500 firing order...

[chris1972]

Okay, I've been a bit of an idiot.

Changed the dizzy cap and rotor arm this morning. I marked the HT leads, but some of them came off when I was swapping them over. Fired it up and it doesn't want to know! Can anybody give me the following:

Firing order
Which cylinder is which (diagram very useful)
Which is number 1 on the dizzy cap

Thanks peeps!

Turn engine to TDC on firing stroke, the rotor will be pointing at No 1.

The worst that can happen is that you'll be 180 deg out!

[chris1972]

Thanks. Need the firing order to ensure all the remaining HT leads are correct too!

That link should show firing order, if not put RV8 firing order in images.

1,8,4,3,6,5,7,2

I see it now... couldn't get it on my Blackberry!

Top tip from me having bought a Chim in June, if its working don't fiddle with it. Like you I did the same, then I had to replace the vacuum advance on the distributor and buggered up the timing and stripped the threads in the distributor housing
Honestly if they're running, I believe they will continue to do so without our tinkering

Blimey, sounds like a job...

Mine was running a little rough, missing a bit, so I'm putting this down to something in the ignition. I started at the obvious and cheapest place. Looking at the dizzy old cap, it has seen better days. I'll go out and do it properly tomorrow. Failing that, it will be plugs, leads and coil... it shouldn't bugger things up too much (I hope).

Whats that round thing

Good luck Chris. Should be fine changing those. It's the base plate I thin the distributor I knocked, unless you remove the vacuum advance (where fitted) you won't have the problem.
I got my leads, distributor cap and rotor arm from here:

Excellent quality and value.

Hi Chris one thing to note if removing the coil etc, if you remove the amplifier to clean or inspect make sure all the brackets are very clean as the amplifier earths through the plate its mounted on, then bolted to the bracket on the plenum and no earth means no spark (i found this out last weekend the hard way).

Thanks for that. Every little helps!

I'm afraid that will vary depending on how your dizzy was oriented on installation. You will have to fnd TDC..at least approximately. Do you know how?

I still have some of the leads marked as per the old dizzy cap, so should be able to work backwards from those as to the positions of the remaining leads. However, it would be interesting to know how to find TDC. Does the crank/ cam pulleys not have marks on them?

[LuckyLucky]

Yep, marked on te flywheel although hard to see!

Get in there, clean off the area and mark it and the pointer on the timing cover with a dab of paint.

You then can check where the rotor arm is pointing to ( No 1) unless you are 360 deg out on the flywheel.

I though the dizzy cap only fitted on one way???? Does it not have a notch on the inside?

Yes it does, so it will only go on one way.

Thanks, I should be able to work it out from the markings then!
