure or one of the internals in the carbs isn't working correctly. Be more specific about your rpm range and maybe one of the pros on the site can point their finger at the source of your woes.

What type of carb is it?

Mark

When you say it feels almost as though you were down shifting are the RPM's still rising as the car slows. If they are then your clutch is slipping

Sounds like fuel pressure to me. May cost a bit, but its better then leaning out your engine and blowing it up!!. CHRIS

Is your fuel filter clogged? Sometimes even the simpliest of things can be overlooked.

You just felt like you were going slower because I was accelerating past you so fast that day.

NOT ENOUGH gAS, GasMAn.... or a clogged fuel filter, or a slutty clutch.

sorry, dumb question. do you have enough fuel in the tank? fuel would run toward the back on acceleration then when the nose drops, catch up again. we all tend to over-think these things. good luck.

Slipping clutch? Possible, recheck adjustment. Low on fuel,also possible, have you adjusted the floats in your carb? Let us know what you find.

thanks for all your responses... Unfortunately i havent had a chance to drive the car since i posted the original message, as its getting some body work done... Hopefully i will have the car back tomorrow and I will be able to check everything you mentioned.. Thanks!!!!
