Starts like normal..........runs normal until warmed up. Then bogs out and/or dies when throttle is applied. I can feather the throttle to get the her to run well..........but then when a load is placed on engine, she bogs out and dies. New plug, cleaned air filter. PoulanPro PPB100
The carburetor probably needs to have a kit installed. The diaphragms are probably stiff and need replaced. You can try and adjust the low and high on the carb to see if it helps. CCW will richen the fuel mixture and what you have is a lean condition.
If carb/fuel line repair doesn't fix it, pull muffler and look at piston, ring, intake wall. Pull plug and look at exhaust wall. Another possibility is some scoring or ring wear and lower compression when hot.
Put a little Sea-foam in tank , run it for a bit , might do the trick , if not ,go from there. It's surprising what a little Sea-foam will do
