afb 1407 bog finally gone! get out the tiny drill bits. And a tuning question

When you change n/s seat, you change the float level. Nominal float level on Edel carbs is 7/16" with the factory n/seats & 5 psi fuel pressure. Change the FP &/or n/s size, & float level needs to be adjusted. Use 5 psi & increase the float level from 7/16" to 15/32" if you are using larger n/s.
Expect a rich mixture on decel because you have the highest vacuum. Forget about what the AFR meter says....
