You're going for fuel economy, not power, ?? right..
If you're after power,, you'd be going a step back-wards .. imho
I usually take an eddy off and put one of those on,, the owners grin is always the reward..
That accel pump adjustment needs attn before use..
(PS)
Send that carb to Rusty,, let him do his magic,, you'll be real happy..
