Thanks for the suggestion. I checked the fuel pump push rod length in 2023 (at 139.7 mm, which I believe is within spec for the air-cooled engine - should be 139.8 mm) so I'm cautiously confident it isn't that.

Changed the ignition coil (looked very old) and the ignition amplifier for new ones from Heritage Parts Centre but no improvement. It's doing it less intermittently now - can tell it feels lumpy and jerky almost as soon as I set off down the road now... Carb rebuild ongoing when I can find the time ...

Started my much postponed rebuild tonight. I have 2 spare sets of carbs that came with the van, so hoping to salvage something decent from those

Update Changed the ignition amp for one from GSF car parts and the van didn't start at all, so will be taking that back and sourcing one from somewhere else. I'd made the assumption they are all the same, perhaps not... Took it out this morning and it was obviously down on power. No obvious misfirin...

Yeah, and I suspect the ignition amplifier is the same - being electronic, it would fail completely or work, not some weird in-between state Have thoroughly checked for air leaks, but will try the WD40 approach to double check. As I said, there is a known air-leak on the idle cut-off valve, but the ...

Checked the air filter, looks alright. Changed on last year's service, and I don't reckon there's enough dirt in there to cause a blockage

Hi all Hoping for some words of wisdom Intermittent loss of power from our '83 CU engined van. First time it did it was going 30mph ISH in 3rd. Noticed a loss of power, van started slowing down but power came back after a few miles. Van was warm and had been running for about an hour before, new fue...

Having had the headlight glass fall out a few years ago, the mirroring has now tarnished. I suspect some oily mess got onto the reflector and ruined it... I had a look on the usual websites for a replacement, and was appalled at the prices for a new one. I found a very promising wiki entry ( VW Elec...

Hi all 2.0L CU Aircooled. I'm replacing my fuel pump because its leaking petrol, and the gaskets are leaking oil. Few questions: I've seen a few posts saying to pack the pump with grease - is this right? It obviously gets splashed to some extent with engine oil (hence my oil leak) so is it necessary...

I used a bit of wire wool and very gently cleaned up the surface - mine was also covered in silicone sealant (pushrod seals likewise). Horrible mess and I dread to think how many small blobs of silicone have detached and worked their way into the engine over the years. Refitted with a cork gasket wi...

Yep did mine too recently, old seal out, repaired rust holes, filled and painted to a smooth surface, new seal (VEWIB) etc... ...rain came today and it leaks worse than ever My plan is to get some Arbomast into the body to glass seal. I'm trying to avoid taking the screen out again, so thinking of s...

Yep just follow the HT leads and adjust them in the right order - I labelled mine up when I did this to avoid confusion and rotated the engine by turning the back wheels in 4th gear.

As has already been said, you certainly can remove without taking the head off:

Hi

I'm after some info as to whether this is normal (see photo) or whether the system should be free from air. Does this suggest an air leak in the fuel line, or do I not need to worry?

Thanks
