Brain teaser for GW

[chuck giacobbe]

blaine gem made an adapter plate for the mac 30 and mac 40 intake for single hl carbs.

Why would GEM or anyone make a single carb adapter plate for a Mc 30 intake manifold? It came from McCulloch as a single carb setup with stud spacing for the flatback which is the same as the Tilly HL series. Maybe you are thinking of the dual carb adapter Agricast made for the 30 manifold???
Do you have a picture of the GEM part that goes on the Mc 30 base? Maybe they made a piece that eliminated the third port passage and forced all incoming charge to go through the reeds so the manifold could be used on a 9 ported engine???

The photos posted above are of a Mc40/70 dual carb manifold with the single carb adapter installed. That is not the same base as the 30 version.
