1065 out of stock so used a 106 [the original 1065 was worn oval], raised the needle one notch and had to up the main jet to 180, then 190 when I used the less restrictive intake mesh from Hitchcocks.The original 1940s mesh now in a jar of CocaCola being purged of cack. Interesting that the needle jet on a 276 has a wider throttle range influence then on a Monobloc and can affect the main jet and influence the mix straight off idle. Didn't expect that. Carb jet block a bit worn but it's original so...
