How to perform a crankcase pressure and vacuum test... The 084 wet shot saw progress... Head is on 💯

[@jerseyjoshua4818]

I don't believe a WORD YOU SAY! Fabz told me so. You have certifications & a devoted following. He on the other hand has many videos blasting some guy named "Johnny Nitro" and preaches you DON'T need compression in a 2-stroke. Because it KILLS the saw! I'm inclined to believe and trust a person with less experience & is a blowhard, than yourself. My advice GET ON HIS LEVEL.... ROOKIE!. (Remember to laugh after reading this 😂)

[@johnscustomsaws]

Damn... he totally has me backed into a corner😳. ive been exposed 😫

[@jerseyjoshua4818]

I don't mean ton stoke the fires or start an onslaught of drama. I'm glad you decided to focus on your own lane and have fun with your channel as a learning tool for others. The saw community is VERY finicky about things. Opinions & Assholes are one in the same..... some are dirty & full of shit, while others are fine enough to share the same toilet. Get what sayin'. Stay rowdy, Stay building!

Great video as always! The cussing and small engines are tied together. One day the preacher was working on a lawnmower when a little boy walked up to see what he was doing.After several pulls it still wouldn’t crank.The little boy told the preacher “you have to cuss it to get it to crank”. The preacher replied “Son you don’t understand I am a man of God ,I don’t cuss.” The little boy replied” Keep working on it ,You will!” 😁

Awesome channel wish john was still making videos

[@tylerheard1279]

I absolutely love the info vods man! Lots of knowledge to share in your brain.

[@Ralf1erudd]

Thanks for your work. Very helpful. Been working on engines for about 60 years and still learning. Great stuff

[@paulborden2544]

Good video never seen water trick.

[@JustMe-gw3eo]

I dig it

[@littlemechanicshop]

Pressure/ vac test is a must. There are so called saw builder on KZbin that don’t even test after assembly. And they fight and fight a bad running saw and would found the problem in 5-10 min. Pressure/vac test is like the 3rd or 4th thing on the STIHL check list. One day I hope to get one of you’re 500i or 462 in my hands.

[@Yamikeylikesit70]

Just rebuilt an 039 the other day and as always I pressure tested it before I completely reassembled it. Good thing too because the new cylinder had a crack that went completely through. Took forever to find that leak.

[@markcdeyoung3118]

Mighty Vac sounding more like mighty dog having a sneezing fit .. after sniffin' some black pepper 😅

[@bigstuff52]

I learned a ton..Thanks for uploading..Very professional video..

[@ratboyiscool]

Hey John been through a small catalog of your videos at this point. Wicked explanations, really appreciate you sharing the knowledge!

[@philliphall5198]

I’m sure you know what you’re talking about and I enjoy listening plus learning the correct way to do it Really there’s only one way and it’s the right way Thank you for information and advice

[@cipriandenes6641]

BRAVO !!! Alt nivel !!! Multumim !!!❤

[@mfsaws8240]

I can’t take you serious with the Fu Manchu haha. Great videos glad your back

[@kowski9477]

I guess I never knew about the spark plug ring leaking . Good to know. Good video

[@kevinnequest8720]

Patiently waiting for a new video. Hope all is good brother. SKOL

[@pentecost66]

Great job !

[@henrikjonsson3397]

a stiff peice of rubber that you could put between the cylinder and exhaust works great. Cheap to make and chep to buy from Husqvarna

[@darrellpeak2914]

Awesome vid, very informative!

[@chainsawredeemer85]

Not supposed to swear anymore.... love it it isn't easy but iAPPRECIATR IT can you recommend a good compression tester. I can't find one for 2 cycle that works well

[@MrLtr450king]

Wishing you still were taking customers I’ve been wanting a ported 462 but I don’t trust a lot of people

[@schnittteisen]

Great Video. I just checked my 560 for air leak and it is leaking right between the bearing and crankshaft. How can i seal it?

[@johnscustomsaws]

I always hate to say anything without seeing it... comes with experience shooting myself in the foot trying to help 🤦‍♂️😂 but sure sounds like a crankcase/crank/oil seal (has different names)... but depending on your experience level they can be pretty simple or really involved... f you are talking about the husky 560 that's a clam shell I'm thinking... those can be a pain depending on your mechanical experience but not crazy difficult by any means... we sold the $hit out of those 560 Ranchers where I worked lol

[@schnittteisen]

@@johnscustomsaws Thank you for your answer. Yeah, without seeing... It is a husky 560. They are very popular saws here in GErmany as well. I had already replaced the bearing and seal, but it is leaking between bearing and crankshaft on the ignition side. I´ll try with a new bearing...

