How does it run?
After sitting for 6 years, it will run rough a while but should smooth out after running a few hundred miles with new engine and xmission oil.
Flush engine oil with MOTOR MEDIC GUNK to get rid of any oil slush, carbon deposit and corrosion in moving parts. Drain and replace xmission oil, flush if necessary..
Run the engine easy for a while. Don't push it.
if it does not run smooth after a few hundred miles and has any bad symptoms, we can help you troubleshoot.
