Another year to forget, got the car going for the first time in 6 months. Apart from losing somewhere to live and everything being in storage, I was mid-tweaking of the Qjet and had long forgotten where I was at. It got worse before it got better, and notes I took were not matching. Anyway, got it running nicely, started new notes of current settings and adjustments to refer to, meant to check the timing, can't find my timing light. To be fair, it could be packed away anywhere in any box over 3 towns, and no access to most.
So I called in at the local auto shop, they had cheap versions, in quality, not so much the price, but figured I want it for this week, not drive around to several towns or wait for one to turn up from ebay etc.
Car running nicely, but timing light.....nothing. Very basic set up, spring loaded clip for lead #1 and clamp for each battery terminals, no screen or readout. I checked basic fit, nothing wrong or bad grounding. Annoyed, thought I'd got a dud, and because I wasn't passing that shop in next few days while it was open.
I went back to checking a few settings on carb, gave it a rev, noticed brief flicker of timing light. Hmm....few more tests, not very convincing but it only comes on at higher revs when held, and still a but flickery.
Says in the booklet of fault finding that it may be a sign of poor grounding, incorrect clip orientation, bad light, but also low voltage through wires, resistance or breaking down of wires or plug gap too small, basically it isn't sensing the current until the extra juice is applied.
In theory there's no dramas, running nicely, has DUI big output HEI, new leads, plugs etc, gap is less than stock but correct for mods.
Anyone had this before? Probably not an issue with my better light, where ever it is. When I get more time on the weekend I'll try again just for kicks, swap a different lead type in place or regap plug 1 only and see if it notices. Just annoying as something so trivial, that I didn't really need to do, didnt really need to buy, had to pay far more than it was worth only to find it can't do the only task it was meant to do. And then also out of time and money, for no gain than a brief boredom cure!
