its a manual throttle. she smokes white with a little dark at take off and for a while driving have not gone to a good grade yet small ones are slow to pick up speed.

How do I test the Fuel pump? and if it might be fuel I should also check air in take also right?

Thanks Rob

Screw a gauge in the secondary filter top if it reads 50 + lbs at full throttle you are good

Someone chime in here, you said the engine is slow to idle down, than indicates something is still wrong...

It's been sitting for 5 years all the linkage is stiff along with rack he just needs to change the oil, lube all linkage, add new fuel to the existing fuel and run the piss out of it for a few hundred miles it will get better with every mile

it will work. I would use it, if the price was right I am not partial to any oil, as long as it is CF2 rated in a DD.

i prefer Delo or Rotella.
