Hi,With the plugs out, the motor turns freely, as soon as I put compression tester on one piston, motor turns very slow, with pull-start motor also turns slow. That is why I'm getting a low 70psi. Can I use a 70 or 80 amp. battery to get a faster revolution or can there be something else wrong? Thank you all for your support.

A hefty pull with the recoil will get you proper test results.-----Perhaps there is a problem with the starter motor itself.-----------------What is the history of this motor ?-----Have you owned it for a while ?----Just got this motor , in which case you may have bought someone else's problems.
does it roll over well with all the plugs in? with either the e-start or the pull cord? does it make any knocking sounds with the comp tester installed? i remember a post from awhile back where a person spent a a lot of time trying to figure out why his/her motor would spin free with no plugs, spin a bit hard with plugs in, and knock or lock up with a compression tester installed. it turned out to be that the wrong ( slightly to long ) adapter was being used on the comp tester. ..just a thought!
