Holly 847 or Carter BBR1 Carb?
Posted: Tue Nov 26, 2019 6:57 pm
Hello. ....So originally my 49 KB2 came with a Holly 847 Carb. I have rebuilt it, and it runs ''well enough''. I can't explain it, but I just don't like it. It has a very small constrictor in the power charge circuit, which constantly plugs with even the smallest piece of debris. I have set the float high and low, and it still insists on dying if I turn very hard, or brake suddenly. I have two micro-screens inline.. one in an electric pump near the tank ( pushing fuel = less vapor lock ) and another in the stock fuel pump on top of the sediment bulb. I took to adding a second sediment bulb (with a new unused stone in it) right off the carb itself...it provides a great visual to what the gas is doing, and any contaminants. Still, it seems such a picky little thing....it just seems ''weak''.. I have a very nice Carter BBR1 waiting in the wings...should I try it?....any opinions on which is better?
As usual, I have to defer to my old Model A, which I have had for over 30 years...When I first got it, an old timer told me to throw out the zenith and use a Tillotson instead. He was right.. I haven't touched the carb. since. It doesn't care about alcohol, water, old gas or dirt..my sediment bulb is 1/4 full and it still runs great.. (Although the main jet is the size of a pencil..)
Maybe I need professional (mental) help...!!
Thanks, and take care! Mike
