Family friend wanted me to freshen this up a bit. Just add a little pop. Figure he has between 30-40 cord on it over the last 2 years. I found the saw for him 2 years ago, to replace his homelite c5. Needless to say he absolutely loves this thing. I let him run my old ported 371, and it was all over lol. First time ever messing with a strato saw. Lots going on under the hood. Well that ain't good, and wasn't like that when I picked it up for him. Can't believe it didn't wreck anything. Must have went straight out the exhaust. Not a mark in the jug other than some carbon marks. Anyone have experience with aftermarket 570,575,576 pistons. OEM are right round 100$ Numbers on this saw are 73 intake 101 exhaust and 109 transfers. .044 squish. And .017 base gasket. My plan is to take .010 off the base, set squish back to .018-.020 Widen ex a bit and raise it to 100 Leave the transfers where they land. Want to stretch the blowdown, hoping for 12-13. Just spend some time matching the boot to strato ports, and case to transfers. Nothing too radical here. Open up the muffler a bit, and should be good to go.
Good info, i had thought that the 575 was non strato and 576 was strato. I guess its like mom says u learn summthin new everyday.
Cut .006 off to set the squish,. Cleaned the carbon off, and final squish ended up at .021 Roughed up the intake, widening the ex just a bit. Took it back up to 101. Numbers ended up IN 75, EX 101, TR 116 .021 squish. It lives.. Put a aftermarket unlimited coil on, think it is too far advanced, sounds a little off. Gonna put the blue 13,600 back on
You haven't lived until you make popcorn on the stove top with coconut or peanut oil. Yummo! Joe the saw does sound like it's a little advanced otherwise sounds pretty snappy. Nice work!
Did it with the stock coil, it doesn't like being rich at all. Set at 13,300 just under the limiter. Just a dog in the cut. Leaned it out round 13,800 with the China coil, cut/souned great. For 1 cookie lol, coil junked out. Need to find a better unlimited coil or a 346 coil. Other than that it seems to run pretty well.
While I don't like those saws as much as a 372, they really aren't a bad saw, contrary to the reviews you see online. I've rebuilt a few. They run strong and are smooth.
Definitely a nice smooth saw. Really wish I was given free reign with it, but sadly I had to keep it mellow. Get the comp up in the 210 range add some more time area, unlimited coil, yeh one heck of a runner for sure.
