*Subject:* [FlyRotary] Re: idle adjustment

I did think of one additional possible solution. Each of the barrels on the TWM has a small air inlet with a pin. I have these closed all the way because I thought it might help with the idle. However, I now wonder if maybe that air inlet is for the purpose of atomizing the fuel.... Does anyone know? Maybe I will try to open them up a little.

Dave;

As I understand it, these just provide adjustable air bypass for the throttle plate, and is primarily for more precise idle adjustment, and transition coming off low speed idle; so may not be very relevant in our application. It is probably good to have them open a bit. I have mine set at 2 turns from fully closed.

I haven’t asked to folks at TWM, so if you really want to know, give ‘em a call.

That's pretty much it. They're usually used to balance the MAP at idle on 4 cylinder Brit engines - MG, etc. All they are is an adjustable air leak.
