Issues with evinrude v8 carburetors fuel delivery

[alexvzx]

I am looking to purchase 85d. I do some search and do not find any of them available. Maybe any of you can point of one dealer that could sell me a set.

Why do you want to go 5 above stock? They never made a 85D, production stopped at 83D although a few larger sizes were available thru second effort.

[alexvzx]

It was recommended due to the compression and the setup.

[racer]

Did you cut the heads? What is the set up including boat and prop? The 86/7 have high compression stock. Have you checked timing on all 8?

[alexvzx]

Compression is from 150 to 160 around cylinders. Prop is a raker 26x14.5. All cylinder has spark (blue). Pistons are wiseco and if we're etched correctly were installed as per manual.

They came with 150 psi stock when new so if no port work it should need no more than 81D but should be fine with the original 80D so long as they are factory and not drilled. IMO I would indicate flywheel and check timing on all cylinders.
