RE: help me !! DL 50 rpm are not here !!!!! ? why ?
I have two DL50's, one with high compression, one with very little. Guess which one turns the higher rpm with the same prop, that's right, the one with the lower compression. I spoke to Bob a DLUSA because I didn't understand why. He said the factory switched to a different piston ring that results in the lower compression, but more power. Both engines run great!
