I tried to check my rebuild 064 but guage goes down faster than I can pull!

Ya I hear you! Its frustrating when I have the same 200$ snap on gauge that Brad does and he hasnt changed a core in 2 yrs and knowing he test probably 100x more saws than I do! What the heck gives??? Mine works great as long as the valve holds. A standard valve core reads around 30psi lower than the reduced spring pressure core
Called Napa and ordered six valves they will be at the store by Noon tomorrow! Ill check my 064 right after that!
I'm going to start handling mine with kid gloves, lol. Are you guys testing hot?
I have never attempted when the saw is hot!

Usually cold
Have you checked to see if the core is just loose? I've had that happen multiple times.
I thought about that but never did!

I have. Never found one loose

If the standard tire core valves run about 30 psi lower, why not just use one of those and figure +30 psi? they last forever. I put a standard tire valve core in my tester maybe that is why my saws only read about 110 psi.

Thats
no doubt why its reading low or the gauge itself?

I just ordered a 5 pack of the Balkamp #BK7009556 valves. I will compare them with the standard tires valves readings. If the tester valves aren't worth a crap and the tire valve give a consistent lower reading of say 30 psi low. I will use tire valve cores and add 30 psi.

.
If I had a saw reading blowin less than 140psi i would be looking at the gauge or my saw?

Why? If the saw starts good and runs great. I don't worry much about compression psi or even bother testing unless I have a problem. It is a trouble shooting tool.

more power to u brother
You guys and those $150-$200 testers make me fill good about my $15 one. 
I've tested my $15 dollar tester against the high dollar ones and they read the same. Only had 1 valve give me troubles so far in 8 years of use.

That's why I waited for a real good deal on a used one. Too many of the cheap ones failed on me.You guys and those $150-$200 testers make me fill good about my $15 one.

So if the saw starts cold within 3 pulls, and runs great, you will tear it apart because it doesn't have 140 psi?
I would, if I knew my gauge was accurate.

If it only has 110psi the gauge is bad, u have a problem somwhere or the saw is worn out on its last leg but I can bet u that its reading very low because of the wrong valve and not ur saw?
