Doug, an easy way to cut a hole in the piece of sandpaper is to fold it into quarters and cut that inside corner off. Easy peasey! 😉👍🔧

[@horserider9578]

Love the way things don't go exactly right things knocked over ect just the way it happens to me keep making them videos .

You might be an amateur poor man but you’re rich at heart.

[@myles5276]

This has given me some insight on my 1945 wisconsin so thank you very much.

[@Adam-en4zm]

Thanks for the video, this is gonna help me fix a snapped valve in my Onan 6.5kW marine genset. Luckily it has adjustable tappets, so it's a bit easier to get tuned up just right. I enjoy your videos, you got a sense of humor, and you speak to a fellow poor man mechanic, haha.

[@philliphall5198]

That’s a good way to grind the stems Beats using a bench grinder for sure Good job 👏

[@wannawin95]

Last time I was this early, Tecumseh was still making engines

[@shawngoldsberry747]

Was an engine

[@stevemorris2493]

Good stuff! Keep it up! Update often!🎉

[@outdoorsmansgarage]

Dang you sure are taking your time on it.... 😁🤘

[@davidausburn1552]

Hey bud, next time your lapping a under size valve just go grab one of the kids nerf darts. Works great

[@DougvCarburetor]

WOW... That is an amazing tip. Wish I had thought of it. thank you!

[@sccarguy8242]

Another chunk of iron kept from the scrapyard. She loves to thump another day !

[@marshallborder9089]

Good job . Thanks for showing how too use the value spring compressior tool , I've done a lot of value jobs but only too use a screwdriver. I got valve spring tool given too me . ( yes the hard way I know) I'll comeback too your-video when I use it next time - for the first time .

[@stanleyshults6427]

U never tried seat face in block,such a waste,also u need to update spring compressor,,can be done with one hand,spring remover,in less than 30 seconds

[@dfields9511]

gr8 vid,, I think I am going to have to do this on a Briggs quantum 190cc on a lawnmower. It seems to loose compression when hot and will not start

[@jesserousseau2481]

This is a great video.

[@1stzjtruck706]

Very nice job

[@JorgeVonVogler]

Sweet dude want to do this on a old Tecumseh eager 1

[@kmweek]

That is really poor man dude, good video though. Good job.

[@frankdavidson9675]

he got it running thats big

never saw anyone do a valve seat with sand paper. i have a small tub of valve grinding compound i have had for over 30 years and i have used not much at all. i just put a little on my finger and spread it around the valve seat then install the valve and spin it a few times then clean everything off real well and i am done. i bought a pinto back in 1986 that had a miss due to a valve leak. that is when i bought the grinding compound. i have done maybe a dozen engines over the years, mostly small ones like a motorcycle or atv or such. i have never had any issues with any of the engines i did. i have never used the rubber tool you twist the valves with either. all engines were overhead valve engines so i just took a drill and chucked the stem in it and spun it that way. now with a valve in the block engine obviously that would not work but i have yet to do any.

[@kenbell9564]

Wow, Where are your tools! Keep up the good vids! Ken

[@suttonbogedain5874]

Thanks. Helpful.

[@Kim-lc2uq]

Usually find myself without the right fixit stuff or tools, glad I am not alone! Good tips on gittin er done, enjoyed the video, moved along nicely.

[@philliphall5198]

Take a string and wrap around stem and work it back and forth It’s better than finger turning it

[@robertgrauman8602]

I remember when I lapped the valves on my 5.2 rebuild I watched a video where the guy described it just like you did but with the lapping tool. Only difference was he said to going until you hear the pitch change as you're lapping. Once you here the pitch change you stop and check the valve and seat. Repeat if necessary. Then again this could be the procedure for hardened seats.

[@timzyaboi3784]

Yea, that is a good rule of thumb when you have the speed of the lapping tool on your side. I do not think there is any issue with how Doug did it here though.

[@robertgrauman8602]

@@timzyaboi3784 I agree, I just don't know if the same rules apply to small engines and valve seats that aren't hardened.

[@davidnadeau9460]

You should gap valves closer to the maximum tolerances 8 thousand inch rather than close to the minimum spec. The fact is it don't much matter if it clap a little, but matter much if the valves wouldn't close tight. And the other fact specially in exhaust valve is they expand with heat. And last on these tecumseh it's between 8 to 12 thousands an inch in the specs for both intake and exhause. 2 thousands is too tight maybe it's not the same engine specs but i would go closer to 8 thousand anyway since valve seat will use a little and get closer and closer, it will last longer at 8 thousand.

[@frankdavidson9675]

never did use the wooden valve grinder sand paper is a no no need to grind valve and seat at same time with compound and wooden grindert ween both hands

[@eddymumford4086]

i don't like the new head gaskets ... you can't take it back off

[@kober2118]

What about the valve guides?

[@lukek6492]

Hi. I have a very similar engine ... basically same one but newer I did a valve job on it. And now i am getting alot of oil coming out of the valve cover... Alot more then before any idea why thats happening.????

[@solidjockey2963]

Gotta make sure they are SGT spec! SGT = Standard German Torque = Gutentite.

[@zanebeasley6246]

Enjoy the video

[@RandomQualityGaming]

I have one of these engines and it idles but it stalls when I accelerate. could the valves have something to do with it?

[@eddymumford4086]

fire it up ... fire it up

[@balanionut8863]

Hii, are those mesure blades in mm? Could you tell me in comment what size should be the gap? Thanks a lot

[@kmweek]

They are both metric and imperial equivalent feeler gauges

[@johnkomosa9508]

Intake 8 thousands exhaust 12 thousands valve stem gap.

[@alejandrosasing1292]

How much valve clearance for intake and exhaust valve

[@jeffreyyoung4104]

I use .008 on intake, and .013 exhaust. The stems don't stretch, but the face and seat wear and the gap gets smaller.

[@ethanshelton2763]

Get ya sone duck tape and cut ya a strip off ball it up with the sticky side make it about goofball size and you’re good to go works better then and hand valve

[@adammosher5818]

Can you do this with out shaving the valve

[@J.E.Taylor]

No.

[@adammosher5818]

@@J.E.Taylor ok thanks for the info on it

[@frankdavidson9675]

the valve and seat have form an air tight seal no leaks remember no compression with a leaky valve need take a comprssion check after you pu tthe head on to see if any leaks anything below 100psi is a leak prob.

[@TheUltimate65]

Ohhh my gad,,whay not use the valvesanding tool...🙃

[@squirrel1179]

You ever find yourself in that position again try a wooden dowl an some hot glue.

[@brianp9115]

A “real” video

[@kmweek]

Time to clean up that work counter of your 1 x 30 sander.

[@robertbain2653]

Why do you keep throwing things big turn off

[@frankdavidson9675]

hes in a hurry to get thru with it .

[@moderndaycowgirl9219]

Not wd40

[@rpiercebutler]

my fathe rused to lap valves. All he accomplished is ruining valves and valve seats. Onan specificilly states in the manual "NEVER LAP VALVES" all it does is wear the valve seat and creates too wide a margin on the valve sealing surface.
