RE: LOWERING COMPRESSION
Thank You for all the replys, I now have a better understanding of the compression and nitro question.
One last question, how do I determine if I have a Pre-ignition (too much nitro) and detonation problem?
I had a Magnum .61 and I ran 10% nitro, the engine ran great for about 1 gal. then the engine blew (rod or crankshaft broke), Magnum did replace the motor with no questions, could I have been the cause? I use 10% in all my engines (GMS .76, Evolution .48, ASP 1.08) except my Supertiger 2300 which I use 15%nitro and 15% oil and #F plug to make it a little more reliable.
