Triple R thank you for the great write up.
Also further research on the 1405 and 1406 has found they are different carburetors beyond metering jets and rods.

Billbo does a great write up
At this stage it is between the 1405 and 1806. Especially since they are all real close in price that will not be a variable. And I dont think 50 CFMs will be much of a difference
