Hi all!

I have been working on a new project and its a '46 CJ-2A. Everything has been working well until I tried going up hill. I have tried maxing out the throttle while stationary and this doesn't happen. When I go uphill (or maybe apply enough torque) the engine starts to backfire and lose power. Oddly enough, the choke likes to engage more and more when this is happened. I am diagnosing the problem, but would anyone think it would be a timing or exhaust problem? I am currently checking points today.

Thanks and any help is much appreciated
