Looper Shutdown with a rattle noise

Holy cow Andrew, if it wasnt for bad luck you'd have no luck at all. Hang in there, this too shall pass.

Thanks Guys for all the kind words I am feeling much better. All my test came back negative. Low potassium was the culprit for the chest pains, I have since added OJ and bananas to my diet.
Hopefully they will add potassium to my beer and I be ok.
I pull both heads no sign of damage. Maybe broken reeds ?

check the flywheel nut, make sure the flywheel is tight. I had a merc that was making rattling noises, found out the flywheel was loose, had to replace the flywheel.

You need to find where your compression was leaking. Broken reeds will not cause low compression unless something is jamming them closed and not allowing any air past.

Please see the flywheel photos on this link http:\\www.nymack66.com
As for the flywheel been loose I will check since I did pull it off last year !
What is the correct procedure for a compression check I disconnected the fuel line remove left 3 plugs in and connected to one cyl crank the engine about three turns. Is this correct?

9 amp charging so not a magnet issue. you could pull the carbs and look at the reeds or heck pull the reed body and look in the cylinders and turn by hand till each rod is at the hole then rock to see if you have a bad rod bearing or loose rod cap. those rod caps use either a 5/16 or 8 mm 12 point socket. must be a 12 point. you can check the torque of the rod cap bolts threw the reed holes as well. that 12 point 8mm is avail. at sears.

Guys,
Why is it the pistons are really loose ? Is this normal ? Is it possible the previous owner installed the wrong set of pistons in a re-bore sleeves?
