Nitrous oxide injection is my guess. Or, given the pic of the throttle cable, discovering that the throttles weren't opening fully and now are. But I'll go with the nitrous.

For reference, the first law of Impdom is that there...

Maybe it will improve as the rings and bores bed in and blow-by, and therefore crankcase pressure, reduces. Obvious question but is the flame trap, if you're using one, clear? Or are you venting the crankcase to atmosphere?

Strange that the wear on the ring gear isn't mirrored by wear on the opposite side of the ring gear. You would expect the areas of wear to be 180 degrees from each other, because the engine is as likely to stop with cylinders 2 or 3 on the compression stroke as it is with cylinders 1 or 4.

That needle shows clear signs of wear at the base to my eyes, where it has rubbed on the jet. That's the part in use at idle, when the mixture is set. So a correct mixture at idle, compensating for the needle wear, will lead to a wrong mixture – too lean – further up the rev range. This could be the...

Re: A Californian drying out in South Africa

The earliest Imps to have the Pentastar were F-reg in the UK, so yours, Roy, is too early. F-reg ran from 1 Aug 1967 to 31 July 1968.

So don't go digging for Pentastar holes!

Re: A Californian drying out in South Africa

It makes sense to position a Mocal/Serck-type oil cooler, like yours, where air is drawn through it, as it is by the radiator fan through yours. Without air movement they don't do very much, unlike the Sport hedgehog item with its exposed radiating elements. But you knew that already.

Re: A Californian drying out in South Africa

Roy, I think you have the doughnuts fitted the wrong way round. The longer end of the bolt-tube bosses should abut the driveshaft, not be under the bolt head. The way you have it will cause the driveshaft 'spider' to dig into the doughnut under load and eventually cause it to split and fail.

Where it gets hazy is in areas such as the lower rear wing where it covers the sill. Is that structural or not?

Re: A Californian drying out in South Africa

Those Laycock pressure plates look well worth keeping. The drums are worth hanging on to as well, provided they're not scored or very rusty inside. Some of us still use drums on the front... which work very well on a small, nose-light car like an Imp, by the way.
