I've owned twin engine Chris Craft, with OEM engines (chev 283) and OEM
carbs.

Rebuilt both and never noticed any difference between them and the carbs
I've seen on those engine in cars. I know the rebuild kits were the same,
including the jets, float level gage, etc.

I don't mean to be argumentative, but I'm still wondering what other
difference there is..
