Honda EU2000i valve check

[Ausfahrt]

My 2007 inverter generator has been getting hard to start lately although it runs fine. The carb was cleaned last year so that wasn't the problem. I have never checked the valve clearances so I figured it was past due. Checking and adjusting the valves is the easy part but getting all of the plastic off is another story.

Honda specs are .15mm for the intake valve and .20 for the exhaust and both of mine were way too tight.

It would often take ten pulls or more to cold start the engine but after the valve adjustment it starts within two pulls every time! I should have done this a few years ago but I feel better now about relying on this generator in the future.

check for free movement of the valves. they get gummed up and stick .

Good tip. Mine still starts okay but is seldom used.

Interesting valvetrain. I assume that's an OHC getup, the cam having the large sprocket on it, but how does it actuate the valves?

Good question. The EU2000i has the Honda GX100 commercial grade engine so you can look it up. Here's a pic that might help.

Thanks for posting that, I thought the stamped metal pieces were the rocker arms but wasn’t sure.
