Rebuilding Tri Power- Have a question on jets

[Bob H.]

I'm sending my carbs out to be rebuilt. Since we dropped the compression down to 10:1, should we drop the jets down from 66's?

It just seemed to be running pretty rich since rebuilt. Any ideas are appreciated.

Bob -

The center carb jets on a 427/435 should be #64.

I would consult your rebuilder and get his feelings on the situation.
