I was going to wait until tomorrow so not to bother the neighbors, but the more I thought on it I couldn't wait. They should be used to chainsaw noise by now anyways. Lol
Kudos to you Stump shot, we salute you for starting the saw....at night...gauge hooked up... multiple piss-revs...no consideration for the neighbours....and stuff.

@tree monkey Is there any plan in your future testing to alter the ratio between the fresh air charge and the fuel/air charge by increasing flow to one tract or the other?

i'm trying to get the most air I can through the engine, the only way I could off set them from there would be to restrict flow in on or the other, that would be going back words in my mind

Nice test Steve.

It would be interesting to see what modding the Motor (oops engine) would do to those signals. Would raising the transfers up or intake floor down shift those points?

Saws don’t need impulse to run at WOT, the Venturi will pull fuel out of the wet side and the open needle out of the fuel line through the pump side. They need impulse to fill the wet side for starting.

If anyone wants to question this, look at the build threads for the China 440’s this year. Impulse line geometry was wrong. Nearly no impulse, saw ran just fine but wouldn’t start or restart for shít.
