Whilst pondering my next move I have returned to UNJ.
Although it drives well it's always had a fair bit of "pinking" so this afternoon I got round to checking out the timing.
It's supposed to be 10btdc but when I checked it was off the marker! Must have been about 14+.
Adjusting isn't so easy due to the amazingly difficult to get at bolts that hold the distributor in but with some perseverance all came good and I reset it to 8degrees btdc eventually (not standard due to lower octane fuel nowadays) and it certainly has improved matters greatly.
Then I moved on to trying to fix the non cancelling indicators but wasn't so succesful - ho hum, another day maybe.
Meanwhile, with the other cars I continue to ponder although it could be the 2000 that gets attention first as I am starting to miss it!
Here's video of us on the Little Devils in BRP where it's certainly possible to hear the engine rattling away!
