Compression tester?

[brownie545]

Hey all,

Can anyone recommend an accurate compression tester? Just did a rebuild on a 787 and I'm getting 110 on each cylinder with my harbor freight cheapo. The ones at my local auto parts store look just as cheap.

Thanks

What did you do on the rebuild ‍

 

[brownie545]

Top end. Pistons/rings.

Did you measure the cylinders before deciding on pistons?

What was the reason for doing top end ‍

Compression before doing too end ?

I have had good luck with the Bosch and Actron ones from Autozone.
The Harbor Freight ones are well known to be junk and read low.
