As far as needing more jetting, that's up to you. I will tell you that the engine will continue to respond powerwise to larger and large mains.
I have tested them all the way up to 195 mains.
I ran out of air corrector sizes at that point. I went no further.
What you will notice as you go larger is that the engine will smoke more and more as you get larger.
I have a set of 170 mains that you can't run in the garage.
I would predict that you will settle on the 140's.
Accellerator jets also can be closed down quite a bit without effecting performance. I had them down to .40. This would reduce the amount of cylinder washing and would reduce the black cloud you get when you nail the throttle.
The problem is it makes it very difficult to start the car cold. That made it easy to foul the plugs starting up from flooding the engine by over pumping. I know that sound contradictory but it isn't if you think about it.
Also, don't look down the stacks when you are cranking the engine unless you like to look surprized. Did you ever notice how when someone has no eyebrows they look surprized?
Start the car at night if you like a light show. My kids used to charge thier friends a quarter to watch me start the car at night. It looks like you are firing up a nitro car.
