Super Jet 2009 SJ tuning issues

[snuffysmith]

I have a 09 SJ, stock motor and head (160 psi), AM flame arrestors, and FP limited pipe.
I'm having trouble dialing the carbs in. Here's the current setup
Main 135 MAG, 137.5 PTO
pilot 70
N&s stock
Popoff stock
I'll have to check on my high/low Thursday.

It runs fine for about 10 minutes then doesn't run right at all until I let it sit for a while. At WOT it will only last about a minute or so.
I was thinking o moving up to 140 mains to try that out and if that doesn't work go back to the stock 130's.

Any ideas?
