A few things come to mind to me:
1. Hydraulic oil need to be replaced along with filter
2. Valves need adjustment
3. Carburetor needs to be disassembled and cleaned
I got into the habit a few years back to disassemble an place my carbs in an ultra sonic cleaner during service. This gets all the dirt out. Very rarely now do i have carb problems. The ultra sonic cleaner works on all small parts I clean spray nozzles and screens in it also.
