Well here's the problem, when it trys to play it
will engage and everything goes into place fine (checked and all looks good)
and the idler will go to the supply rell, but it moves very slow and jerky
and then after 2 seconds shuts it's self off.

Check the movement of the capstan motor. If it's erratic, you might want to
check the electrolytics on the capstan motor assembly. You'll also want to
replace the mode switch if you cannot dismantle it and clean it completely of
any corrosion. Hitachi mode switches are real nasty about causing big
functional problems when they are worn out or severely corroded, like having a
Hitachi VCR act partially braindead because of a non-functioning mode switch!
