<VV> SPYDER DASH IN FC

I have done several , including my Rampy.  I like having a tach and trip odometer. I put a voltmeter in the head temp hole. For a while I put small "motometers" in the vac/boost hole. Now they dried up. I find it easier to install the 2 indicator bulbs if you add @ 1 inch to the wires.  I took a junk rough dash housing , ground it on my belt sander , then painted it with black wrinkle finish. The same for the glove box door and ash tray.   Dont overlook junk looking spyder dashes.You can save them with a little work. I make a small harnes for all the dash lights with one wire  with a plug to a plug on the harness.  The rest of the plugs will reach with a little work.  I have saved harness parts from all of the cars I part out.
    The 8 door I am working on now is getting a Spyder dash. I took ALL wiring out , and will add wires and a length of shock tubing to the main harness before putting it back in. I guess I better take more pictures. There are a few on the website now   www.cnycorvair.comRegards, Tim Colson

Thanks - I understand the concept well enough - but I am amazed that I have never come across this in all the years I have been playing with engines. I have a sneaking feeling this is a US rather than a UK practice, and I intend to research this.I found an article where an engne rebuilder had assembled a V8 engine with all the marks pointing towards the camshaft. You can see their logic, but all the marks should have been to the right (or left, I forget now). The fact that it subsequently rattled indicates that the few thou involved are enough to make a difference.About forty years ago I had an Aston DB5 that had a horrible piston slap on one cylinder when cold. It was easy enough to identify the cylinder by pulling the plug leads off one by one, and I duly stripped the engine down. There was absolutely no visually identifiable reason why that piston would have made a noise, but I replaced it and the noise went away.If you want something really weird, there is an ancient British car alled a Trojan. It has a sort of V twin arrangement, but one cylinder is an auxilliary pumping cylinder. The weird part is that there is only one conrod, cast in the form of a V. On each stroke, this has to bend a little. I refused to believe this when I first heard it, but I spoke to someone who owns one and he confirmed that it is correct!

I think we are all agreed on what is 'right'. What I am trying to figure out is what is going on with MY van, as there are so many things that don't correspond with the manual - and also how I can get a working choke somehow!

________________________________Hugo,
I think it is quite possible that the add on panel under the dash (added because of the Spyder instrument panel) is where the choke would have been mounted - meaning, that panel is using or covering the holes for the choke.
And the thin pipe, needed for the Spyder dash for the vacuum/boost gauge, probably held the choke cable in the original configuration.
Well, that's my guess anyway.

I just put a second pair of specs on and stared at it a bit harder. Inmy book it shows a bracket in the front firewall for the choke cables.This has four bolts or screws. At least I thought it did, but with asecond pair of specs on it might just have two bolts at the top. Thethings at the bottom that look like bolts may not be bolts. On MYfirewall, I have a plate held on by two screws in about the right place.It has a hole, through which goes a thin little pipe which looks like avacuum pipe. Also my throttle cable goes through a hole way up high inthe firewall, not underneath it like the book shows.At the front of the car there are no holes in the dash, under it oranywhere near it. It does have an 'add-on' panel under the dash to theleft of the steering column. This contains the wiper switch and what Ipresume is a washer switch, although I have no washers.The intriguing part is that my ORIGINAL dash (not the Spyder dash thatis fitted) has the word 'CHOKE' engraved in a line with the othermarkings. But there is no hole or anything underneath the word CHOKE. Ifit weren't so damn wet out there (this is England!) I would crawlunderneath and see if there is any evidence of any choke fittings.Other than that, your last suggestion might be the most plausible!Except that the door handles tally with the early type, and it has agear shifter that is bent like a stick of liquorice and goes backhorizontally through a vertical panel in the cab. I believe this is theearly type & the later ones went down through the floor? Who knows whathas happened over the past sixty years!

Um, no change! The FC uses the same TEMP PRESS lamp for the same purpose of reporting oil pressure/head temperature warning.
And the GEN? lamp is also the same.

You are not the only one to do electric drill valve jobs!? I do the same method! Ha!
As long as the margin on the side and the pattern looks good, it is good.
