Carb Issue
Car: 1985 RX7 GS (Nikki Carb)
The car isn't running perfectly. After not being driven much at the dealership I bought it from the Accelerator pump was leaking gas and it would bog when getting on the gas to take off or accelerate semi-rapidly when cruising. I used the various tutorials to take the carb off and change the Accelerator pump hoping that would solve my issues.
It isn't leaking gas anymore (thank God) but there is still a hesitation when I blip the throttle too quickly or go from zero throttle to about quarter throttle all at once. It doesn't seem like this would be normal even though I realize carbureted cars don't always operate as perfectly as FI cars. If I drive the car nice and smooth and take care not to jump on the throttle too quickly it runs pretty darn good. Revs right out to redline and above easily. Just wondering if the hesitation symptom is kind of normal or if I am definitely experiencing an issue.
Gas: 91 Octane BP with roughly 1/2 oz per gallon of premix TCW3 2 stroke oil from Walmart
What I have done to try fixing it:
1: New spark plugs
2. New plug wires
3. New Distributor Cap and Rotor.
4. Accelerator pump replacement.
5. Various different fuel mixture/idle settings
Just as a side note I don't remember the car really having any sort of hesitation before I started premixing it, but I was driving it very gingerly so I may never have noticed it during the first tank I drove through. It doesn't seem likely that a fairly conservative premix should be causing an issue like this but I have definitely been dead wrong before.
Hope someone can help
