Default Timing pofile of Stock gas engines

I took a rough measurement of my Zen 26cc, and these were the numbers I came up with:
Exhaust duration: 134 degrees
Intake port durations: 90 degrees.

Are these numbers typical for stock gassers?

I know for the much smaller nitro engines, the timing profiles are much much higher: more like
Exhaust: 160-165 degrees
Sleeve intake duration: ~110-115 degrees


Also, fo ported and modded gassers, what timing profiles are those raised to?

Well, I am not having any luck here, maybe no one mods these engines, so I will repost this thread in the Engine thread.

***MODS: Please close and delete this thread***
