whats good compression on a wave jammer?
Just what the title says, I ended up getting one for free that was in a basement for 9 years, thing is in very nice shape, seems to me all it needs is fuel lines, just curious what good compression is on these 500cc engines, they are both the same psi, just curious if its good or not (Numbers not in this post, want to see what the experts say first )
This is a stock machine. Thanks again in advance.

per factory service manuel.. 142.2 lb.... if you give it a 10% loss... you'd be good at 128...I'D run it rich for a while to help wash it out ... factory says 25 to 1 first 10 hours 'new' ,play it safe... that carb rebuild is an easy one...a 'jammer is even easyer than a 'runner to work on if the motor is in the hull

they read a about 138ish both side.
nice thing is someone spent a lot of time on this machine, fuel tank was tankin out and completly washed out, new starter was put in, new impellor,ride plate and intake grate as well.
I really made out on this thing, i might fire it up today

clam shell hood is no prize...cant count how many times the support rod has been knocked loose!!
the jammers compartment is more open in width and also not as deep as the wr's..
