how would u tell if u advanced your timing to much?? would it ping or what? also how many degrees is between the yellow-leading, and the pink-trailing marks. that way ill know how much i actually advanced it. im suppose to run higher octane gas when i do the timing or not?? thanks

Overly advanced ignition timing will cause it to detonate.
The leading mark is at 5-degree ATDC.&nbsp The trailing mark is at 20-degrees ATDC.&nbsp There's a 15-degree difference between the two marks.

I heard heavily modded n/as can run 30 degrees for their race engines. But thats for racing and is dangerous
I think I heard somewere that 24 degrees is ok for say an n/a heavily modded but for the street. Dont take my word for it thou

i lost an NA engine to timing being too advanced, and it only took 1500 miles to do it. made some hella power tho.

rotorhead how much did u have it advanced
?? and someone tell me do i need to up the fuel to 93??

93? man the premium on the west coast is 91 now. you guys suck :P

heheh sorry nothing to do with the post

to do it right you need a gun that can adjust the timming on it. so if you want to advance it 5 degrees. you advance the gun 5 degrees then align the mark. I wouldn't try to guess by how far off the marks by turning it using a cheap timming gun.

i jumped the cas one tooth and set it all the way counterclockwise. at the time it was all i could do to get the engine to idle. i didnt have a timing light at the time so i just listenned and felt what the engine was doing. it made power beyond redline with that timing setting.

after i lost the engine i got to reading on timing, and found that if you install the cas properly, you can't advance/retard the timing too far without taking the cas out. you should be fine with adjusting it from the factory setting even to its maximum adjustment limits.

Where did you read this?
Can anyone confirm this? It SEEMS logical but...well...car designers are seldom logical...

fsm combined with a little mathematics. count the teeth, then devide that number into 360 and you get the number of degrees per tooththen use a protractor to find the degrees that the adjustment allows and devide by 2. you devide by 2 because factory setting is right in the center, and you are left with the amount of degrees that you can adjust in either direction advance/retard. it has been a few months since i did it or i would give you all the degrees, but i dont remember.
