[QUOTE="Chris Launders, post: 104811, member: 2010"] As regards Mk1s and float levels I had an instance last year of fuel starvation, I had the float level set with the float level .080 (2mm) below the face of the float bowl and a brass needle with Viton tip, so I couldn't understand what was happening as I had a good flow to the carb, I called Amal and was informed that with modern fuel the float should now be set level with the top of the float bowl and they have found that unless the float actually lifts the needle the brass one is too heavy to be lifted by the petrol pressure alone so now recommend an alloy needle with Viton tip. The latter was the problem I had, the float was hitting part of the float bowl before lifting the needle but was taking pressure off it so some fuel was getting through, enough for steady riding but anything over 60mph and it was being starved.
