 Honda Gx270 Will not start Stumped

As Murf said the Honda engines have an oil sensor for low oil level. I think the oil level might be the culprit.

On my Honda engine based pressure washer I filled it to what I thought was the fill line, but actually was too high. I got the same symptom you describe very hard to pull starter cord indicating oil level too high.

I would pull the spark plug and clean it in gas if oil fouled, drain some of the oil out until you can pull the cord and it spins properly, then put the plug back in and let it sit for an hour or so and try to start it again.

Tom,

You have really hit so many areas on this...

If the engine ran 15 seconds several times before you did the valve adjustment, I sincerely doubt that the valves needed adjusting. I assume you found no broken springs or loose nuts when you pulled the valve cover. The adjustment you made is most likely the source of the hard pull because it is significantly off. Trying to run an engine with a bad valve adjustment can cause dire results.

Been down this road before, the problem is just one simple thing like a bad oil sensor or similar simple thing. But we are missing it and attacking every system on the engine.

Now since we have touched 6 different things we now have 6 factorial probabilities of things that could be an issue.

I had a an old Corvair that I rebuilt an engine on to no avail to cure oil blow by, so I feel your pain.

PS when you say fresh gas you mean gas you just bought this week right.
