ULPower 500hr valve check on the Super701

This is more of an informative/instructional video showing the process of checking/adjusting valve clearances on the ULPower 350iS during the 500hr maintenance on the Super701. It is a very simple procedure and allows you to get an easy glimpse of the general health inside your engine.
It is a bit longer than my usual videos and I do a lot of talking, but I hope it is easy to understand, follow, and enjoy.
Thanks to David Hart for the cover shot for this video.

The overlap method is how I adjusted at least a thousand VW and Porsche engines when I had a shop for 15 years. First time I have ever seen it demonstrated. It makes it easy to visualize the cam lobes that affect two cylinders (when overlap the opposite side of the cams are TDC and to be adjusted)

great job showing how to wrench on your motor. I"m a two stroke guy but have nothing against either, I think the problem comes down to not understanding how to work on your own engine. I have almost 80 hours on a single cylinder two stroke hirth and I just replaced the fuel lines out of caution. I feel as confident in my little two stroke as a lycoming or contintential because I learned how to work on my motor just like a ap would.

Great build; great explanation of how simple the valve adjustment can be.

Still waiting on part 3 of your new prop.

Enjoying your videos John, thanks for sharing.

Well done on explaining “just a little drag” I’ve noticed some people jam the gauge in to make it fit... 😌

[@timrobinson6404]

Thank You for sharing!

Excellent video, Jon - I appreciate the detailed explanation! Will you be attending the Zenith Homecoming/Fall Fly-In in Mexico, MO this September?

[@markrutlidge5427]

I agree that the nord lock washers are great, however I have heard of one person who put them on wrong and won't touch them again. Would be nice if you showed them and explained how they work.

Hey John... what are the terms of your warranty concerning which routine maintenance and adjustments you are permitted to perform? How's the new prop working out? Thanks for the update and info! Blue Skies!

[@stevegromak887]

Do you check the torque on your head bolts? The manual says they are to be checked, I believe every 200 hours....at least in does on my 520iS.

[@jimharter3131]

John. Just wondering whether you use 100LL or mogas?

[@foesfly3047]

Do you run unleaded auto gas to avoid the lead build up they say happens when using AvGas in UL Power engines?

[@foesfly3047]

Is this to be done with the engine Cold?

[@MACE1-1]

Jon - Whats that piece coming off your oil filter block connected to the oil cooler line? check valve? If so why do you have it installed...? Just curious...
