The adapter plat is epoxied onto the cut manifold & thru screwed where the manifold studs were. a couple are under the carb so I used flat head SS screws there. It sealed right 1st try & ran 1st try. Next is going to be a V block reed set up but that will be more difficult. When done it will drastically reduce crank case volume & eliminate the pre historic 'wall' of reed obstruction.
