I have burned 100LL in everything from an antique Curtis 0X-5 to chainsaws with no problem. He agreed that it should be ok as he only had 5 miles to get home. We put in 2 gallons and off he went.
Later that evening he called and told me what happened. After about 3 miles the engine stared heating up and missing, by the time he got home it was running on 2 cylinders with a blown head gasket. He was pulling the head last night so I hope that was the only damage.
My question is do any of you petro chemical engineers have any ideas as to why 100LL would cause this or was it just a coincidence?
Have you ever seen "The beverly Hillbillies"? They always used alchole!
