The only thing I will add to this is that you might try to find a 54 235 carb. That 216 carb is a tad small and all of the calibrations and jetting, from the idle circuit, through off idle, to wot, are all engineered for use in the smaller motor. On a 235, if I am using 216 carbs, I am using them in a dual set up because the 235 dual carb set ups tend to run a little better with two smaller 216 carbs. So to get your motor running it’s absolute best, find a carb that it was meant to run on. I think you will be better off in the long run.
