Is there a reason for the exhaust extended below and behind the leading edge? Perhaps to avoid any chance of fumes in the cockpit?

Although my engine is running quite happily I shall remake the ignition leads as the terminations and boots I've used occupy space a little inconveniently. In particular the leads from the coils to the lower plugs cross over beneath the engine just where I need access to the Curtis Valve I've instal...

Hi Ross, There is an LAA mandatory to replace or crack test the wing bolts. Bolts of that length are like rocking horse ordure (they are imperial 5/16 if I remember correctly - which is very close to 8mm, hence any metric confusion). Because of the difficulty of getting this length Nipper aircraft h...

Any sailing supply shop should be able to sell bungee by the metre, choose the diameter you want, cut to length and make up your own ends.

Yes Paul, the hangar behind is the old GSA hangar, now used for renting out at humongous costs by Bicester Heritage for events. I peeked in once when it was being prepared for a wedding and it had a full size old style merry go round down one end and catering for ~ 150 in the main part, plus a bands...

At last !!! After much midnight oil on the mechanical installation: Quite a lot of work to get the Leburg system sparking: And a nightmare sorting out the fuel system - including removing a leaking Curtis drain valve that appears to have had locktite as a seal :shock: The first run of the modified V...

Hi all,

In a box of goodies which came with some VW engines I received recently came this dual mag.
Anybody know anything about it, what it was used for etc? It's probably not much good for a Nipper as it would stick through the firewall quite a bit.

Jim

That looks just the job and it's cheaper than the rebuild kits. I may just invest in one for the spares box.
A combination of rotating the top and replacing the brass fittings with angled ones as necessary would surely make the fuel pipery work fine.

Some progress on the SEV pump. I emailed a photo of the pump to VW Heritage and they sent me what they thought would be the service kit, unfortunately it turned out to be completely unsuitable. This is probably because they were working on the age of the engine and the assumption it was in a vehicle...

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...

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...

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...

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...

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.

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...
