Just what I was looking for. This Honda clone engine is on a pressure washer and the recoil ripped out of my hands and back fired, so I knew it had to be the valves. I've been doing valves on tractors and mowers but never a pressure washer so knowing now that I have to find TDC with this particular engine. Thanks again
Hi FixitSam, thank you so much for posting this video. I have a Black Max 3650 generator with the Chinese version of the GX200. When I first got the machine several years ago it started fine but approximately two years ago (out of the blue) it wouldn't start. Of course it was really cold out so I preheated the cylinder with a torch and it started right up. I never dreamed that an engine with as few hours on it would need a valve lash adjustment so I looked for other reasons for the problem. After I couldn't find any other reason for the refusal to start unless hot, I popped the valve cover off and eureka!!! The exhaust valve had no lash at all. I adjusted the valves per your video and the engine started with one pull on the cord. Thanks again for posting this video.
Be careful if you over tighten the valve clearance on the feeler gage you can ruin the accuracy of the gage, as it gets deformed Always remove the feeler gage before tightening the lock nut, afterwhich recheck the clearance Do not crush the feeler gage. The gage may flatten and become dished then the accuracy is ruined.
Great vídeo my LoncinG200F ( a clone of the Honda GX200) mounted in a law mower started to back-fire and the motor seems to loosed power and sounds funny ... after 40/50 hours of work...the valves clearance have never been adjusted I believe it´s one of possible causes tomorow i´m going to try to adjust it one question: I know how to find the TDC in my 4 cylinder car motor..I have a clock comparator that screws on the spark plug thread in cylinder number one...I beleive that is the same in that case has it has o just one cylinder ..i´m right ? thanks....
Much easier way, turn the flywheel(engine) until one valve is fully down for example turn it untill the exhaust valve is down then adjust the intake valve, and vice versa
Does anyone know the lash adjustment measurement number for a car feeler gauge oppose to the numbers on small engine feeler gauge don’t want to mess it up and seems as if I have different units of measurement
The feeler guage usually will have both standard and metric thickness values on each blade. .008( 8 thousands) is a standard value and on the same blade the metric value of .20mm will be listed. There is no difference in car or small engine. Just the thickness of each blade. You will need to know which value (i.e thickness) you need for each valve setting. Hope this helps.
Didn't learn anything. You probably assume that I know what is top dead center or compression stroke. Makes me wonder if the video is for those who already knows what to do. You have left me with more questions than answers.
This video is useless because it is missing steps. You can't vocally tell someone to do something that they've never done without showing them first. You need to show how to get to TDC.
@@petecatch You're comment is an oxymoron seeing as it's a "How to" video. Stfu. You people are damn near retarded nowadays. You're wrong, deal with it by yourself.

Perfect video. It has all the information needed without being overly long, or technical. excellent work.

Thank you , had checked other long complicated videos and none worked your video is fast and simple engine is now running great :)

Best video ever

Perfect, thanks!
Hi what are the millimeters to use for the adjustment of the intake and exhaust valves? Thanks
. 15, . 20 he mentioned it.
.15mm .2mm
good job bro
U should have shown how to determine TDC Top Dead Center.
Using both the screwdriver method
And the
Finger over the spark plug hole method.

Thank you
Why or when do we have to adjust the valves??
After replacing head gasket, or if running poorly or sounding tappy!
just tearing into one of those engine,s tonight,,, thank,s for the info ,,,
I have the same engine for my garden When I open the air inlet more than halfway through, it turns off for no reason
Probably a fuel issue
Hi man, great video, do you have the service manual for this type of engine ? if yes are you willing to share it with me ?
I think you said eight mil for the exhaust that’s millimetres no you meant to say 8000 of an inch
Would the valves cause the engine to refuse to start, and possibly backfire? Just replaced the carb, the engine has been sitting for like 15 years...
Does it have good compression. Backfire could be a timing issue, check the flywheel key
@@FixitSam I've not that far into it, and I don't have a compression tester
Have that 7 year old girl with downs, down the street have a look at it.
Where's the audio can't he whats being said
Tapped fitting ka video Hindi me plese

Google it
Probably shouldn't be doing engine maintenance if you don't know these terms lmao

The video is far from useless, anyone attempting to check the valve clearances should already know how to get to TDC
