Would you try to run this ?

First, check to make sure that ring ends aren't dropping into any ports. Then check for free-porting. If those are good, go ahead and check port timing. That's literally one of the worst hack jobs I've ever seen. How someone could do something like that is beyond me.

I'm certain u could grab anybody off the street and they could do better. They had to have wanted it to b a mess.

Looks like something I might have done as a teenager... I remember those days, but those memories are fading lol!

I've still got the first chainsaw cylinder I ported and it's not to bad. Shape wasn't great but its symmetrical and smooth.

Any clue where that cylinder came from??? I think i have seen it before.. Could be my eyes playing tricks on me..

Why not smoothe it out, bevel ports, and try it? What is there to loose?

 

[blsnelling]

Make sure it's useable before putting any more work into it.

May be a couple of weeks. Need to get the bearings in from Hong Kong and I am going to Hatteras fishing next week and maybe deer hunting the week after that. But, I will check it out and post it .

The ring retainer has been ground out of the intake.
It's junk.
If it runs, it won't be for long

Are you sure that model ever had one ? I guess you are talking about the bridge or whatever in the center of the port that you see on older saws.

I'm really sorry I ruined that cylinder for you!......My mum has now hidden my rasp !

Wow I didn't know the roto zip could do such a nice job lol.

Don't laugh. We once had a guy port a saw with a wood router!

Too bad I couldn't hold back. How did that turn ou . Did he use the router tooling or stones and burrs

I'm not 100% positive.

Heck man, I ported and polished a Dodge 360 when I was 14, it turned out great! I don't see any excuse for work like the OP posted.

 

[wde_1978]

Darn it, so it's NOT supposed to look like that?

Shucks , I'll have to redo my SD105 cylinder port job then, maybe weld some stuff back in...

This is my hack job, done with a regular electric drill and a tungsten-carbide burr, finish done with some ultra fine sand paper and my finger.
And no, I didn't touch the opening inside the cylinder as that is the only good jug I have for this saw (the "before" jug is a trashed one).

I took the sharp edges off the inside of the ports and other than seals and bearings put it back together as it was. It is free porting a little but the ports are so sloppy I don't really know how to measure it. I ran a tank of fuel through it this morning and it runs fine. I don't know if it is any better or worse than a stock saw but it seems to have as much power as other 026's I have had. I suppose I will sell it to one of my neighbors since that seems to come with a lifetime warranty anyway.
