  1. Setting ignition timing

    in Engine

    Posted

    Hi. I have a dizzy with the Vernier adjustment gauge. At the moment the timing is set up pretty accurate I think, though is on it's maximum retard adjustment on the Vernier adjustment wheel.

    Thinking it would be an idea to have the the timing set correct, with the Vernier wheel in about the middle of its range, so allowing any further, easier, finer adjustment.

    So thinking, if I set up a bulb to do it statically and when the points open for any cylinder (whether on compression or exhaust stroke) and bulb lights, then advance on the Vernier to half way of the range, then retard, by moving the body of the dizzy until bulb lights.

    Would this then give me pretty much my original timing setting.

    Hope this makes sense?.

  9. Trouble taking apart master cylinder

    in Braking System

    Posted

    I've done this job a few times easily (including once before on this original Girling).

    I'm pushing the distance piece down to release spring tension, though can't manipulate the end of the valve spindle into the right position of the keyhole, so it releases?.

    Any idea what I'm doing wrong please.

    Thanks Dave

    In fact packing roller bearings with grease can be a bad thing as it gets churned and if trapped generates heat...

    Thanks folks. I never overpack the fronts with grease, though use the grease gun on the rears every couple of years, though only do about 1500 miles a year.

    It normally takes a good few pumps before grease (which looks like the older, as I have alternated between the black and brown, not on purpose, just what was there at the time!)  comes out of inner side of hub (so guess it must lose some, though no obvious evidence of this, as not sprayed around anywhere visable?).

    So maybe overdoing it, though no way of knowing, and probably overthinking it (as usual).

    Thanks

    Most shafts you buy will be from cars that were dismantled when they reached the end of their mechanical life in the late 80s (bottom of the value curve?), so it makes sense to me most used shafts are in such a condition.

    Thanks, and neglected with servicing as well often, I assume (front trunnions breaking after 10 years, etc).

    Saying that, if the bearings you've found to be ok, does the shaft wear, regardless of regular greasing?

    I've taken something like 10 of these apart, all removed from scrap Heralds in the late 80s. I think out of 10 I got 2 usable shafts. None of the assemblies had failed bearings, but on all of the 8 scrap shafts the needle roller bearing had eaten into the shaft.

    Wow. Did the hubs turn smoothly with the shafts off the car, and suggest they were ok?

    Also, it does make you wonder if they may do a fair few miles with some wear on shafts?

    as with any cable drives the inner must engage the right amount  not too short not too long for all to work well and less flicky needled 

    Mine flicky (intermittently) at idle only. Any idea if outer cable needs shortening, or lengthening?.

    I did lube it ages ago, though, that made no difference 

  15. Stromberg CD 150/175 diaphragms. Are they the same part?

    I thought I sold you some 150 diaphragms at the Twiddle Day before last? They should last longer than this, I still have some from that batch I haven't need to use. 

    You certainly did Doug and there still holding up admirably, thanks.

    Because I'm a bit paranoid anyway and do longish distance touring holidays in car, any breakdown that can't be fixed at the side of the road, would be a right downer.

    So, I though it could be a good idea to slip them in to my shoe box of small bits that could fail, that I put in the the boot for these trips.

    Would like to buy another pair off you please, if possible?. 

    Unless, anyone else needs them more urgently?, 

    Thanks

  20. Loss of brake pressure, but has fixed itself?

    i doubt Dave drives hard enough to vapourise moisture laden fluid 

    You know me Pete (though when you overtook me on the M way going to Twiddle Day and doing a disgracefully slow speed of about 50mph, I was a bit lost and trying to look at road atlas while driving, I would have been powering along at 60 otherwise).

    Yes, best to change seals.

    The thing that made me think there maybe ok (and maybe just debris behind the small seal), was that the pressure was lost while stationary (rather than harder braking) and didn't lose pressure again when I tried the next day, even when braking hard (though not at fast speed). Though I don't enough about this, for example, does that seal have to hold a lot of pressure (out of interest)?

    Thanks for input.

    Had a loss of pressure, partial and straight down to the floor. Would build pressure back easily with one or two pumps, though lose pressure again moments later.

    Thought it likely the small seal at rear of Master cylinder chamber had failed.

    Obviously stopped using car. Next day I tried it and seemed fine, went for a couple of slow drives around the block, using the brakes a lot, though stopping at times for a bit as well, to see if they lost pressure.

    Appears to be no loss of fluid. Thinking maybe seal hasn't failed, though maybe a bit of crud behind it at the time?.

    Seals have been in there about 8 years (reluctant to change, as a matter of course, due to likely repro crap) and changed fluid 3 times in that period, (last time maybe 3 years ago).

    So, if it is a bit of crud, maybe clean out Master Cylinder?, or any other advice would be great please.

    Thanks, Dave

     

       

  24. Can ambient temperature affect mixture

    No, it's usually fine. This is partly because the summer setting is normally slightly rich, and the engines are quite tolerant. It's more important to get it right for emissions reasons. Also, in winter, the engine probably doesn't get as hot, and most of the "weak mixture" problems are caused when things get hot.

    Thanks, Great, as difficult to get this sort of info (even though, it's sort of basic)
