The tip to hold the inside nut before loosening the jam nut was worth the view. thanks. also people make the mistake of adjusting the valves on the wrong TDC stroke. You did mention TDC on the compression stroke which is correct. Thanks.
Ok question. I have a gx 690...looking at the motor...to my left i took off the cap that covers the valves and took off on my right side too. There is one that loose, alot of play but the other 3 are tight. What does that mean? What do i need to do to fix?
You can remove the spark plug to stop it building compression while you spin it over to do your testing. Then just watch the exhaust valve to check that it does the big dip on the exhaust stroke, and the little dip on the compression stroke, which is what makes it easier to pull start. My engine had this fault,and was scary to pull start. Would pull the rope back out of your hand with what felt like the strength of 5 horses. Resetting the valve clearances cured it, although getting into the crankcase, removing the camshaft and cleaning / checking the compression release mechanism is actually pretty easy if resetting the valve clearances doesn’t work.
valves are adjusted right how do i know if the pressure release on start up is working i don't see the exhaust valve move that little bit. any other way to check that?
on my bcs with gx390...I have hunting/surging. I've ruled out air/carb issues for sure. Would valve adj possibly be my next thing to check? would that cause hunting/surging?
Good vid. However, since the edge of the valve/rocker compartment is sharp edges and the jam & adjusting nuts are often almost seized together, it is a good idea to use a socket & ratchet to loosen the jam nut to place your hand further away from the compartment so that u can't accidentally bang & slice open your hand as can occur when using a 10mm wrench.
I liked that your video touched on my current issue. I have worn out seven gx200 clones in the past 5 years (2 tillers and 4 generators plus a new engine). My major problem has been excessive wear of the exhaust valve seats and the pushrod guides My newest purchase is a 3k generator. In service only 3 months, and already problems. I have read about others with my problem, but still looking for a solution. I cannot get the compression release to work as it is supposed to unless I have zero clearance on the exhaust valve adjustment. I'm hesitant to do a tear-down just yet to investigate (void warranty). I certainly could use some feedback.
THE BEST DEMONSTRATION I HAVE SEEN ON ADJUSTING THE VALVES ON THE HONDA GX SERIES. GREAT JOB!

Thanks for pointing out that tightening the 10mm jam nut tends to screw up your carefully set gap
Is that why a backfire is out the exhaust
Wow, verry great explanation. Thank you very much for that

Your governor maybe out of adjustment and/ or your maybe your carburetor main jet has a tiny amount of crud in it.
Quality video as always.

hey would the clearances be the same on my honda gx-340 11 hp its on a excell pressure washer
Outstanding presentation which I followed with good results. One question, there's almost no oil on the rockers, is that OK??
Great job. I really appreciate it.

This video expllains it perfectly
Well done ! Thank-you.
Nice job and you made it easy
I took the liftrods right out, what do i do now?
Put em back in, use locktight. Keep the push rods in the same hole they came out of if you can.
What do you do if the stud got loose? Locktight?
Just get some locknuts
6/1000 is actually 0.15 mm not 1.5
Why are the tires on your tiller on the wrong sides?
Loved you on Dirty Jobs
Six thousands is only for intake valve,for exhaust is eight thounsands.
The valve clearance is 0.13-0.17 mm (0.0051-0.0067 in) for intake valves and 0.18-0.22 mm (0.0071-0.0087 in) for exhaust valves.
@@walkertongdee 0.15 mm intake and 0.20 exhaust.
Exhaust is on the Left Intake is on the Right.
@@walkertongdee that is . 006 and .008 thou.
1 and half mm no wonder its loose🤣🤣🤣
Good video I just came here to find the valve adjustment spec.
He used the same one for both, wrong. •15 inlet •20 exhaust.
6:50 1.5mm, isn't that 60thou?!🤔
Thank you
Your specs are wrong .006 Intake .008 Exhaust ...
Would somebody get that darn phone!!!😁
Gracias
What is one and a half millimeters? WTF?
Nice Video, but cleaning hoses is not your strengt,huh?😂
Good video but shut the damn phone off!
6 thou is ZERO .15 mm, not 1.5mm. Plus use 8 thou for the exhaust, otherwise very good. Thanks.
You need to be on the intake stroke.
Then get the piston top...
I recommend watching a different video.
Exactly....when he said 1.5 mm I went what the hell are you talking about...
Turn phone ringer off
Next time turn the phone ringer off
Your specs are wrong .006 Intake .008 Exhaust...!
