85hp Upgrade Carb & Prop Question

[Ragwing nut]

I don't know if the 85 marvel had accelerator pump in it. I also don't know what altitude you operate at. You can modify your stromberg to 85 config with venturi and jet swap.

Well my engine is giving me fits, so while I am at it, I am thinking it might be time to pursue the c85 upgrade. I am fortunate in that the STC was already purchased by a previous owner, just never installed. I am looking at an 85-8 on a short mount to keep it certified non-electrical and weight down.. As I will need a carb, is it worth upgrading to the Marvel vs tracking down a Stromberg? (I have a strombuerg on my a65 currently.) Also is it worth installing a mixture control?

Lastly any climb prop recommendations as my 7442 isn't going to cut it. I am just trying to get an idea of what to look for to start and then can dial it in.

I have tried to read through all the old archives on here regarding the upgrade but still have a few holes I am trying to fill in. Thanks in advance.
