Thank you to whoever suggested I soak the IP in automatic transmission fluid, I presume to swell the seals & stop the leaking at the cold start lever. I'm glad I got the suggestion before removing the IP, which I was preparing to do. I still have an electric fuel pump in line between the fuel filter & the IP. So, today (Sat.) I stuck the fuel line where it attaches to the fuel filter outlet into the fresh ATF fluid, ran the pump until I could see the red color of the ATF fluid in the IP return line. Then I turned the engine over for several seconds, hopefully to get the ATF fluid into all parts of the IP. Wondering how long I should let it set before the ATF fluid has minimum effect? It will have to set until at least Monday.
Second, refresh my mind. Does rotating the IP towards the engine advance or retard the timing? As I recall, someone said retarding the timing would improve fuel economy which is opposite the effect on a spark ignition engine.
