How to Install a Locked Chainsaw Sprocket Plate
Chances are that you'll need to know how to reinstall a locked sprocket plate on your chainsaw if you perform your own repairs. This article explains how to reverse this common repair mistake.
I replaced the fuel line but do not know whic line the fuel pick-up assembly goes to. Is it the large line or the small line. When running it seems to run out of fuel, starts to die.
My 1800 will not oil. I also have a micro 25 which seems very similar. I have cleaned the oil reservoir and replaced the tube between the oiler and oiler window at the bar. I'm not sure of the theory of operation. How does the oiler work? Does something pressurize the oil reservoir causing the oil to enter the oiler and go up thru the tube to the bar? I saw something on the diagram about a check valve near the clutch; is that relevant?
I've got an 1800 and I can get it started no problem but it shuts down after a few seconds after I take the choke off. Could this be a carburetor issue? Also, is there an air filter on this model? I'll be darned if I can find one.
It could one of several things. All saws need to breathe and get fuel. The air filter is located under the housing where the choke lever is located near the front of the saw. Second check; clean or replace the fuel filter located in the fuel tank. Next check to see that the fuel cap is breathing. When fuel is used air must be able to replace it in the fuel tank otherwise a vacuum develops, working against the fuel pump.
It is also possible the fuel line is cracked, hardened or deformed or pinched. I have found fuel lines to be the culprit a lot of the time. I have seen valuable saws discarded for that reason alone. If the fuel line is over 2 years old, probably wouldn't hurt to replace it.
Ok if all that is good the carb may be a little gummed up . You may need to adjust the carb low speed jet. Look on the carb. there are 3 adjustment screws: one is idle the other are low and high speed respectively marked L and H. Rotating the screw counterclockwise will increase the fuel rate. Play it with and see if that helps. Always remember the starting position of the screw.
After the saw has been run a while a readjustment may be necessary. As it is used slight gum deposits sometimes clean themselves up. If none of these remedies works, the carb may need to be worked on. The best thing u can do for a 2 cycle engine is crank it and run it periodically. Good Luck!
