What are the chances of the float needing to be adjusted a little bit?? Tried carb cleaning around all the areas where there's a possibility of a gasket being broken or blown, no issues there. If the mower has a load on it it runs down on power, but smoothly, not like it's a misfire or anything like that. It runs down like its running out of fuel. As soon as you ease up and either slow the mower down or shut down the blades, the RPM's pick right back up again. If thats the case then it should be a simple adjustment. Just trying to get some ideas.
