check to make shore that the fuel lines aren't braking down on the inside and check fuel pump timing advance to make sure that the waights aren't broke, an check the stop screw to make sure that it is set so that the pin isn't coming out to fare.

3406c...oil leak @ the [p/n 7c-0942] adapter plate above the inj. pump. does the front housing have to be removed to replace the gasket and o rings on the adapter?
