I'm so sorry to hear that.

Yeah, what can you do :)

Was fun, had it a long while, and by the time I sold it had gone up in value enough to cover the cost of all the parts thrown at it over the years :)

Alloy block ordered, and is this okay for an insulator?

Ferpickt.

Though, do you need one?

For carbs, the reason was to stop boiling fuel in the float chamber, however with a return fuel line, the fuel never hangs around long enough to boil.

Or is it for performance? Keeping things cool etc :)

A certain forumer used Asda chopping boards to make a spacer for his TBI unit :ph34r:

You don't need to over-think this stuff - as long as some petrolly air can make its way into the engine it'll run, the rest is just polishing!

I need the clearance to fit the TPS cable. A block of this should do it, with a scoop out of the alloy.

In the absence of a mill, would a wood working router mill aluminium? It would cut tufnol, for sure. Right?

I'd like to step the adapter where it meets the insulator.

Absolutely, knock yourself out.

Plenty of examples of that on YouTube -you can put a nice chamfer on the edge as well :p

The only issue I've ever had is the cutter getting hot with friction,, and then cutter/blade attempting to melt the cut, and failing. Thus not cutting anything... but that was nylon.

I think I'll be doing this in very slow stages.

Shout with what you need milled, I'll get it done for you.

Thanks, I'm tempted, because I'll muck it up.  But I've bought enough to make two, so I'll have a go first. 

When I do mess it up, you'll have some post!

This is how I'm going to mount the adapter for the carb.

I was going to bolt through the exhaust holes. But that might interfere with the exhaust.

Then I thought about machining an insert that could be tapped into the hole,.......

 

D'oh! I have some already!

 

My bigserts! From when I fixed the cylinder head on the TDI. 

Here's the plan.

Am I missing something - why not bolt it to those two threaded holes? :huh:

The flange of the throttle body is wider than the two holes. I think.

And the holes interfere with the TPS wire.

I'll offer up the throttle tomorrow. It should make more sense.

TPS connection would be over the nuts.

Can you unbolt the TPS and flip it 180?

I could, but there's a redundant mounting cast into the throttle that I'd have to grind away. I'd rather not.

Countersink the two hole's in the adaptor and use bolts instead?

That's another option. I'll think about it. I think my current "plan" fits with the series aesthetic.

But, I've to finish the engine first!
