Compression testing

[Stihlbro]

I pulled 225 on my 026 with a junk gauge.

How does it run, how does it cut/ tune?

I build high compression saws and settled on one tester and don't worry about it.

225 isn't super high for a 026 is it?

I love this thread. These compression reading are just a reference. It is only a static reading. Too much variance with hot or cold. How much oil you run. What altitude your at. But one thing for sure is the Internet likes some compression.

@Redfin thanks for taking the time on your end. The results are not deniable.

This thread was meant for nothing more than the hose adding volume debate. Who friggin knows I may have mucked something up and its wrong.

My 034 is 225,got a 066 and a 394 that are 240,another 066 that's 230. My 064 hybrid is 225.

So how accurate is your gauge? Have you ever qualified it? How much is high compression? And why do you find it necessary? I'm curious?

There's a video in my thread (Stihl 026 rebuild). I would love to here what you guys think!! The 024 feels stronger. I don't want to high jack this thread.

I thought that saw with over 300 took a chit?

witch one? 440 head saw lost a crank real quick like.
361 was the first saw I was able to get to detonate, lowered comp by raising exhaust port. still runs fine.

I don't care if my guage is right or not.

It's consistent so I use it. It probably ain't right but it don't matter since it's the only one I use.

The 440. I remember you sayin it didn't last long.

Your test is valid. You did nothing wrong. I've found the same results. So now when you post a compression reading, should a person state what length hose used? How many pulls to achieve highest reading? Please don't take my post wrong, it's not what you did at all.

I've never had a problem with high compression.

I've read of guys going to 300 + or -

 

[Deets066]

Short hose or long hose won't matter. Just pull until the needle quits movin

So it is ok to say a high compression saw is what is needed to perform? The higher the better right?

Depends on what type of work the saw will be doing and what size saw.

What is high compression to you?

I don't know if that's true,I've found the higher the better but it's not necessary.

Strongest 066 I've ever ran was 230lb,but I got one that's close to it at 220.

 

[jmssaws]

What is high compression to you?

Over 220

 

[Deets066]

What is high compression to you?

I'd say 190-250
