timing

[roadboy]

hey, i did a search on supramania and the guides, everyone says to put it at 10btdc
but i had my car set at 0 because thats what tsrm says, should i just leave it at 0 or change it to 10btdc?
any input would be nice. thanks

Which timing are you talking about?
Cam timing requires the crank to be at 0 degrees to properly set it up.
Ignition timing requires a timing light, the diagnostic connector pins E1 and TE1 to be shorted, and then you aim for 10degrees BTDC at idle, fully warmed up.

Here's where the actual timing is set:

If you're thinking about cam setup, yes, the matchmarks at the top should be lined up when the crank is at TDC.

im just putting my timing belt on it should be at 0, and to set up my CPS it should be at 10btdc correct?

Yes set your crank at 0 and make sure the marks on the cam gears match the notches on the timing cover behind them. Once you put the belt on, rotate the crank a couple times to make sure all is still lined up. Then, jumper E1 and TE1 and set CPS with your timing light to 10 degrees. Once you remove the jumper, the timing should automatically change to 14 degrees.
