100psi cylinder compression.

Bit demoralizing. Got a Ryobi very cheap: cut two small bushes/trees, saw cuts out and won't start. Spent 4 hours, two spark plugs, two different carbs(guy have me an old spare engine with it) and a can of Holtz. Saw has 100psi cylinder pressure,which is enough to get it going on the Holtz, soon...
