fyi The engines were warranted for life if you had them serviced @ the dealer

Older two strokes were messy but they are cheaper to manufacture and some folks
like them as they are always lubricated since you mix the oil with the fuel.
Most modern two stroke oils allow for a 50-1 mix and this provides less carbon
buildup in the exhaust and less smoke. When I first got my little NC50 Honda
Express going again, I used that mix in it until I could repair the oil pump and
it worked just fine. I have many toys that use 2 stroke, weedwackers, hedge
clippers, chainsaws and even a small generator. With proper maintenance they
are fine reliable machines. I even had a 61 Saab that had a 3 cylinder 2 stroke
engine.

When I was buying my 70, Dad wanted me to get a Vespa scooter 150cc two stroke.
But Mom intervened saying that she had seen many people with stalled scooters.
I wonder how those spark plugs keep working amidst so much carbon and black goo.
