My apologies to all that a piece of dirt on my screen made “seals” look like “seats”. @StarTech, you are full of yourself and very unprofessional. Your last post proved that.

Valve seats are not a service part offered from Kawasaki and are not replaceable. Though, check with StarTech, I’m sure he can make some from an old piece of pipe.

@StarTech you are stuck in the 1970’s. Drilling out jets is to compensate for you not knowing how to properly diagnose and repair the issue.

There is no adjustment for that. Either there is a welch plug missing, as referenced in the above picture as 92066 or there is junk in the fuel system or a slight air leak somewhere.

The compression release mechanism is part of the camshaft assembly. Not likely the cause for low compression. Common causes of low compression are stuck valves or worn rings/cylinders from dirt ingestion.

If BS is what I think it is, how professional. These screws are idle port mixture screws, both flow fuel at both low and high idle. They are covered by a welch plug for a reason as they are set by the carburetor manufacturer and are not intended for "tuning". The only low speed adjustment is for...

There is no low speed adjustment. You can adjust the carbureted low idle. And the governed low idle. EPA does not allow adjustable jets.

Likely, if it were something mechanical it wouldn’t take 10 minutes for it to begin to do it. If choke helps, this is because the choke is enrichment the air/fuel mixture enough to keep it running. I believe it might be an air leak that is revealing itself once the engine gets to operating temp...

If it’s not fuel or fuel flow related, then likely an air leak. Try spraying carb cleaner around the intake gaskets, manifold and insulator. Likely you either have a lot of money or are buying aftermarket carburetors. The original is likely fine unless it is corroded, broke or missing a part...

As Rivets suggested or there is a fuel restriction somewhere. Will it start right back up and run good again for a period of time?

15 hp means nothing. I can think of at least three Kawasaki 15 hp models.

What engine model?
