atc70 help

[haydo111]

firstly let me introduce myself my names hayden and im from down under Sydney Australia ive been bitten by the trike buy and try to buy one when I see one atm I have 2 atc70 trikes a little alt50 and a Kawasaki tecate I love them all
MY question is
one of my little 70's was working perfectly last time I used it (about 6 weeks back ) put her away and tried to start it and it would not kick over not even when I put gas down the hole so I run a quick compression check 60psi WTF
from my experience it could be either rings /piston head gasket or valves
anyhow every part I get for these little guys I have to get sent from the states 2 a little over 2 weeks each time so I kind of wanted a little input before I start ordering away
1 what would be the mostlikly cause from just sitting there to drop so much compression as it was working perfectly before im hoping its an easy fix but I havnt had the head of yet
any ideas before I start

Pull the top end and inspect and mic .
Might be a tight / leaky / bent valve who knows .

Just valves and timing . Not hard just download a manual and follow the steps .

Could timing chain have skipped a tooth last time it was shut off, or trying to start it?
