Needle Suggestion...

[d_harris]

Having now put a skimmed, and gasflowed 295 with huge valves onto agatha (1098 and otherwise standard) any suggestions for carb needle? I will stick a HS4 on later to get a bit more poke but for the moment I want to stick with the standard carb but get the best needle possible in there...

An H6 needle was the "rich" needle option for the standard 1098 HS2 carb.

[d_harris]

h6 as in carb, or as in needle number?

[PSL184]

An H6 needle .

You see what I mean though... Actually, it was only ever HS6 carb wasn't it?

[PSL184]

Yes I believe so Dan...

There was an H6 carb. Fitted to the Aston Martin DB2/4, Austin Healey 100, Rolls Royce 4.5ltr, Daimler 4ltr etc

It's really not possible to fit 'huge' valves in a 295 - so I'm a bit puzzled there. That's why the 940 head is SO much better. And as the standard carb and manifold are very much the power limiting factors on a standard 1098 engine - you really won't see any significant performance improvement....... Just stick with the needle you have - set it up for idling - then do a plug check after a good run.
