Bosch Electronic ignition timing way off
I've installed a new (Centerline) distributor. Generally on a 4 cylinder engine, when the timing is near optimum the engine speeds up. However, this occurs near the maximum advance mark "M" on the pulley. When I retired the timing to the "P" mark (or "F") mark the engine slows down. Blipping the throttle the engine is sluggish, reving up slowly. It revs up quickly at the "M" mark.
Distributor is inserted properly (it can only go in one way)
Rotor is pointing to the number 1 cylinder. (I verified that the number 1 was on TDC - "P" mark, by removing the spark plugs and noting the valves were closed and the piston was at the top.)
I'm at a loss...any ideas?
