New carb installed

[Ricosan]

Hey guys,

I finally got my English Stromberg 97 carburetor and installed it yesterday. I took it out for a test drive and it sounded like it was missing on 2 or 3 cylinders.

It was running without this problem with my old carburetor so I pulled the plugs. They were black, covered in carbon. I had less than 200 miles on this set of plugs. I replaced the plugs and the engine is running good now.

Is this sound like a fuel delivery problem or an electrical problem?

If it runs good now, I would guess you had a temporary flooding problem that went away. Possibly from some contamination that got caught in the fuel valve and seat, that cleared itself out, but originally caused a very high fuel level. Just a guess.

The carb can cause a flooding condition on certain plugs,If you look on the back side of a intake!ther are runners that feed certain cyl....2&3 cyl come from one of these runners,had this problem on my 36 with 8ba,was ready to pull heads to check for stuck valves,,plugs were fouled on 2&3 ....made several checks then removed carb and desembled and cleaned including the emulsion tubes!didnt see anything but when I started up problem was gone!!!!
