Cleaned carb mower runs fine, however priming circuit does not work always. Cleaned prime hole on left side with carb cleaner, replaced gasket on carb back plate and checked primer bulb and cleaned screen that pushes primer air into carb. What else should I do to improve starting easy? Now will start after several plunges of primer 4-5 pulls of rope then more priming and 3 or so more rope pulls. All fuel is fresh with stabilizer. Thanks for any ideas and help.
 
If this is the model with the primer in the end of the air cleaner case, and uses a flat air filter, not a foam, you are probably losing your primer pulse at the gasket between the air cleaner and the carburetor. Check for a crack in the air cleaner near the pulse hole and also a crack around the closest screw hole. Sometimes, doubling the gasket will help.
