I'll have to look up my specs from years past when I had a 36mm. I have a 38mm now. I know they're pretty similar, but I can't remember the 38mm specs either.  :(

I bought a 35mm PWK A/S a while back, it came with a 160 and a 48 pilot, and that was pretty dang close.  I think I'm running 162, and the same 48 pilot.

My logic says if the 35mm was so close, then I would estimate the 36mm would ALSO be close, and it would come with a 165main and 55 pilot.

after talking to carb parts warehouse.  it was suggested a 35mm was a better choice for my application.

I'm pretty happy with my 35mm.  I was specifically looking to boost the low/mid, and also hold the top end back a little.

The low/mid is definitely there, throttle response is good, and it really didn't choke the top end as much as I thought it would, I'm still constantly bouncing off the rev limiter in the lower gears.  Engine is stock bore, stock porting, with a basic FMF pipe.  I built it to run along side a piped 400EX, as a basic trail machine, and it still walks away from the 400.

Totally happy with my 35mm, this is a fast, peppy little trail machine.

Did you ever get that 35mm up and running?  How do you like it?  What kind of build was it?

It is on the back burner.  i had another kid and that has been taking up free time.

I intend to get back to it soon.  it is just a 250cc gasgas in the other ATVs section.  I am just about finished getting the pipe figured out so i will move onto the intake side.
