Kohler 6.5 engine needs help starting....

[Peavey]

I have a 4 year old log splitter with a Kohler SH265 engine.
I've had it since new and if I start it every week it fires right up, no problem.
However if I let it sit longer than a month or so, it won't pop/fire.
It's a recoil starter so after the 15th pull I get a little Po'ed....
So I've started removing the air cleaner and spraying a 1/4 ounce of gas into the carb then it fires right up and runs for hours, perfectly.
I have other small engines that sit as long or longer and don't act like this one,anyone have a solution/suggestion?
Edited to add, I only run fresh non ethanol gas.

The spraying 1/4 ounce gas bringing it to life has me puzzled... otherwise I'd say bad gas.

Maybe the carb is draining itself, and pulling it by itself doesn't bring enough suction. Your choke ok?

The pic's I could find, looks like a normal gravity feed fuel system, with a shut off valve.
When something won't run, go back to the basics.
Fuel, air, compression, spark.
Something is missing or in wrong proportion.

Since it will fire off with a snort of fuel, I am suspect the choke... or an empty float bowl.
Since it runs fine once started... Maybe there is just enough restriction on fuel flow that it takes time to refill the carburetor? Check the sediment bowl. Check the needle and seat.

It looks fine, it appears to close completely.

are you shutting the fuel supply off and running it until it shuts off after every use?
