The test in question was going uphill, so under max load.
5.67 axle ratio, so not doing 68 mph in second on a 3 speed box!
Float chamber is vertical.
Blue spring fitted.
Damper oil is 3 in 1, so pretty thin, but thicker oils always seem to give so much resistance in winter temperatures - any thoughts on this being contributory?
Hello Bob,
68 mph was assuming a change to top gear!
More sensibly can I ask what needle you have in your 1.25 SU. I have the same carb on my special with a blue spring and no 6 needle. A little rich but goes extremely well.
