The increased diameter also makes it 'easier' for the starter motor to rotate the engine this setup is similar to gears on a bike, a low gear requires a larger force to be applied in order for the wheel to rotate whilst a higher gear requires less force but the amount the wheel rotates is less.

Flywheel with Gear Teeth Tip: The flywheel diameter is usually large as this allows it to rotate further from the crankshaft centre axis of rotation an imaginary line that runs through the middle of the crankshaft.

The correct answer is worth at least a beer! Super thanks in advance, Eric. Bump for a reply? That said, i don't know the tooth count by hart. I'll try to contact a buddy of mine who has a 12HT apart at this moment.
As soon as i know the count i'll post in this thread. Later, Mark. Eric, Just got the email with the tooth count. There are teeth on the flywheel. HTH, Mark. I believe those flywheels are diferent size one 2H,12H-T.
Mark, that does help a lot! Did you count them or was it listed in a book somewhere in the Netherlands? Also if you did a manual count, which flywheel did you look at? I was guessing by looking at an oscilliscope and then climbing under the engine while it was screeming at around RPM with a hand-help optical tach!
Click to expand Eric, A buddy of mine hand counted them from a 12HT flywheel. He bought an extra for parts, so it was easy for him. Joined Mar 28, Messages 4, Comparison at the shop today: Both flywheels take a mm clutch disc.
Greg, YES! As I look at the Speedway Motors catalog, for example, the main difference appears to be the bolt pattern, not the tooth count, which isn't even mentioned. Jegs offers chrome OEM starters in tooth only, as does Summit. Am I concerned with something that make no effective difference in replacing the starter? Considering the huge.

Thanks to all for taking time to respond. Jeez Dennyeven you should know the answer to that oneYa leave one bolt out We've needed some humor on these posts. Leave it to Denny to throw some stuff at us It turns out that I didn't have to replace the starter after all.
In order to test the cranking voltage, I had to disconnect the ignition wire at the solenoid, and while doing that, I found that the positive lead stud on the solenoid was loose. Once I tightened that, the problem was solved. Now, the starter hits full speed the instant I turn the key - no more intermittant slow speed problems. The cranking voltage is slightly low, but the starter seems fine and the engine starts immediately, so I'm going to ignore that for now.
