Re: VW exhaust scheme

Good Evening Dave, Thanks for that picture which is surely worth a thousand words! I have concluded that the top fixings should be flush with the top edge of the firewall and that the Nipper drawing I have is in error. It would look rather strange for the top of the cowling to stick up 10mm from the...

Re: VW exhaust scheme

Thanks David, that looks like a good starting point to copy. I like the hot air pickup inside the cowling. I have a secondary problem with my existing set in that the port forward lower spark plug points directly at the port fwd exhaust pipe and the right angle plug cap and ignition cable are very c...

VW exhaust scheme

Has anybody got any photos of their exhaust installation - cowlings off - that they could share? My Nipper has the 4 downward open pipes arrangement but they are crudely made of mild steel and won't last for long. I'd like to fit a system made in stainless and a silenced arrangement wouldn't go amis...

Re: Nipper firewall

I've come up against a head-scratching moment in my firewall replacement, best illustrated by the attached pictures: 1. The clip from a Mk3 drawing shows all the attachment points for the cowling to be protruding from the firewall, this would result in the aft lip of the top cowling sitting with a g...

Re: SEV Fuel Pump, service or replace

The only information I have is that one of the answers to my enquiries was that it was used on a post war Morris van.

Re: SEV Fuel Pump, service or replace

I think you'll find that getting a service kit for that carburettor will be challenging. I've tried many specialists, including the manufacturer, and the usual response I've had was 'haven't seen one of them for years!'. By good fortune I was wandering around the flea market on the last day of the r...

Re: SEV Fuel Pump, service or replace

Word of caution here; I believe some after market pumps have plastic parts substituted for metal bits in the original. I picked this up from one of the engineering forums (fora?), These may be unsuitable, I can't remember why. I have the same engine so will be looking for a service kit or replacemen...

spark plugs

Good Morning, tapping into the font of all knowledge again :) My engine is a Rollason Ardem, originally 1500 but now 1834, ignition is twin Leburg. The data I have is rather old and calls out Champion L T or Lodge H N plugs. these are old designations and when I look up the current alternatives they...

Re: original Nipper brake system

I am currently in the process of changing from my original wheels to 4x400 to get better availability of tyres. My concern is getting caught away from home with a u/s tyre and no spare - I've been quoted £400+ for new old stock. I'm sure you can probably get them cheaper, they used to be common on p...

Re: Nipper firewall

Good Evening Paul, This could get a little tricky with the ply patterns and hand bashing but at least the base material is cheap enough. I've managed to elevate myself to a sufficient level of competence with CAD to be able to draw up parts to print out full size and compare against the original. I'...

Re: Nipper firewall

Thanks Paul, I've reverse engineered my firewall to create a drawing which I believe is pretty well correct. I am going to print it out full size (A1 at the local print shop) and photo-mount it onto the new material. That should get all the fixing holes in the right place. Then I'll sandwich it betw...

Nipper firewall

Good Evening All, Anybody got a copy of a drawing of the firewall? Preferably dimensioned and scanned or in electronic format? I've just abandoned trying to repair the one on my Nipper and bought some 0.5mm steel sheet to make a new one. It will be easier than all the patching up required on an alre...

Re: Zentih carburettor - service or replace?

Good Morning Paul, I think I'll gather information about the Stromberg alternative via this and the LAA website and also Engineering. The information I have so far is that the CD150 is fine for the 1835 although the jets need changing. There must be many examples of this engine with the CD150 flying...
