Engine has sat idle for 3 years, still good to go?
I haven't been on this site for about 3 years.
A few weeks ago I dug up my old HPI R40 with a JP Modified RS12 (black with purple heatsink).
The last time I ran this was maybe 6 years ago. If I remember correctly, I ran the car and just stored it (without any AR oil, yes, rookie move).
What are the chances that this engine is still in good shape?
