Some time ago the members here assisted me with a fuel pump issue when I was decarbonising my LD1. Well, another issue has arisen which you might be able to help with.
The engine is now in the boat and starts/runs smoothly but unfortunately only at about 580 rpm. The plate indicates she should do 1500 rpm. The speed control rod has little or no impact on the revs. When the knob is turned back from 'start' to 'run', the revs drop away and it will eventually stall. I've checked that the link spring from the rod is intact and in place, and followed the fuel pump setting procedure as per the instruction manual (P35).
Before I start pulling the timing cover off to check the governor assembly (pushing the envelope as far as I'm concerned), I thought I seek some group guidance.
Any ideas?
