Carb Confusion on '46 VH

Having bought a '46 single-port VH engine from Dave Owen a couple of weeks ago, it prompted me to look at the carb on my existing '46 2-port VH Red Hunter. I bought this bike in 2015 already restored and with a new carb on it. According to the Amal / Burlen book, and the Ariel parts list, for 1946: ...

Re: Filler over powder

Great information here! Every time I've considered powder coating, I've always been put off by being told (by the powder coaters) that "there is no filler that can stand the powder coating temperatures".

For Sale: 1946 NH Engine

Selling on behalf of a deceased AOMCC member's family, this 1946 NH engine. I cannot tell you much about it other than it appears to be all there and turns over. I've have had the timing cover off and the magneto sprocket and chain are there. It may not need any work...judging from the Blue Hylomar,...

However the lift ratio of the twin lobe follower is .86 whereas the lift ratio of the HS follower is .92, so on the P2 cam the twin lobe follower will lift the valve .390” but the HS fo...

Re: Strange Noise

Yes they are....yours is the one with the long splines and the boss on the inside, so quite common. I'm sure Geoff will have those.

Re: Strange Noise

As long as the splines are OK, its an easy fix and no need to dismantle primary chaincase. I always use Loctite on this nut, as well as the tab washer.

Re: Strange Noise

Simon, I had a very similar noise on '48 KG about 4 weeks ago. At the roadside, I eliminated the engine and thought at one stage it was the speedo cable, so disconnected that from the CP box which didn't make any difference. I limped home with this intermittent noise. Clearly from clutch /gearbox ar...
