Tiny choke circlip

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....

I walked into that one. I think it pinged off the other way but I'll definitely check...

Does anyone have a spare circlip for the choke linkage on a Weber 38 DGAS? Or a tip on where to find one please...

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.

Accelerator pump leaking?

Gurus, I'm still chasing rough running issues on my 5a. Last step was to clean the idle jets and blow some air through the carb. Went out for a spin today and only just made it home. Really rough idle, hunting, and eventually dying. I let the engine cool and fired it up again and it idled roughly wi...

Scimba - Just add fuel

After a few days of trouble free motoring the tank has started seeping again, around the sender. I've got my trusty garage to have a look at it and they reckon the home-made seal is too thin. I gave them the original that Walkers provided and they say that's too thick, and I agree. There's no way of...

Thanks Jim. I owe you one, or ten - not sure of the current tally. Cleaning out the idle jets and blowing some air into their recesses has got my Scim running. A bit lumpy but I'll go over the jets and fuel filters again soon to be sure.

Post-lay-up blues

Finally found time to bring the Scim out of hibernation. Charged up the battery and fired him up. It starts but the moment it comes off the fast idle it dies. Spark is good, and I can't find any air leaks. Car was running well when I garaged him in December. My suspicion is that the fuel tank proble...

Scimba - Just add fuel

Thanks Chris. I got hold of some 1.5mm nitrile rubber sheet and made my own gasket. Finally the locking ring will start into its groove. I've tapped it round as far as it'll go with a drift. Is it meant to go all the way round so the tabs rest against the next detent? It didn't go that far before th...

Scimba - Just add fuel

Thanks Roger. That certainly helps but the whole assembly would still need to compress a lot more to get the locking ring started. I've lubricated the seal to allow it to stretch under compression and I've adapted a piece of pipe to allow me to apply most of my 200+lbs of weight onto it, but to no a...

Sadly the old leaky tank has the sender held on by a plate over six studs with a cork gasket behind it.
