Have an old pioneer p38 chainsaw, belongs to the old man. hasn't been started for a few years. replaced fuel gave it a clean thats all, wont go.
You need to disassemble the carburetor and check the diaphragm. You need to blow nozzle of carburetor. If the fuel was left in him, now it has remaining traces of oil. You can try to start with a small pump to inject fuel directly into the intake of the air into the carburetor. Of course, the spark has to be here to start. Older chainsaws had a switch and a capacitor, which is very difficult to adjust. Newer chainsaws have electronic ignition, so it is easier for test. Most of carburator has three buttons to adjust. L (low), H (high) for fuel injection at low and high speeds. There is also a minimum (the chain must be stationary if it is well tuned). The chainsaw is set at low rpm throttle with screws ( L ), and its vivacity is set at high speeds ( H screw ). In the beginning is good put both to set at 1.5 turns from full closure. And then, if the chainsaw starts, you can adjust a carburetor work. Careful with adjusting with H due to high speed. Good luck!
