One fast little 238SE!!!

[ericjeeper]

Square ground test?

Hey Brad did you get time to grind up a fresh loop of Square to see what the difference in times will make? That will answer some of the new guys questions about how much faster square is than round ground..

 

[SawTroll]

This 238se was the first new chainsaw that I bought. Now I have some renewed interest in it. I have alot of testing to do. I want to find the right bar and chain comb for it. Hope this bar that SawTroll gave me works well on the 238





.

I believe it fits better on the 339xp by now, but may be very good on the "238" as well, with 8-pin and 23RSC or 20LP....

For those that don't know, that is a Norwegian made Husky .325NK bar, not a rebadged Oregon Microlite-Pro.

How long y'all reckon is it going to hold together at 17k RPM?

It would be interesting to see a ported 238se top end up against the 242 top end...

I have "heard" that they run even better than the P5000, if you put a P5000 engine in there (same size, but still different).......

I'm not sure that will work. I have some hard to understand service bullitin here, and my understanding is you need a 50 Special to do that swap. The case was changed when the Special was introduced.

I have a dark top 50 here as well as a 5000, just never felt the need to tear em down to see for sure.

Sounds a bit high to me as well, but it is "only" 1.5k more than speced for the 242xp.

Now ya got me wondering the same thing.... I have always had an eye out for a clean 50 thinking I'd put a 55 top end on it. Mainly just because you never see 50's. Never heard of a 5000 top end on one.

I'm almost certain that won't work.

I tried that bar on a few of my saws. The best test was on the Domar 5100. Had the 8 pin sprocket on it and it was one fast saw. Thats what gave me the idea for it on the 238.

Brad that's really fast work you've done. This is my best experence dealing with a builder yet! Last fall when member Stihl 041 was telling me about your attention to detail I never tought that you would be working on my saw.
Thanks!

"Yeah my 55 has open ports, I've heard some have closed, don't know for sure."

I have a 1998 model with closed transfers, and it is a very strong runner, and one of my favorite "little" saws.

I just bought a model 51, but haven't checked to see if it is open or closed? I'm thinking open because it doesn't run nearly as strong as the 55.......Cliff

Here's the vid with the square ground chain. I didn't see the big time improvement like I was expecting, but the wood I'm testing in is far from perfect. I only had room to make two more cuts with this chain before I ran into a knot. Anyway, it cuts well. Take it for what it's worth.

Here's some pics of when I was laying out the ports. The vertical pieces are on the very edge of the piston skirts. You can see that there was room for significant widening.

The intake port is offset.

Shipping label printed. You should have it back by Tuesday.

that little dude screams

 

[Taxmantoo]

What do you mean?

The wood seemed to have burn marks on it, like when you run a table saw with a dull blade.

Gotcha. I'll have to go back and look at the vids.

 

[mustard]

does anyone have an accurate dry powerhead weight for the 238 se ??

 

[parrisw]

Like this? LINK. Is this something to give my 346 and 260 a run for their money?

I got one of those 50's in nice shape too. Its got a bad piston. Are those 50's decent saws?

im watching this thread to see how the square ground does compared to round ground.

i have a few square ground chains i ground round and didnt see any decrease in performance. must be because i shouldnt have a saw in my hands at all

nice saw by the way

I allways liked the nylon screen filters better (44 micron, not the black bodied
80 micron winter filters).
They are easier to keep clean as well as less restrictive.

I used to like them as well, and they are good for using on live trees when its wet outside. A mechanic showed me how much crud gets through them when you are cutting dry and dead wood. You can feel the mist of very fine dust, where the filter meets the carb, inside the throat.

Something was smoking towards the end of those cuts. Last time I saw that it was a sprocket tip bearing going bad, you might check the bar.
