WOW, what a saw!
Remember the FR4618 McCulloch I asked about earlier this week? I was given the saw not running, but I got it to run, poorly at best.
Well, I got the new Intake boot ordered, but Im impatient...I went and got a tube of JB Quik Weld, and a pack of Epoxy stuff...
I cleaned the boot up, and dried it. Mixed up some clear Epoxy, applied it all around the boot, ripped portions and non-ripped portions. Let it set for 4 hours, then I applied JB Quickweld over that, and let it set for a few hours. It hardened well, but still maintained the boots flexible nature.
I took it out, and picked up the box filled with the disassembled engine, put it all back together, and about an hour later...IT LIVED!!! !!! !!!
Cranked on the 2nd pull, and idled right down. I put the mystery hose on the mystery rear engine hose port, and the saw wouldnt rev over 3-4K. It would rev quickly, then flood out, and stop revving.
I pinched off the hose, and it revved endlessly So as best I can tell, it is a Rev-Limiter. So I Leaned the mixture out until I got a top-no load RPM of about 11K.
Seeing as the bar oiler hose is still missing, I coated the chain in Shindaiwa Chain oil, and put it on. Went out to a Log.
The log of choice is about 3 months removed from its tree. IT was Oak, still quite Green. Eh, about 17-18" across. I revved it up and dug in, and it hummed through it like it was an old dead peice of rotten Maple.
The saw maintains a solid 9-10K top speed under Heavy load, with me bearing down on the saw. If I pull it out of the wood and freerev, it tachs up to about 11K and it starts dumping fuel into the intake, put it back in the log and it settles down, torque is immediate.
I dont care what anyone says, McCulloch made a darn fine saw in the MAC 4600!
And seeing as the factory crosshatch is still visible in the cyl. it has a long life ahead
