Any compression, set the exhaust where you need it concept?

Unbelievable work.

Did you check compression?

 

[Stihlbro]

Yes and it shows 120 lbs. lol! I used a 10mm plug which requires an adapter that I have tapped and installed a schrader valve. It's is false on the reading!

Ya think?

I struggle with compression testers.

Cool thread. This is stuff we like to see!

True story. I have 4 testers. I guess they are all junk. One snap-on, one Actron,one sun pro, one new one from Amazon. None read the same. I've tested against others. It just don't work for me.

Great work Joey!

OTOH, in have a lisle comp tester and it seems to be real accurate. Its never failed me and works great.

Keep up the good work man!

I just bought an OTC. My 4th tester, and finally one that makes sense.

I built a 262 that's ate starter ropes and bloodied my hand. Scratched my head wondering why I couldn't break 165 compression. It read 238psi on the OTC.

I have a Snap On that works well but eats valve cores regularly! I get valves from Napa for their compression testers. They have several testers but their deluxe kit is made by OTC im pretty sure

I got me a snap on from ebay cheap. It does go through cores a lot. I had a 288 that tested out at 185 on the tester before it and 235 when it got to it's owner.

What gives with that Mike? I cant figure out why? Maybe a spacer to get the valve alil farther from the cylinder? Just guessing

 

[mdavlee]

I don't know why. Might be all the higher compression saws. I rarely check one unless someone asks for a reading.

 

[drf256]

I think their inaccuracy is more of a rule than an exception. I used to check to make sure I had enough compression for the saw to run strong. Now I find myself checking to make sure it's not too much.

That's why I keep notes. I don't trust compression testers, and wonder if I am getting an accurate reading anyway. Trial and error is a better way to go. I've had a few 390XPs eat the starter pawls, so I decided I should dial back on the compression a wee bit. By my gauge, they are only blowing 190psi though.

Mine is about 205 down here in La. Randy. I hope u have all that info stored in an offsite data base? In case u dont send it to Keith Gandy @ kgkx125hotmail!!!!!
