Well, im sure many of you have seen my 1973 Jonh Deere 70 puller.
Well, i was pulling around 2000 pounds on a stone boat in my backyard.
I was in second gear, around half throttle
No problem with power, couldnt even tell it was back there.
Now here's where things get weird.
It was doing a wheelie, and fell right on its face.
It made a sound, something like a blow off valve on a turbo, and lost all of its power.
I thought i blew a head gasket, i was wrong.
It started up again fine, and was running with full power like normal.
Everything was fine, but my question to you is, why would it do that?
My only guess, since it wasnt the head gasket, is a valve got stuck open?
Till them, keep 'em cranking
