Just out of curiosity, I have read about motors having the timing locked in. Does this mean for example that it would always have 36* no matter what rpm? What is the reason for this?

yes it will always be the same all the way thru the rpm curve the reason for locking it is to keep it consistant with a mechanical advance it will change from time to time. it's a little harder to start up,but you can over come that by getting the motor turning beore you turn the power on to the hei

I have to agree locked timing for most race cars. Think about it if you have a mechanical advance all the advance is in by say 3000 rpm anyway. Most classes of circle track cars will always be above this rpm on the track racing so the timing never changes during racing. By locking the advance you take out the possibility of the weights or mechanism failing and tearing up a distributor or more. If you run a class where you drop below your max advance rpm then maybe mech advance will help but i dont think there are too many classes this will applly too.

Locked is the way to go. It also makes setting timing easy.(at idle if you like)
You can have problems with the advance mechanism that could cost you a race, if you
can eliminate something that is not needed it
is a plus. I have never had any start problems(I have always used a high torgue starter)

locked timing @ 36 degrees last year and been trouble free ever since, stock starter and all on a 10:1 engine, just hit the button then flip the switch and guess what Its off to the races heheheheheheh