[@hertugen.online]

sounds more as if you have an under dimension crank shaft. The only way I can think you got a leak there.

[@cajun3197]

I just run with an air leak so it’s like having a bigger carb. That’s my secret to making em run 🤙🏽😂

[@mrxlh]

After hearing about pressure/vac testing from several saw builders, I bought one. I’ll never work on another 2 stroke without performing a pressure/vac test.

[@johnscustomsaws]

Smart man... I could talk war stories all day about guys screwing themselves (me included lol)... so many guys burn up a saw and do a top end rebuild just to burn it up again... I need to grab another kit now since mine has seen better days and I am missing the fluid resivoer and the handy attachments anyway so time to hit ebay lol

[@Witschor]

When it holds pressure and not vacuum, check the Crankseals ! Had a lot of them hardened out and made Problems. Great Video John, you got an Email from me!

[@philliphall5198]

Buy from oem and get fresh seals. Is my thinking 🤔

[@boyfowler6078]

Great video. Quite helpful content👍🏻

[@Trolldaddy5]

Interesting, you said you've never seen one fail vacuum that passed pressure. I have a husqvarna 372 right now that holds pressure but won't even build vacuum. I checked all my plugs and tools. How do you find where the leak is since vacuum doesn't blow bubbles out?

[@danielpospisil1192]

The ideal testing should be at the working temperature of the engine :) I can only think of the possibility of taking the saw with the pump to the sauna!

[@hertugen.online]

I used the water bucket for several years, an easy way to check for multiple air leaks. Especially on Husqvarna's 5xx series model, the bucket is brilliant.

[@dale1825]

where does the piston need to be when testing....top dead or all the way bottom?

[@foldingchaise8387]

GREAT Video, Thanks !!!!

[@justinweaver8787]

Great tool sir love it

[@yakbranson]

I got no sound for this video on my phone all others I do but on my tv I have sound for this video 🤔

[@johnscustomsaws]

What... that sucks... I was getting screwed by the "system" because I was using the same videos on both my channels so YT was copyright striking me for using my own videos 🤦‍♂️ but I got it sorted I thought... its a pretty informative video hope it works for you

[@RichFife]

Where the hell is John? Been waiting for an update... lol

[@RichFife]

Fawking Love it man! Thank You.

[@rc-daily]

Decomp on my 036 has leaked for quite some time...

[@justinp9515]

John, speaking of case pressures, I have a modified dolmar 7900, Ive retuned it multiple times and even put a new carb on it but when it’s hot and you go to restart it it floods out immediately, do you have any suggestions?

[@VintageEngineRepairs]

That isn’t 8 psi you’re pulling on vacuum, it’s actually 4psi. The mityvac reads inHg on vacuum NOT psi. There are 2 inHg to 1 psi so you need to be pulling 15-20 inHg on vacuum for 7-10 psi.

[@philliphall5198]

Yep your correct and remember that the higher the land makes big difference what it will pull down to

[@jimmyguerro234]

Are you available at this time

[@ryangerbers7419]

Do you have a website or how can I buy a custom saw or even buy a shirt or?

[@dennisthemenace57]

It is not 8 or 9 lbs of vacuum, you are reading 8 or 9 INCHES of mercury, a much different thing and scale. The equivalent of 7 lbs of pressure (1/2 a bar) is approx 14. 9 inches on that gauge you have. A perfect (unobtainable) vacuum is 30 inches. I agree with you on the importance of pressure, vac testing

[@darrylpilgreen8486]

Hay man can u port my 500i for me please I work in the redwood and would love for my saw to be a little more Rowdy

[@quentindavis6]

Good job

[@Chuckrussell75]

John, where the hell'd ya go dude? I haven't watched saw videos in quite awhile, so it hasn't just been your's. Well, I hope everything's okay!

[@dirtynerve22]

Hey John sent you a saw about a year ago , haven’t heard from ya send me a message bud?

[@jerseyjoshua4818]

BTW.... I took that bet, you just couldn't here me.

[@SOHN32]

Hi Bella.

[@SOHN32]

We couldn't see air bubbles. Someone fat head was in the way. Well give you a pass this time. Bubbles
