The Mac 3818 is the first saw I bought long ago when they were still in production and in some ways it's a pretty amazing saw. I kept one fueled for several years and found in that it starts and runs on stale gas and cuts fir reasonably well for a pico chained saw. To me its a perfect truck saw, not valuable enough that anyone would go through much effort/risk to steal it, but can still get the job done when called upon.Oh man...i have a 3818 that i garbage picked off the side of the road that i want to get running. Has spark and 150psi compression. It's leaking bar oil all over the place, i was told the oil line breaks. Are they really a POS to work on??
