Its a lighter green than the Screamin' Jimmy, over the years Ive seen many engines this color but no rebuilder tag......
The old gal is starting to pick-up #4, 35 years of stitting has simply stuck some rings I think.
Every time I run the truck up to temp I remove #4 plug and spray in WD-40 at shut down, seems to be helping.
Keep'em Rolling, Gang!
