SER1 Valve timing

[prev] [thread] [next] [Date index for 2004/08/10]

I have heard that the S1 engines are very senistive to slight valve timing
errors.

I am confident mine is spot on, but would be interested if anyone has
experience with how much error is required to significantly effect
performance?

As far is hill climbing is concerned, I use mine in very hilly territory,
and found huge improvements by playing with ignition timimg.  I put the
vehicle at the base of a short steep section and repeatedly drove up and
then ran backwards down, adjusting the ignition a little bit each time.
Very slight adjustments made a huge difference in the ease with which it
climbed, although the process took over an hour.  To do the same with valves
would be interesting but too time consuming.

I hope it isn't over advanced, but I with the compression ratio detonation
is not a problem.
