RE: How to check engine compression
G'day Mate,
That is completely normal, I have two 46AX's, & they were both tight when new unrun, but they bed in & turn over easier, but with plenty of compression.
When you flick the prop over compression, does the prop bounce back & forth? If so then bearings & compression are OK.
Only start to worry if it won't start & run smoothly, then you may have a problem.
