3. What do i adjust and how do i do it? (Oscar, this is where you step in with pics.. )
Damn, I missed my cue. It's too dark for pics now
The only pics I have don't reveal much.Ummm
Fuck it, my camera has a flash I suppose
The pic below is taken from in front of the engine, the black dizzy cap is to the right. Smack bang in the middle and in focus is the dizzy retaining hex bolt that you need to loosen, don't
remove. (it can be hard to get back in). You'll need a 5mm hex attachment that you can attach to a socket wrench and extension shaft, or, use a very long 5mm allen key. Once loosened, the dizzy then can then twist either way. Just like what Andrew says - Clockwise is to Retard, Anti-Clockwise is to advance
. Do it whilst the engine is running. You'll hear the revs pick up when you advance and drop off when you retard.
You don't need a timing light as such but it helps for record keeping. I use one but when I'm mucking around trying for max advance I advance it, go for a drive, pull over, advance some more, drive, and keep doing so untill I get some pinging then back it off a little, retarding it until there's no pinging under any circumstance. When I've advanced too far the first signs for me are pinging on hard acceleration with engine warm. As for pinging itself, it's only thru this forum that I learnt what it sounds like last year. Like a steel nut rattling in an empty tin can. Anyway, when I get back to the garage I then put a timing light on to see how many degrees I end up at.
So yeah, basically you can adjust the timing without a light and no need to remove dizzy cap either. Just advance the dizzy a little at a time to get max advance without pinging under hard acceleration.
Oh yeah, about degrees. Look around the edge of the vibration dampner, the end of the crankshaft, where the lower pulley hub is. You'll see markings around there like a ruler. No pics sorry, it's def' too dark now. By using a timing light, once connected, it will strobe once every time a spark travels thru the first ignition lead. Aiming the light at the timing marks and the marker on the block, you'll be able to tell how many degrees advance or retard you end up at. Check the Haynes manual. Pretty sure there's pics of it there.
