can someone please explain dwell

[mark]

was told to set a mates engine up with 30 degree dwell. what is it?

[firekdp]

It's the number of degrees that the points must remain closed to allow the flux to build up to a sufficient level in the HT coil in a battery powered ignition system.

so it dont matter in an electronic system

[firekdp]

Correct, it doesn't matter.

Yeah it's quite easy really, wait for it.....................

Or are you talking dwell period? the amount of time/degrees the inlet port is clear of piston? as you stated 30 degrees I suspect that may be what you mean?

[sean brady scooters]

this also crossed my mind when i saw this post,
dwell in terms of inlet timing is the amount of time that a port is fully open and unobstructed,

I thought the 'dwell' is where the 'dwater' came from!














Sorry, i've been on the ale........... :bouncyeng:
