What you have is a dual diaphragm distributor advance, the outer hose should be hooked to ported carburetor vacuum for advance under load conditions, the inner diaphragm uses intake manifold vacuum to provide timing retard during closed throttle and idle to reduce emisions, most people just plug the retard (inner) hose and run without it. Either way you must disconnect and plug all vac. lines to the distributor when setting timing. If you installed the rockers by just tightening them down then you have hydraulic lifters because if they were solids your pushrods would be all bent and the engine wouldn't run for the rocker adjustment is a critical step by step procedure with mech. cams. The backfire at high RPM sounds like timing too advanced. |
