LOL!! I understand completely! Thanks anyway. However, I have managed to create some very quick motors through adding a little duration to the opening and closing sides of the crank (more on the closing side), fanging the sleeves and a few other tweaks here and there. I have a trick TZ-18 with a 9mm carb on it that is absolutely amazing. I guess the biggest problem I've had is not watching the motors close enough, because I have blown up a few! Absolute screamers though!
