on a 6 cyl 280se that sat for years the pump plungers got stuck so fuel only came out of 3 pump fittings I sprayed carb cleaner and penetrating oil in the pump fittings rotated motor and forced air into the plungers if plungers are stuck up fuel can't go in or out. It took time but all 6 were working eventually. What are the steps to timing? Remove #1 fiting valve and spring fuel should flow till motor rotates to 24 btc?? It has been awhile. It needs to be drip timed?? Help I can't remember. It has to have fuel to #1 to time it. Does it??
