No allen head screws visible. Carb mounting gaskets are new, part of rebuild kit. I did find on the fuel distribution manifold a pinched outlet nipple. I have ordered a replacement manifold. I do not think one pinched outlet would not let the motor run. I did notice that the primer bulb will not get hard. It is a new bulb with old lines.I will replace the entire primer bulb configuration with new.
Will post again once I get new manifold.
thanks for the help to date
