I have an extremely bad flat spot in my acceleration when I am taking off. I know this is not just my car but many old Roos. I also know there is someone out there that knows how to fix this prob. Any info would be appreciated.

Replace the accererator pump check ball and plunger.

How do I go about that? I know a little about these things but I am far from a certified mechanic.

Also check and make sure your ignition coil isn't starting to die. That and your spark plugs are good and not creating a short somewhere.

Yeah - can be ignition related too, but that usually manifests itself as poor idleing and crappy running in general. But you didn't mention how it runs otherwise? Check it all out - vacuum leaks, ignition problems, etc can all cause hesitation to some extent.

 

As for the accelerator pump - you have to tear down the carb to get to it. Remove the carb from the car, and pull the top off - the check ball and plunger will come with any good rebuild kit.....

 

You probably have a Hitachi 2 barrel, but you might also have a Carter/Weber single barrel - take a look down the carb throat and tell us which you have.

I replaced my plugs and wires less than a year ago. I didn't use Platinums either, I do know better than to do that. I replaced my coil with an Accel Super Stock two days ago. I have a Hitachi carb too, I do know that.
