Scimba - Just add fuel

Quick update. After cleaning the carb thoroughly once more, including rodding the galleries with some bits of guitar string, the Scim will just about run. I've even managed a couple of trips to the petrol station in the next village! But the good times don't last. Not long after warming up it starts...

That's very good of you Mark. How much for a pair? They are 70mm total length including 7mm threaded at the top. The bottom is tapped to a depth of 20mm - probably more than is necessary. The fittings are M5.

Carburettor query

Looks like a Weber 38 to me but the experts will be along shortly. I've just replaced my idle jets with new ones bought from Classic Carbs UK. Part numbers are 74403.45 and 74409.45...

Scimba - Just add fuel

All seem OK Jim to my novice eye. Here's an interesting development: I cleaned the idle jets again, for the umpzillionth time, and this time it started and ran. Lumpy idle but no stalling. But.... I realized I had forgotten to snug up the idle jets, and lo and behold the passenger side jet was a hal...

Scimba - Just add fuel

Good shout but I'm cohline biohosed all round, and relatively new. I've just tested the fuel pump and it's pumping plenty of clean juice. After the last run it will now start but only run for a few seconds and only after a pump of the throttle...

Scimba - Just add fuel

Quick update. Fuel tank sender was sorted with a thinner but not-too-thin rubber seal. But the car is running terribly, again. The free fuel tank, since replaced, was a bad idea. I suspect a lot of crap has found its way into the carb. I've removed the carb lid and the float chamber was filthy. Afte...

Tiny choke circlip

Mine had a couple of rods to stand the lid on the base. Female thread on the bottom, male on the top. One of 'em has disappeared.

Thanks for the offer Mark but I got a handful from Eurocarb. Should have checked back here first.

Now, if you have a couple of the little rods inside a K&N air box....

Ignore that - they most definitely are not!
I've cleaned the idle jets and blown out the passages again (just with a can of compressed air) and all is well again.

Scim has deteriorated a bit since. I have cleaned out the idle jets a few times. Are they interchangeable? I'm concerned I might have swapped the sides by mistake...

Accelerator pump leaking?

Well... I inspected it. The gasket that surrounds the diaphragm is delaminated but that might have happened on separation. A replacement is on the way from Burtons. Since this latest problem - rough idle and stalling - only happens when the engine is hot after a run, it's a bugger to troubleshoot. O...

Accelerator pump leaking?

Correction: that's the anti-stall unit I'm talking about. So I guess it makes sense that squeezing the vacuum pipe operates the diaphragm. Perhaps a red herring then.
