I'm also converting this one to reed operation. It won't be by adding a reed assembly at the side port intake, that has been plugged. The reed intake will be at the bottom of the case.

When I modify, no half measures, I MODIFY.

And as the pictures show, I'll be using a stock, RC throttle instead of the Walbro. This one is off of a K&B Sporster .60 and the bore of both rotary barrels is the same.

I'm very new getting back to big gassers so I don't know the latest. I noticed that the Walbro that came with the Tanaka has a rotary barrel along with a needle that restricts fuel delivery as the throttle is reduced. Very much like our RC throttles although the low speed needle appears not to be adjustable. Is this unusual or is this the norm these days?
