Quandry of the day is determining if the float level setting makes a
difference. Here's the puzzler:
I replaced one of my leaking hollow float bowl bolts (mounts the float
chamber to the carb body) with one from Moss (370-080). The new one from Moss
uses the usual two rubber grommets and one cupped washer. The bolt this
replaced corresponds to Moss part #372-190. My SU H6 Carb is from a 1960
TR3A. The
carb body number is ANC 6040.
After mounting the new bolt, I notice that the float chamber sits 3/16
inches higher relative to the carb body than it did before. Thus, several
questions arise:
1. Does changing the height of the float bowl assembly relative to the
carb affect the level of petrol in the carb jet? I posed this question to the
Moss tech guy and he says it should make no difference. Things I read online
suggest otherwise.
2. Assuming that the answer to the question above is "yes", should I
adjust the float valve tang to compensate for the now-increased level of
petrol
in the float bowl?
3. Is there a manual way to confirm the optimum setting of the float
level, say, by inspecting the level of petrol in the carb jet? If so, what's
the indicator of "optimum"?
Many thanks on this one.
