Ok, so I wasn't sure if I was gonna have time to get this saw done in time. But lo and behold I got to it in the eleventh hour. Not sure if I will get it together and runing before tomorrow (Saturday) but in case I do, I better make a thread.

I had originally intended using the farmertec jug but opted instead for the cross. After some brainstorming I opted for a 288 piston. So MMWS cylinder and 288 Piston.

Jug looked ok. Exhaust roof was flattish.


Band looked good. Transfers were large and needed a little flash cleaned up but overall I was happy and it will work.


The reason I went with the 288 piston was mainly for fingers and it allows me to really widen the exhaust. Pictures to follow.

First up we gotta degree this sucker.


Not So Fast!!!!!!!

Clearance issues presented themselves as well as some excessive lateral movement between the bosses. Let's fix both these issues shall we?
Clearanced the skirts



Made a couple spacers to allow the con rod to locate.

Back to the timing. With a gasket, squish was way too tight. .065 .

My degree wheel tells me I'm at 100/116/80. With squish so high I opt for a base cut only. I'll remove .048


This put me at 102/120/83. If I had started this build sooner I would have epoxied the intake but I'll run it as is for now. I can live with 83.

I wanted my fingers to open 2-4 degrees ahead of my mains.


Widened the exhaust port and beveled the roof and the floor. I'm ok with the flat-ish roof with a good bevel. Didn't touch the intake except to smooth the edges.

Nice Brett!
How was the plating cutting those fingers in?
Compared to an oem jug?

288 piston FTW!

But will it love you long time?

Plating is ultra thin. Nothing like cutting fingers on an OEM jug. Much easier, quicker. But I'm worried it's gonna peel.

That's what i was wondering ...

It's going into the logging woods. Not sure how long it will last l. But I'm curious myself to find out. This guy takes care of his saws so neglect won't be the issue.

Is this thing still alive and well. [emoji6]

This thing is alive and well. Talked to the logger today and he's only cut with it one day. It's been wet lately here. But he said it certainly had power. I should've taken some video beforehand. It's all AM except for the piston and clutch drum. If the worm gear burns up I'll get it back for a bit and get video for sure.

Right on. Glad it's doing well. With all the trouble with bottom ends in these things I figured yours would be a good test since it's eith a logger. A guy is interested in buying mine and 8m worried it'll grenade now. He's not a logger so it's not gonna see a ton of use.
