The 73 450sl started last night, 1st turn of the key. YAHOO
I did what I said, new vac line to MAP. New plugs. Gave the air slide valve a rap with a hammer. And WA LA.
Now with the dist. turned full cloclwise the timing is at 0 (TDC). That is the closest I have been able to get to 5* ATDC.
I turned the idle air mix screw out, to increase idle. Now here is a few more questions.
How do you test the, water temp sensor (EFI control).
And the Therm-o-time switch.
And the cold start valve. Are all these tested with resistance. What would be the OLHM value for each @ what temp.
Also to achive perfect timing 5*ATDC which way would I turn the rotor to retard it even more? Thanks again.
