Price point on a saw with the old metal toggle switch is a little disappointing? But that might change.
I was heavily into cars in my 20s mostly carburetored hot rods and muscle cars.
I worked on alot of carburetor repair and maintenance, anything from 1936 single pot to variable venturi predator carbs.
Most of the time it was simple maintenance and over haul of gaskets but in the event someone else was in the carb that could be different. I have done 1000s of carbs.
The Carter AFB 4 barrel was on of my favorite, 1964 Pontiac had an excellent model, Edelbrock bought Carter's design from Weber and then resold new models based on the older design.
There will always be knock offs of quality craftsmanship, some saying about the highest form of praise.....
But I stand by my knowledge of a" fool and his money being separated", milled metering blocks, shaved throttle plates , and ported jets were all language for loss of money and a ruined carburetor. The machinists who did this kind of work still took their time and used quality tools but non the less ruined a perfectly good carb.
Early 90s I got stonewalled several times by Edelbrock on casting flaws in the 1400 series carburetor not because they didn't care but because no one at the company could do anything about it, they out sourced all the work over seas and they couldn't do anything about it. They sure as heck didn't mind getting good money for them though.
Drilling Chinese rotors do not make them Porsche rotors even if you have the best machinery in house.
