We had a crapload of fun with motorized toys while I was growing up.
Using our Dads Jeep Overland Wagon while he was a work, to tow an engineless Fiat 850 to the top of the mountains behind our house (it was all national forest then), put on our motorcycle helmets and blast down the mountain over bushes creeks and rocks all the way to the bottom.
Then tow it back up and do it again.
I can't begin to tell you how many times we crawled out of it while it was on it's roof.
When it was winter we used that same Jeep to tow old car and truck hoods up there for everyone to ride them down the hill.
I was the oldest at about 12, so everyone else was close or younger.
Can you imagine 7-8 kids that young taking a 4x4 off into the national forest in the winter by themselves these days?:D
Todays young people have no idea what kids were allowed and capable of doing back then.
I was driving caterpillars and wheeled tractors and my Dads road grader before I was 12.
Not to mention all the trucks cars and other equipment.
Ever seen a four stroke single cylinder Fairbanks Morse engine? (one of my favorite toys back then)
You put a 12ga blank in the hole and put the cap on, then turn the motor over to just past TDC and smack the cap with a hammer to fire off the 12ga round and that would start it turning.
A quick shot of gas in the intake with an oil squirt can and off it went.
Thump,,,Thump,,,Thump,,,Thump up to it's approximate 1,200 RPM max and then fire about every third time the piston came up after that if not under a load.
