Spent this afternoon reassembling my 70cc bike engine. It was time for new piston so I decided to tear it down completely, found that the output side crank seal was destroyed. One new piston kit, seal & gasket set later and it's running better than it ever has. Also went and case matched the transfers since I was in there.

Coolant bypass valve on the Jetta today. Had a crack in it. Not a bad repair, pretty clean and easy. The bung at the bottom is the coolant temp sensor, thought it was the o-ring, happened to be the manifold was cracked across the topside.
Also put new blades and a new belt on the lawn tractor today. Finished the lawn. At least a couple things off the bucket list.
To a point, yes but none of it would have happened if the F-up didn't happen in the first place. I'd call it a mix of blame here but way more towards the guy that worked on it.
Her's a story that's kinda related I was part of.
Years ago in one of the DC's I worked at we had a guy that was always screwing up, upper management (Dept head) was always covering his ass (Ass Kisser) but it finally caught up with him. He had replaced a drive tire on a manup and the operator was of course using it. While way up in the air it suddenly "Dropped" to the floor and that's what happened, the drive tire came off and obviously the operator shat their pants too.
Anyway, since he wasn't there himself when it happened I got the nod to find out what happened and why. Found that the tire had come off and the lug bolts had worked loose causing it to do that - My shift manager wasn't happy at all since it constituted a safety issue. It was something the dept manager coudn't cover and he got his ass burned. His excuse was "I didn't have a torque wrench to properly tighten the bolts" and it was asked that if he didn't have it, why did he do the job anyway and send it out? Hmmm....
BTW using a torque wrench on those is bullshit, although it IS in the manual I've never seen anyone do it, never did it myself either and never had a problem. We always did them like lugnuts, make sure to get them good-n-tight and let 'em go - He didn't do that as in left them loose in the first place. So he got canned.
And it wasn't long after that the dept head started messing with me.
They had the balls to do a writeup based on PM work I hadn't even done yet for the month (I had the paperwork to prove it too) but they claimed because I did it (Which I didn't) it had caused a problem with a drive unit in one of the trucks. Nevertheless I walked out after my manager was through with me over it on the spot - Left a reach truck scattered all in pieces in the shop too along with a few other things. I didn't blame him because I knew where it was coming from, I sent word back through the cleaning ladies that stopped me at the front door as I was leaving so he'd at least know that. I also knew if he didn't do the writeup as he was told to do they be on him.
He knew himself it was bullshit but coudn't say it was so for obvious reasons.
Guys I was so mad I was literally seeing red all the way out and it took about 4-5 minutes to do that, from shop to front door. Didn't have a job for about 8 weeks after that but I still don't regret it one bit to this day.
BTW that dept head finally got his (Busted) later for stealing from the company, over 90,000 worth of parts they found at his home when it was searched including a golf cart and alot of other stuff.
My neighbours ute went to the local dealer for head damage. $1500AU repair. Lasted about 1 month before it stuffed up again.
What the neighbour did not know. I talked to an ex employee of that place, apprentice with bad attitude. Bad attitude because he was fired OR bad attitude in general. I think the latter Cranky shit, bet he worked on it.

@mr.Scott the truck will run 30 seconds every key on. When I arrived it was completely derated, so you get only 5% torque. The motor smoked when it dumped most of the oil pulling the load at 45mph. He was 2 blocks from the stop. Did not admit, but probably started the truck at least twice to get the freight to the customer. Funny part is, the company doesn't want to sacrifice a truck for on time delivery, but if that's what it takes to keep a customer......
Bones, that story sucks, but I fully understand it. Gotta admit I started the motor and moved the tractor 20 feet. Had to pull it out from under the trailer. Boss figured I smoked the motor until the other lead tech and I discussed this situation. Yea, I shouldn't have started it. Was the initial damage caused from my decision? No way. That bearing spun because the driver made it to the stop with no oil.
@avalanche The driver is not really at fault. The Tech made the mistake. Drivers shouldn't have to worry about the oil drain plug. Shit half our drivers don't even know the truck has one lol.
Not sure if it fits here, but I love everything that combines physics and mechanics and takes them to the extreme. So naturally high power engines are high on my list.
Anyway I stumbled upon this:
How cool would that be, to use one of those in a watercooling loop. You'd probably need a super high pressure pump and fans and it would not even be as efficient as regular radiators designed for lower heat applications BUT it would be a friggin Formula 1 part on your PC

I just ran across this -Interesting! I've heard of other things that's similar to it in that it just works, currently have the carbs from my bike soaking in Berryman's. If I had known this yesterday afternoon I'd gone with this instead of spending the bucks for the chem dip stuff. advrider.com/f/threads/the-pine-sol-degreaser-thread.560117/
With the above I decided to give it a shot but also wanted something else, namely to create a sort of ultrasonic cleaner container to help it. Since those are really simple in how they are I went to WalMart, bought what I needed and cooked up what I wanted, E-Z-P-Z.
The container I was using to soak the carbs just wasn't deep enough but this one is, made sure of it when I got it.
The following are pics of the carb after sitting in the Berryman's overnight, how it was when removed and so on. I also show what I got along with what I already had onhand to make it with, namely the little motor, power supply and Gorilla tape.
In this last pic, if you'll look closely you'll see what looks like tiny "Streams" of bubbles coming up through the cleaning mix indicating it's actually working.
Going to let it soak all day and see what it does, when I take it out I'll show what it did if anything. BTW I will disassemble the carb anyway to make sure it's fine, the concretion in the jets are cleared and so on, then reassemble and reinstall the carbs on the bike.

Hey Rodney that's good stuff!!
Right now I'm converting the motor from the mini bike to a Yerf Dog go cart I picked up cheap. The carburetor keeps getting clogged by the fuel shut off which has a rubber grommet thats deteriorating. Might have to try soaking the carb like you're doing here, but it's a very small carb. So a good soaking should help it.
Thanks for this post!!
PS, I'll have some pictures up at some point. Removed the rear axle and welded the drive gear on already. Now to mount the motor.
ArGone tank for 20 cubic feet cost me 135$. (mini tank)
I hope it turns out well. Superglued a screw to the end of the motor to induce a little more vibration, not by alot but it's there. Had to slow it down due to it making to motor complain with weird noises but set the voltage for 6v and it smoothed out, getting plenty of vibration now without stressing the motor. Had it at 9v before and yes, the little motor was letting me know it didn't like it! I can feel it quite well back to the trailer's fender so I know the vibrational intensity is good enough.
Will let it run all day as said and go from there.
