I really don't wanna get into this but imajine being a dad and finding his sond has to get his leg amputated because a rod blew into his leg :shrug: because a kid will read this and think oh so if I take my gov out I can race and hold it open, also no offence but phil said no hard feeling, he didn't mean to say anything against you, but again most of use on here no a little more about motors than your common joe,//// also if yor rebuilding the engine just get new rod bolts and save your self some throble:thumbsup:
Save trouble? good luck finding just rod bolts for a stock flathead rod, especially these days. I don't think they even sold them seperate ever.
And you have got to be on crack if you think someone is going to get a leg amputated by a blown rod. Thats absurd.
I'm 41, I've had access to thousands of small engines, I've blown hundreds up on purpose. I started when I was 8 years old, on a lawn mower, WITH A BLADE!!!
The worst thing I ever had happen was a horstman H beam rod come out of my engine at full speed, at elbow length away.
Do you know what it takes to throw a horstman h beam out of your engine? I mean out out. Guess what injury I recieved? Nothing.
Second worse. Me and my brother took an air compressor connected it to a 3hp removed the head to watch the pistons go up and down. Well that got boring so we swapped the big pulley onto the engine and small pulley onto the compressor. Long story short a rod let go and the piston shot into the sky. We never found it. I might be lucky I don't have a piston imbedded in my skull today, but thank god back then I wasn't dumb enough to put my face over it.
Sorry OP.
This seems to happen all too often with my posts. I need to focus on getting OldMiniBikes to ban Predator engines because they don't belong on vehicles.
No hard feelings, just everyone tells me a flathead flywheel is going to amputate some poor kid over and over and over.
Well I've made it from age 8 to age 41 and never had a flywheel of anykind blow up on me. Yes, I've even put those aluminum lawn mower flywheels on a 5hp flathead. Grenades, yet I never had one blow up. Some people can fall off a ladder and break their neck screwing in a light bulb too. The world is a dangerous place, better throw your hobbies away, they might kill you.
Oh get your OldMiniBikes billet though. The sales pitch thats been sucessfully beaten into everyones head on this site.
Amputation from a connecting rod, holy shit I've heard it all now.
