YOUR THEORY IS THAT FOR A 1.OOO BORE DIA. THE PORT WIDTH CAN GO AS FAR AS .750 WIDE. DOES THE OVAL SHAPE NEED TO BE TRUE BECAUSE THESE TORO'S HAVE A RECTANGULAR PORT AND I CAN ONLY RADIUS THE OUTSIDES AND THE TOP AND BOTTOM NEED TO STAY FLAT OR THE TIMING WILL BE TO GREAT. THE PORT IN YOUR PIC DOESNT LOOK TO BE ANY WHERE NEAR THE 75% YOU TALK ABOUT. AS FAR THE WEIGHT GOES IF A 30CC WEIGHTS LESS THAN THIS 25 TORO IN WORKING ON I MUST BE CRAZY FOR WASING TIME ON THIS ENGINE WORK. I SHOULD JUST GET A BIGGER ENGINE TO START WITH AND HAVE THE RELIABILITY OF THE STOCK CONFIGURATION. THIS TORO IS GONNA WEIGHT 3LBS 5OZ WHICH IS A LOT MORE THAN THE HOMILITE 30 THAT AV8TOR TALKS ABOUT.
