Refit carb

[CFarrah]

All,

I'm deep into the refit of Mercury, our 1946 Elco 47 DeLux Cruiser. We just completed 2 months of travel (2400 miles in Merc from Maine to Destin Florida...his home for the winter) with 2 kids in diapers. Was a fantastic trip, but we were plagued the whole way with carb problems.

Merc was repowered in 1953 with 2 Chrysler Imperial M45S Hemis. The engines themselves are in fantastic condition, with plenty of original spares the prior owner cannibalized from other engines. I have the original carbs on the boat, as well as 4 spares and rebuild kits. My problem is that every one of the carbs has been rebuilt so many times that the float, needles and linkages are so worn they are simply not reliable and cause bowl overflows or underpowered performance.

Has anyone refit these with new equipment, preferably 2 or 4 barrel low profile units? I appreciate your help in advance.

Best regards and Happy New Year,

Cliff

..may can help. need more info.give history on carbs.time on engines. with a carb, the trick is to cut the air flow from all the places that air should not flow. The air flow around the shaft that the throat buterfly rides on can play hell with the fuel/air mixture. in other words, the damn thing leaks at the joints! Carb kits don't often address this problem. The cure is to recarb with a new one. That's the bad news. the good news is that the recarb is not that exspencive if you look around. Carbs do just that, carburate. If you can fit the thing to your manafold, hook a fuel line to it, and put a little pressure behind it, the damn thing will run! let me know how your recarb exp. goes. yours bob miller.
