Well, my search for a builder is over... HOORAY 288!

[Onan18]

When I can keep a rope in it, it's a running sob for sure.

Step One: Buy better rope.

Lol got it covered this time I think

Doesn't hurt to get lucky either, right Mike

Right lol

I do wonder if that cylinder would sing a bit more if I matched the muffler to the outlet and added a second port or at least enlarged the existing one. The exhaust outlet on the cylinder turned out a fair bit larger than the muffler opening once I was finished grinding it.

As we discussed, I think that Saw is in desperate need of a MM to compliment the exhaust port changes.

 

[rattler]

Yes sir I would port match the muff and a extra deflector th her

What is all involved to convert the 394 carb to run on a 288?.........Might need to do one for my 288 once it hits my bench.

Aldawayz port match da moofler to da exhaust port...

Well, I was going to put off porting the cylinder im using for myself for awhile. That's why I didn't open it up yet.

 

[huskyboy]

The second saw in your videos seemed to hold more rpm in the wood.

 

[huskyboy]

Did you get chance to tach them in the wood to see what there pulling?

 

[dustinwilt68]

Lol got it covered this time I think

That's what happens when you try Stihl rope on a husky, just can't take all the power.LMAO, sorry buddy couldn't resist.

The second saw in your videos seemed to hold more rpm in the wood.

I tend to agree with you but Josh ran both saws and said that the first (which is the KS cylinder I ported) felt stronger to him.

Sorry but we didn't tach them in the cut. It had just finished snowing and I knew I was going to get called back to work, which I did just as we finished the vids we got. I can say that the first saw tuned to 13.2k and still was 4-stroking.

I'm sure that matching that muffler to the exhaust outlet will help, but by how much? I know one part of the porting job that left me feeling dissatisfied due to my limitations with the tools I have is the transfers, as I have mentioned here earlier. This KS cylinder compared next to the Mahle is quite different, particularly in that the transfers are much smaller. Now I did gain upper transfer window area when I raised and widened them, but the lowers and mids is where I think they still need a fair bit of work, and I'm just not able to do that yet...at least not on a cylinder that doesn't belong to me. What I think I did accomplish was to make this early KS cylinder with what I feel is an inferior port layout compared to the Mahle run at least as strong as the Mahle. I hope this makes Dale happy and as I have told him privately, I would gladly take the cylinder back to work those transfers more once we get our proper grinding tools. I think that is the bulk of why I seem to have left something on the table with this cylinder.

All said and done, it's certainly no dog.. but I'm not feeling the "Wow" factor just yet. I think the basic timing numbers are good, but I need to work those transfers thoroughly and mod that muffler to get it really breathing better

Oh and....HOORAY 288!!!!!!! That frozen sugar maple is some nasty stuff and they both chewed through it like champs.

^^^THIS^^^

Sugar maple is some TOUGH wood and will work the snot out of any saw.

 

[RIDE-RED 350r]

Another thought as I sit here pondering... I need to advance the timing as suggested by Danimal via PM.

Been chatting with Dale via text, he tells me he is not in a hurry so I can do some more experimentation. I've decided to match and mod the muffler as well as advance the ignition timing.

Stay tuned, I think these additional changes may yield some descent results. That muffler I got SOUNDS restrictive compared to Josh's. I wonder though, enlarge the existing, or add a second port? What do you guys think?

 

[Mkinslow]

I’d enlarge the existing outlet Like this one

 

[RIDE-RED 350r]

That right there isn't a bad idea.

I’m no saw porter, just a dude that likes to run saws lol, but I’ve heard and read so many times “power is made/found in the transfers”. So your probably on the right track. I think timing advance .20 would gain a bit and match muffler to cylinder.

 

[jakethesnake]

I kinda dig the dual ports. I think it’ll get ya the same results.
