They gave me a chainsaw of Chinese origin that doesn't work, and I'm trying to start it.
I started disarming it completely, I didn't see any lines in the cylinder and the piston/rings/crankshaft either look bad. I made the new joints, and bought the replacement of joints/membranes/diaphragms for the carburetor, which also disarms and cleanses it. I have put the new and checked spark plug that has a good spark. The engine seems to have good compression.
I have put it again, but there is no case, I can't start it. The only moment in which it starts is when I take a few drops of gasoline through the carburetor air entrance (where the air filter goes), there turns on for a few seconds and stops, when accelerating it does nothing (although releasing the accelerator stops faster). With or without a primer, I never listen to do explosion as if it does when I gasoline through the carburetor.
In this manual you can see the carburetor that is practically the same as I have (page 28, HDA carburetor).
I thought I was not getting naphtha to the carburetor, but when I take the measurement lid at the bottom, and press the input valve (it is a small needle with the spring), Gacolina comes out. And with the armed carburetor, if he breathes for the small hole in the lid (making the diaphragm move the valve, I see that carburetor gasoline dripped. I mean that the upper part of the carburetor is full of gasoline, it seems as if the diaphragm from below would not be driving, but the membrane and joint are new and the carburetor does not have covered ducts.
it goes down in a thousand different positions but there is no change.
