So I been trying to make a decision for a carb for my R what is better 38,39pwk air striker or 38 pwm

[Eddiesanders250]

the 39mm pwk carb is the best. This was already explained. The air stryker does not perform as well as the non air stryker.

Well I have been searching around and alot of websites say the pwm is the latest and greatest. If this has been explained can you point me in the direction for the link because Ive looked everywhere with the search.

I forgot where it was explained, I know zedicus explained it and beerock also did.

[beerock]

the 38 A/S pwk has more throttle response from bottom to mid

the 39 pwk has decent throttle response and mroe top end.

So they are pretty evenly matched then?
