Hi,
Thanks for all of the great ideas re: 300D fuel starvation. Does anyone have any experience with what would happen if the fuel overflow valve or circuit were clogged?
The car starts well hot and cold (25 degrees this morning without being plugged in) and idles very well. The power is good up to 2500 rpm and then goes soft.

The entire fuel system is dry and without any apparent leaks. When I replaced the spin-on fuel filter, I installed a NAPA Gold and filled it with Redline before installing it. I didn't disturb the hand pump... I just started the car and it roared to life. Everything is dry so I don't believe I have any leaks.

BTW, the smoke is whitish gray and is more visible the farther I drive the car i.e. it is ok on my street, but 1 mile away it gets worse. (This on an already warm engine.)

Does this sound like a clogged fuel overflow valve? Thanks in advance.
