Listers,
In the last few weeks the 2 liter has been blowing an increased amount of
black smoke out the tailpipe during hard acceleration, and at idle I can
definitely sense the presence of fuel in the air. I checked the height of the
jets and they were within a turn of topping out lean. The slides are working
as intended. On a whim I turned the jets full up and the black smoke appeared
to diminish somewhat, but it's still pretty bad. I returned them to about 1.5
turns out and shut the car off.
Details: no smog equipment, needle type unknown, stock air cleaner, header.
I figure the throttle shafts are pretty loose in the throttle bodies, but that
would cause a lean condition instead of rich.
I guess I will pull out the needles and see what number they are. In the mean
time, what's the consensus on jet setting and what are the recommended needles
for a stock motor?
The timing is in the ballpark and the advance appears in spec with the tech
manual.
What do you have for me?
Thanks,
Mike
