Hello, just recently picked up a Fieldmarshal 12/2 with a Powersolutions gen head. I got it from my neighbor who is currently downsizing his life. Its been sitting for many years in his shop. Got it back to the shop and aside from needing some cleanup and maintenance it appears good. Two questions for those who can answer. I was wanting a little schematic of the genhead if anyone has one. Its a 7.5 KW 1800 rpm. Its beastly large. My neighbor never actually used this whole setup much. He took the cover off the head and wired one outlet to it and ran a fan occasionally.....wow!... anyway... I was also wondering if anyone knows of an oil filter conversion that works on this engine? Its a 12/2 as stated but I can't seem to find much about it. It seems the twin cylinder model wasn't or isn't as popular as the single cylinder. That's all. Thanks for any input here I appreciate it.
