    Check that your catalytic converter isn't plugged.

    Re: 84 accord acceleration problem help!!!!

    I had face similar problem 2 times on my Honda Accord 1.6 carb.

    First time was the fuel pump. If itís getting old the fuel pump? It starts overheat - stuck some times and it doesnít provide enough fuel.
    If itís the fuel pump you can understand it easily. When you face this problem switch off the engine for 1 minute (to cool down the fuel pump), and then back switch on the engine. If then car is accelerating normally surpassing 3000-4000rpm easily, then for sure is a worn fuel pump which needs replacement.

    Second time I face the same problem (this time the case was constant, nothing changed if I switch off the engine for 1 minute), after checking every think with my mechanic, electric system, changed again the fuel pump Ėfuel filter and problem remains, I found that the problem was the carburetor.
    It needs a totally rebuild (not just cleaning) because all the carburetorís elastic parts needs replacement. Especially worn out carburetorís elastic O-rings cause vacuum leak, that make the car running reach and having lethargic acceleration not able to pass 3000rpm.

    So I believe the solution on your problem may be 1 of the 2 above.
