Small Engine Repair Valve Lash Clearance Adjustment on Honda, Predator, or any Engine

With that loud of an engine knock it was a long shot to just reset the valve lash clearance. If you watch to the end you will see the engine knocking is coming from the connecting rod on the shaft. Since nobody reads this description I’ll probably get a lot of people saying they knew right off hand that it was the connecting rod. This video isn’t to all those small engine experts. Its for those fix it in your garage type that want to add something to their bag of tricks.
Keep in mind, do this when the engine is cold.
This system works for all small engines. Doesn’t matter if you have a Honda, Briggs, Tecumseh, or even everyone’s favorite the Harbor Freight Predator 212. If you remove the pull cord assembly and it doesn’t have a triangle to designate TDC, top dead center (or both valves fully closed), you can pull the spark plug and put a screwdriver in and see when the piston is at TDC, then continue.

Here are some other links to more small engine repair videos:

Easiest way to adjust the clearance is by turning the crank until one valve is all the way open/down, then adjust the oposite valve.
In this example the piston is actually almost ay BDC each time, and no need to be on the correct TDC stroke, and also no chance you are accidentally adjusting during the TDC valve overlap position instead of TDC compression.
This method also avoids accidentally adjusting the exhaust valve while the decompression cam is acting on the exhaust valve lifter/tappet👍
Also, try to leave the feeler gauge between the lash gap while tightening the lock nut, if the feeler gauge slips out you're gap is too loose, if it's hard to remove you're gap is too tight.
If it's just right, the feeler gauge will be held in place but won't be too difficult to remove ince the lock nut is tightened.
Minor point, the area that got hot shown in the video was the crankshaft journal, not the conrod, but most likely both will be worn, moreso the conrod being it's aluminium.

Wow, I just fixed my generation with this, thanks

I have a wpx3200 pressure washer and can’t get it to start. I did valve adjustment and found intake rocker arm was very loose and could rotate it without even loosening nut and exhaust valve was too tight. Did the adjustment and now it feels better when pulling cord but still won’t start. Cleaned carb, fresh gas, new spark plug and gets spark, air filter is good, with fresh gas. Any other suggestions? Doesn’t start with starter fluid either. I do get some pops when attempting to start like some backfire.

What would cause the jam nut to tighten causing exhaust valve to tighten after running just once or even a few runs? Thanks

[Prariedog]

Would you know the feeler guage needed for 210 cc powerease BE water transfer pump. It's a 7 horse engine . Thanks

[DewoncheBrown-bpnc]

Thank you for inviting us to dinner. I didn't realize this! Food 4 thought.

Something to be aware of... all threads have back lash.. (slop) as you found out.
Set your lock nut on top to be in slight firm contact with your bottom nut when you feeler gauge.
Both those male threads to nuts fight each other on tightening and yes male threads DO flex as well....

[larrywilbanks]

How do know which is intake & exhaust if they are stacked on top of each other not side by side

[doughball]

Do you know valve settings for Generac power washer model 65950 with a 196cc engine.

[kameronday]

Thank you for this video, you helped me fix my thatcher🙌🏻

[stevenkinnison]

I have never used a set of feeler gauges on these. I just tighten them until they barely wiggle and have had zero issues out of any of them.

My brothers mini bike did the same thing we tried to adjust the valves it ended up being the piston arm the two bolts backed out we took the side case off and tighten them up and no more ticking

[alstonasby]

So my zero turn which has a predator 700 motor on it had been hard to start and then backfiring a lot recently and I pressure washed it one day and now it won’t start and I took the valve cover off and the cam rockers or valve rockers are super loose and it would run for like 10 seconds and then cut off and I’m not sure what my problem is with the right cylinder which is my problem having 40 psi of compression in my left cylinder having 160 psi of compression

[strxrippin]

I adjusted my valves which was needed as I saw they were over tightened. Now that the valves fully seal up the engine is extremely hard to turn. As if the compression release isn't working. I'm stumped. It ran fine before so idk what's going on

[mikeinpenna]

I had to replace the push rod guide plate on my Gentron generator, looks like a Honda knock off. I only found a cap on the exhaust valve spring. Is there suppose to be a cap on the intake side also?

[Benito-guww]

My Honda clone engine manual says 0.10-0.15 for intake valve clearance and 0.15-0.20 on the exhaust

[tonyjackson]

Not sure if you mentioned... I FF'ed through video, but spec is also within +/-.02mm. In inches these Hondas are .006 intake, .008 exhaust, +/-.001.

[MoroniGivens-jqmi]

so vavles loosen distance or get tighter age. Garage generator videos says tighten up age

[koowonjosiah]

Wow what a nice videos, I'm so happy to see such a unique videos from you! I am from Liberia my name is Josiah, can you make a video for me? how to change a piston rings, I have Little little problems on how to set a ring on a piston, I have my own generators at home 2.5kv, I really need more updates from you and appreciate

[alanhowarth]

Simple, informative video. Should be more like it. Thanks.
