so lets say i have the engine in the competition prep manual, and i'm starting with a 48 weber, jetted like they have in the comp manual, which uses a 42mm venturi.
if i go to a 38mm venturi, which is 20% smaller, does it run richer? 20% richer? i'm thinking 38mm might be good for break in, and smogging the thing |

With a 36MM choke I run a 210 main 80 air F-7 tube. There is a lot of stuff to change for road racing. Not much on the street. Lynn E. Hanover |
think a PP engine will pass smog on alcohol?
