Thank you Solomon

[@calrec1]

Nice tutorial on setting valves, George!

[@TheShadeTreeFixitMan]

Thank you sir!

[@wtbm123]

The blown fuse , wondering if it has a electric pto. If so may ohms check it , or check amp draw . Also most of those with electric pto will have a little harness . It plugs into tractor wiring , then other end into electric clutch . There is a diode in it . If that diode is blown , a lot of times it will blow the fuse at the moment you shut the pto OFF

[@TheShadeTreeFixitMan]

No electric pto on this one. I think one of the wires was bouncing around underneath. I have tied the loose wires up now. Thanks Terry

[@JoshKilen]

very nice runner.

[@TheShadeTreeFixitMan]

Thanks Josh

[@JoeG-firehousewhiskey]

I had no idea that those rocker arms being loose would have that effect on it!

[@TheShadeTreeFixitMan]

If the valves are too loose it makes for a very hard starting mower. Thanks Joe

[@normansmith7806]

Good job George !!

[@TheShadeTreeFixitMan]

Thank you kindly, Norman

[@N-Scale]

I knew you would get it George. Mike

[@TheShadeTreeFixitMan]

Perseverance, eh? Thanks Mike

[@MrLuka710]

Hi, I have Tecumseh 14hp OV490ea, i can't find a recommended valve clearence is also 0.004 mm for intake/exhaust valve. Thank you.

[@TheShadeTreeFixitMan]

Yes, both the intake and the exhaust are .004 clearance. Thanks for stopping by.

[@conlasmanosenlagrasa8727]

MUY BUEN TRABAJO 👍

[@TheShadeTreeFixitMan]

Thank you!

[@vojtaantusek]

Nice video. what is the valve clearance? Intake, exhasut? Tank you

[@TheShadeTreeFixitMan]

.004 on both intake and exhaust valve clearances. Thanks for stopping by.

[@ganakil]

are the nuts and keys in inches or millimeters?

[@TheShadeTreeFixitMan]

On this mower they are in inches thankfully. Thanks for stopping by.

[@ganakil]

​@@TheShadeTreeFixitMan thank you for the answer! From some youtube videos I came across the possibility of adjusting one valve at a time, the one that is fully closed when the other is fully open, without finding the TDC. Is this also a correct method or could I encounter some issues? To me, it seems like a safer method, but perhaps I’m wrong. I’ve noticed that sometimes the TDC has a brief moment, and I could face valve overlap or a valve opening for pressure release. I'm not expert, but I should check My tecumseh ohsk Valves Thank you, have a nice day!

[@Mike-vt6is]

Plastic weld 💯

[@TheShadeTreeFixitMan]

Thanks. We got it! This motor now resides in another state in another mower. There turned out to be an issue with the transmission on this mower.

[@whoolph]

Good job . . . . . Rog

[@TheShadeTreeFixitMan]

Thank you Rog

[@frios011]

ADJUST THOSE VALVES!

[@TheShadeTreeFixitMan]

Oh yeah! Thanks for stopping by

[@MissouriOldTimer]

just my opinion but I don't think ohv is a very good idea for lawnmowers, the regular old flat heads worked fine and usually not as much problems, I usually have the best luck with 2 part epoxy on plastic.

[@TheShadeTreeFixitMan]

Stay tuned for the welding video, and I agree with you on the small engines for lawnmowers and other goofy things (like carts...) Thanks Vernon

[@kenrichardson7542]

I have a 12.5 Tecumseh the flywheel turns a half turn then stops. I just changed the flywheel key too.Any suggestions?

[@TheShadeTreeFixitMan]

Have you taken the head off yet? You may have a stuck valve or even worse a broken piston. What happened when it quit running? That will give you a clue if you know the circumstance. If not, it is a process of elimination. Do the easiest things first. Pull the head, inspect the valves and try turning the motor while it is off. I expect you will see the problem. If the piston doesn't move when you turn the crank, you likely have a broken connecting rod. Hope this helps.

[@kenrichardson7542]

@@TheShadeTreeFixitMan Thank you for responding..Last season I rebuilt the carburetor and put in a new battery. I started it up this season, took it out for a warm up ride. There was a loud squeal (which I though might be a belt) which lasted only a couple seconds. Then a loud bang and then the machine stopped. I tried starting right then and nothing. I had to push it back to the shed....a mechanic friend of mine said broken piston.....do you have a removing the head and fixing a piston video?? lol (my lawn is getting taller by the day!)

[@dirtytsfarm2141]

I know this is a yr old vid, but I want to put this out so that it may help someone to avoid doing what I did. Check the peripheral attachments on the equipment. I once had a buddy's mower doin the same thing with the flywheel. Could only rotate the engine a little bit back and forth and it would lock up. I was thinking something in the guts of the engine was grenaded so I started taking off the valve cover. As I'm doin this my buddy & I are talking and he says "the blades are always engaged, been like that since I got it from my dad". Sure enough, broken blade engagement cable. Doin the deck inspection I found one of the spindles to be completely locked up. So the belt always being engaged to that pulley was why the engine could only turn partway. I put the valve cover back on, pulled the deck belt off the engine pulley and it fired right up and purred. Not sure what your machine is, but I learned a valuable lesson that day about troubleshooting. It ain't always the engine lol!

[@grant.m.ball0603]

Is that the mower that was at your house when you first moved there?

[@TheShadeTreeFixitMan]

Yes sir it is and now it is running and mowing. Thanks Grant

[@deltabravo58]

02:34 Gesundheit!

[@TheShadeTreeFixitMan]

Thank you, and thanks for stopping by.

[@rustyrods8535]

Could I be 1st George .....that would be a 1st .

[@TheShadeTreeFixitMan]

Perhaps you are? Glad to have you here!

[@LVBeatzMusic]

tecumseh pretty much copied an older briggs model 31. XD

[@TheShadeTreeFixitMan]

These motors are all very similar. Thanks for stopping by

[@LVBeatzMusic]

your welcome!!

[@vomitokilleur]

hello the gap at the rocker arm are 0.004 for both?

[@TheShadeTreeFixitMan]

That is what I found when looking for the proper specifications. Thanks for stopping by.
