Arnolt tuning specs

[Rich Slevin]

Solex's and distributor are now rebuilt and back in the car. Solex jets seem to be wrong as compared to the Arnolt book. Mine are 125 main, 190 air corrector and 47.5 pilot. Book says 135, 240 and 50 respectively. Anyone know which is correct at sea level? I have some jets coming that I need to drill out next week I though I would try a set of stock size.

Distributor was re-curved by Jeff Schlemmer who was recommended for Lucas distributors. I followed his recommendation and set the idle timing at 16 BTDC, but the low end was missing. He suggested resetting at 22BTDC, but my valves are rattling a bit. The distributor recurve seems to start advancing at about 2800 RPM and advances total of 24 degrees.

I am not sure if the carburation is the main issue or if is the distributor. But the bottom end has very poor acceleration until it gets to 2500 RPM of so. Anyone have any thoughts?

Thanks, Rich
