Flexible petrol pipe

I am about to source the petrol pipe for my 1939 Red Hunter. I know that it should be "flexible" rather than copper pipe but all the illustrations I can find don't show it very clearly. Basically I can source braided metal covered pipe like this https://www.ebay.co.uk/itm/Petroflex-Braided...

Re: valve springs too strong?

Just to tie things up a bit, I have refitted the rocker boxes yet again and using 4th gear the engine turns over smoothly. I am amazed how much of a difference using 4th instead of 2nd makes - you live and learn! The valve lifter needs some attention as it did lift the valve a bit but then slipped o...

Re: valve springs too strong?

I have tried turning the rear wheel in second gear with the plug out and it does go over with a lot of effort. I am a big bloke and find Panthers and Venoms easy to kick over. The valves go up and down as they should and the clearances can be set ok. I'm sure the cam is timed correctly. My main worr...

Re: valve springs too strong?

Hi Alan I didn't have any old ones - the bike was not complete - and also I didn't measure them, just fitted them (along with new spring washers, collets and valve caps etc.). It was hard to tell the strength from fitting them as I have a big valve spring compressor with loads of leverage so they se...

Re: valve springs too strong?

Hi Alan

thanks for the prompt reply - I got them from John Budgen about 4 weeks ago. They were supplied as correct for a VH - both the club and Drags were out of stock I believe.

Cheers
Brian

valve springs too strong?

I am fitting the rocker covers on to my 1939 VH Red Hunter rebuild and I am wondering if the valve springs I have are too strong (there are a few references to this in previous threads I turned up by doing a search). When both the rocker covers are tightened down it is very difficult to turn the eng...

Re: 500cc valve collets

If Vincent's don't suit then John Budgen has them.

Re: ‘38 Red Hunter on ebay

As I'm currently restoring a 1938 (1939 model) VH Red Hunter, I would be very interested in more analysis from the cognoscenti on this bike. As far as I can tell it looks very correct but I'm not sure whether the oil gauge and damper knob are post war. I'm very much an Ariel novice and I like to get...

Re: Chrono speedo repair

The link actually goes to the site of David and Philip Woods. David has just refurbished the Chronometric speedo for my Red Hunter at a very fair price and a very fast turnaround. As a bonus he has recalibrated it so it will read correctly with the PA ratio gears thus saving me either changing the l...

Re: gear case cover uncertainty

Hi Paul,
thanks for the reassurance, I will blank it off until one turns up as none of the usual sourcers seem to have any.
