I was sitting here in the subfreezing temps wondering about some things. One thing, other than fishing on the boat in the summer, was if its high combustion temps on a johnson/evinrude crossflow or any two stroke for that matter that cause the carbon problem would it not be wrong to try to lower the temps somehow for that extra margin of saftey. I know that setting up a motor properly it the first step (i.e. not lugging the motor.) but a reduction in timing will also lower the combustion temps quite a bit. I run a small block chevy nitrous oxide motor and we routinely lower the timing on the "juice" cause the cylinder pressure and temps go through the roof. In my experience the more efficient a motor is the less timing it needs and or will tolerate. These two strokes seem to be fairly efficient and quite powerful for there size. I also read from one large powerhead remanfacturer to back the timing from 28 to 24 degrees on a crossflow does anyone recommend doing this and how much power could you expect to lose? Would you even notice the power loss and would it help the motor any? What are your recommended timing suggestions?<br /><br />Sorry for the long post! <br />Its only like 20 degrees here and we are looking at a big snowstorm this weekend<br />SUMMER SEEMS SO FAR AWAY\<br />Thanks for the replies in "advance" sorry for the pun I couldn't resist
