Nothing in AN 35 states that a compression check has to be done at 100 hours AN35 para 3.1.1 only calls for an "inspection" however it refers to a chapter of CAAIP's that recomends that this is done or the prop pulled over to check the compression.
I think that I will continue to do a comp check at each 50 hour check but it is not a requirement it is all down to the engineers discretion.

It is my feeling that engine life is down to regular use and oil changes more than hangarage ,if your engine is usage then the Shell oils with the corrosion inhibiter seem to help.
Hangarage however is a big factor for the airframe and avionics , it is my opinion that the money that you save with outside parkng is more that ofset with the extra maintenance costs.
