I wasn't commenting on anything that you said, Taurus Flyer. At least not intentionally.

I like Cline/Iron Bay regulators and homemade systems that function like them. So, I'm on your side, believe it or not, Taurus Flyer.

I think the real problem is the remote needle valve feature, even if it isn't causing Crankpin's problems specifically. Heat transfer and additional air ingress points are part and parcel of this type of NVA. Notice that OS' latest two-stroke glow engine (IIRC), the OS.55AX, is equipped with a carb that has the needle valve back where it belongs.
