I drilled and removed the stock needles, installed the adjusters. Going to install a
"D" plate, running Solas prop "13/19. All else
stock except intake grate.

What should the carbs be? Still using stock needle/seat and spring.

I checked the past post, but no definate on the carb settings.

Thanks Charles
