sorry I can't seem to load videos to scimitar web.
You can't - but you can add Youtube links (and if in the right format - Jim did a "How To" - they can be embedded).

When you say both 3 and 6 have a spark, is that with each plug removed and tested, or a spare plug attached?

Ignore my last - sort the variable timing first. That can only be the dizzy at fault.

Dizzy is off, following some advice of Facebook I've checked the shear pin, which seems fine. Vacuum advance also seems ok, as well as the weights.

Videos on the Facebook thread here.

The one thing I did find was that one I put the plate back on the lever for the vac advance was a bit low and the plate could move. I'm not sure if I induced that fault taking it apart and putting it back together or it was already there.

Rat Rod (might be fixed?)

Post by Gillsfan » Sat Sep 26, 2020 4:57 pm

I seem to of got somewhere. Retimed after refitting the dizzy. It ran and revved without backfiring, checked timing and it had moved slightly adjusted it back and whilst doing it noticed it move as I put the ratchet on. After messing about and scratching our heads, we have worked out (we think)that the vacuum hose isn't in its elbows far enough and it's getting knocked/moving and affecting the timing. Additional checking plugs revealed that they aren't in good shape, the spark from number 6 was very weak. New plug in and 6 is now firing correctly. The gaps were wrong on all of them and moving the plug from 3 to 5 moved the fault. So new plugs and longer vacuum hose and see if that improves things. I've also found a possible leak from the master cylinder to the servo, I may have found the braking problem as well (fingers crossed).

If your timing is moving then check the length of the securing bolt as it could be bottoming out in the block

Better to be an hour early than 1 minute late

Which "Shear pin" is this Steve??.
After working on Essex engines for over 35 years I have never come across such a part :shock:

I'm reasonable confident that the dizzy isn't moving, but I will double check it. Thank you

I think it was the roll pin that was being referred to. That's what I took it to be.

Hardened spring steel roll pin :o
The gear is also pressed onto the shaft :o
I have had to destroy the cast iron gear in the past to rebuild dizzies :o

WTF I give up :bh

Rat Rod (mobile timing)

Post by Gillsfan » Wed Sep 30, 2020 3:24 pm

I've fitted the new plugs and vac advance pipe. The timing is moving. I've set it several times now and after a rev/run the timing has moved. I took the dizzy out and tried the old dizzy(points) I could get it to fire, I turned it over with the cap off to try and watch the points working. I melted the points, I turned it over a few times and it resulted in smoke and a small flame 🔥. So I tried in desperation swapping the electronic ignition to the old dizzy. It fired straight up and I set the timinh, a bit of a rev and the timing has moved again. I marked the position of the dizzy and I'm confident it's not moving. Arrrrghhh help.

Is it still able to move spring loaded a few degrees? And more importantly move back?
