The 4mix has decompression on the cam gear.If I spin it with a 1/4 impact will it be fast enough to check compression?
The trimmer bogs down when it hits heavy grass. I changed carbs, adjusted valves, changed cam gear,I think it may be carbon buildup on the valves or it is just worn out. It is 18 years old. It starts fine and runs fine but if you hit the string in the ground it will bog the engine down.Sometimes it will cut off when you let go of the throttle.
