Look for a hole in the saw body for a set screw. Twice the set screw stripped on me so never actually got the bearing out. If you do get the set screw out, look inside for another one in case it's doubled up

Didn't have any problem using carb cleaner. Used it to clean out the old gas and oil residue inside the tank of mine. BUT, I didn't leave it sit in there for a very long period of time either, probably less than hour or so total. Then blew it out to evaporate what was leftover too

The line goes straight down and has one of those cone type filters with a screen on it on the end. The cone is too large to fit out of the fill tube too. Mine was broken off so to repair it a hole was drilled in the tank but on the opposite side of where I marked in the pic. The only solution to fix it so... The circle cutout was glued back in using Seal All. Undetectable unless the engine is removed. Is it clogged? Best to work on it slowly soaking carb cleaner in it until it loosens up if so.

A blow torch Another nice score

O&Rs look cool on those little mowers. Good to see everyone building stuff with them too. If you can't find it, make one!

Bet he wants it back now

That's awesome! Looks like it belongs on there. 20 years from now some O&R collector is going to be looking and searching for another one. Good thing the hunt is half the fun.

Pulled the wheels off to do some more work on the little bike. Here's the divot in the tire from the first video when it didn't have enough friction. It doesn't look that deep in the pic but it shaved off a good amount. Too bad it didn't create any smoke or I would do a video of burning out that whole tire.

Believe it or not, that's part of the reason I wanted to run it. Doing strange stuff is part of the fun. The neighbors already think I'm nuts so going down the street with a fan and a bicycle would just be par for the coarse around here. It doesn't really blow with the force I expected but definitely moves a good volume of air.

The problem I had was separating the generator halves to get inside of that section for cleaning and repairs. That set up with the clutch connection will let it separate and go back together very easily. Not sure it really needs to come apart but just in case you wanted to open up the engine.

Got the fan all cleaned up and did the carb but then just wanted to see, hear and feel it run. Still need to do a yellow tank and the fuel line IMG_0665(1).MOV

Curious why you think it may be a replacement engine vs original to the fan? The Industrial decal? I don't have many or know much about the newer 13B engines as I prefer the older engines

Sorry David, I missed this but here they are. I don't remember ever seeing this style recoil decal before. Nothing seems any different to make it an "Industrial" engine but it hasn't been disassembled either. And not sure I'm even going to since it has great compression now, the flywheel and all the grooves in the plate are clean. It has definitely been run before but with no build up of debris on the flywheel from sucking in air, it indicates a low hour run time. Think it just needs some overall cleaning and the carb done. The plan is to just clean it up a bit and let it fly it's character as it was used by the LAFD. I was going to paint the grills as the chrome on them isn't the best but leaving it in it's working clothes is the best option for this one IMO.

It's my opinion it would be fine with the new gasket material. Especially for the little one between the carb body and diaphragm as the thickness shouldn't effect anything as long as it's not too thin. The only issue with the others could be the governor touching the exhaust manifold but using 3 instead of 2 gaskets should cure that. Thicker would be better than thinner for that spot. I've used thick cork gasket material in the past for the carb to case gasket and the engine ran fine

Hmmm, David does have that mini bike now so........ Come on David, ride that thing and share a video!

Ha, that's funny as I was think'n the same thing! He must be up to something Yeah, I cheated a little but when the friction wheel wasn't as tight and starting from a dead stop, it chewed a nice deep divot into the tire at that particular spot. It would go better now doing that but it would still be a very slow take off.

Couldn't resist the urge to go out and tinker again after seeing Terry @JUST O&R on that skateboard. That was great stuff and glad we finally wore you down to go out and give it a try. So, Got'er some more friction with a big azz spring and some more tire pressure. It won't carry me up the slight incline that well but gets moving going down. The biggest thing I noticed was my ever increasing bald spot. The ball's in someone else's court now!

Sometime? Now all the video pressure is on you. Looks like Terry beat my land speed record so I'll get the bike tuned for the street and give it another go this weekend

Bravo! I was hoping that challenge would get ya on it. That's good stuff! But I thought you were going stand up on it and do some skateboarding tricks like this. Alright Clint, get your man hole fan out, it's your turn

Easier to just sell the plans and let the other tinkerers have at it but I'll see if I can make a nice pipe bender to more easily reproduce exact copies.

It was hard to stay upright going that slow, hence all the steering back and forth. The wife was laughing when she watched it too but said she would video one so you guys can see the bike better. Maybe I'll try again after getting some better friction but I'm guessing this design isn't for an adult to ride. LoL

You're on a roll again Maybe some day we should all compare ours books and update any missing portions or bulletins. Pretty sure David and Terry have one as well

OK, went for the crazy daredevil ride of a lifetime. Check out the risky off roading over the grass! Youtube was a pita so shortened it to copy directly. Hopefully you guys can view the video but let me know if you can't. Just threw some stuff on it so I could ride it and thought it would be funny. Still have lots to do but doubtful I'll ride it after it's done and painted. Now it's Terry's turn for that skateboard IMG_0659.MOV Had some traction issue with the friction wheel. I'll figure out how to crank that down so it bites into the tire better. You can see it peeling the tire in the pic with all that black on the frame.

Another nice find. Those things have some interesting engineering on them

Take it you found one. You can do your own thread if you want. It's up to you
