Re: petrol tank liner

I've just done that same job and after a lot of research I settled for Bill Hirsch sealant. Available from those good people at Hitchcocks for less than on Ebay. Time will tell if it works but it certainly has the best reputation and Hichcocks wouldn't stock it if it wasn't any good.

Re: Idle W/NG

A few of the shorter carb nuts have just appeared on Ebay - this is NOS but he also has used ones a bit cheaper if you view his other items:

Re: Idle W/NG

Another gotcha on pre monoblocs is that there are 2 types of jet block nut (the big one at the bottom of the mixing chamber). I see from your photo that yours is the long type. This will lower the float level compared to the other type, which is shorter from top to bottom - thus raising the float ch...

Re: Vehicle recovery for MOT exempt bikes

There was a long thread on the VMCC Forum here:
https://forum.vmcc.net/viewtopic.php?f= ... t=recovery
I think it will be viewable by non members. The gist is that, as Simon says, you are OK if your machine is MOT exempt - but some people have had bad experiences.

Re: Plating

I too prefer Doug Taylor (and will be taking some VH bits there in the next few days). In my experience they have different philosophies of plating - Doug Taylor does a lovely job but not at the expense of polishing away detail such as inscriptions so may leave a very slight pit; whereas when I took...

Re: Flexible petrol pipe

Thanks for all the helpful replies - I've now ordered 12" of the second type which will be about right for my bottom feed float chamber.

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...
