Today I fired up my 40 cc Craftsman 18" chainsaw that I got for $100 (it's new -- someone had bought this for his brother, who turned out to have one already). Worked great. This is the first time I've used a gas chainsaw since many years ago: Here are some questions: 1. To test the inertial chain brake, the manual says to hold it 13" above a stump and let the tip fall. For me the brake engages (clicks on) only if I hold it more like 20" above the stump. I'm assuming that it is working properly, yes? 2. Stupid question, but I assume that the choke should be pushed in as soon as the saw has been started and you start cutting. It doesn't say this explicitly in the manual, but the choke tends to pop in by itself as soon as you rev the engine, and you're hand tends to push it in when you grab the rear handle. Push it in? 3. After 10 minutes of use, I had a problem with it dying as soon as I applied the throttle. This problem went away, and I think it was caused by letting the saw idle for a long period (I had left it idling on the ground while I moved some logs -- I realize now that that wasn't a good idea). Agree? 4. For safety reasons, the manual recommends never leaving the saw idling while on the ground. I was cutting a bunch of smaller logs, and for each I'd make a cut, then move the log on the saw buck or get the next log. To do this, I was essentially making one cut, turning off the saw, putting it down, adjusting log, starting saw, making next cut. Apart from efficiency issues, is this kind of on/off stuff OK for the saw? 5. After working for 30-40 minutes I was done. I let the engine cool, then opened the fuel tank and poured the remaining gas/oil mixture into the gas can. I then started it up and ran it until it ran out of gas. Proper procedure? 6. I tightened up the chain, cleaned off the saw and put it away (will use it again in a few days). Anything else I should do? 7. The manual says, just before the chain tightening section, "Always unplug the spark plug before performing any maintenance. That involves removing a few screws and popping off the top. Do you do that?? I'm guessing the answer is "no." 9. It's OK to leave the bar oil tank full, yes? 10. If I have left over gas/oil mixture that I won't need for a while, I assume it's OK to pour it into the car's gas tank, yes? Thanks for your help!
