I have a new set of filters on order from you guys and am going change them first. The air filter in it is quite dark.

I have taken the snorkel off the turbo, it turns but doesn't truly spin to the touch.
Thanks
It starts, doesn't smoke. Seems to get about 30 mpg. I figure that with the injectors being over 7 years old, maybe 27 years old, they could well be part of the problem. Not that I need a car that goes that fast but just wanting the most efficiency as possible.

OK, some possible issues.

Biodiesel has a lower BTU per gallon compared to DIESEL.
You can spike your tank with 4oz - 16oz of 2 stroke oil for more power.
