traxxas 2.5 compression question

[creterunna]

how do you know if you have good compression?
i took muffler off and held finger over pipe
wasn't strong but some air.
should it be enough to blow thorugh/aroung finger?

Try turning the flywheel with your finger. If its hard to turn, you have good compression, if not, then not good compression.

+1 To that!
If you can turn the flywheel easily, time for a new engine.
