Running Lean, Suggestions Options

[BMartin914]

I've got a '74 2.0 engine with d-jet that is running lean. Biggest indications are whitish plugs and high oil temps - about 240-250 after highway cruising in 90-95 degree weather (very little humidity). While moving oil is about 230-235, but when stopped or considerably slowed, temps rise to about 245-250. Cyl head temps will stay a consistent 300-325.

I have switched out 3 good MPSs. 2 049s and an 037. I cannot seem to find an 043, but thought that at least with the 037 I would see some difference in running condition. I have also switched out 2 TS2 sensors with no difference in plug color or oil temps. I plan on trying to retard my timing some, check fuel pressure and replace filter tonight. Possibly bump pressure up to 32-34 psi.

Short of dyno'ing the car (which I cannot afford to do at the moment) does anyone have any suggestions for richening up the mixture?

I am considering a pot on the TS2 sensor. But that would only be if nothing else works.

Additionally, I do not seem to have a sock strainer in my tank. Where should this strainer be and is it possible to simply drop one in? Just noticed this late last night.

TIA

... PO had his mechanic re-time and adjust MPS. Leaned out car to pass.

i know you said you swapped in several MPS's but a statement like "adjusted the MPS" always scares the sh!t outta me. i know the kind of equipment and experience you have to have to do that right...

i do think you'd be well-served to get some better AFR measuring instrumentation, but i understand the difficulty. it *is* possible that you are running so far lean of peak that the CHT is cold again...

getting a pressure gauge on the fuel rail is an excellent idea.

good luck; i know what it's like to be in the wilderness with few knowledgeable resources to lean on...
