Dellorto floats
Posted: 25 Aug 2020 10:49
I appreciate this is a touch esoteric but it might help someone in need a replacement for a punctured float, as I did recently.
The float part number on our VHB 25BS floats is 7450.2, the floats are black, and adjustable for fuel level. An alternative white version is available but are unadjustable for fuel level. There are three variants of the black floats 4570.1, 4570.2 and 4570.3, differentiated by weight. The 7450.2 is 14 grams.
Eurocarb's website show that 4570.2 black is now unavailable but the white ones are, with the same three part numbers. Trouble is - and what worried me - is that the white 4570.2 is only 12.5 grams, so - I thought - would reduce the fuel level resulting in a weaker mixture. Knowing how important float height is the these carbs, I contacted Eurocarbs who assured me that, although the white ones were lighter they have the same buoyancy, so there should be no effect on float level. Well, that's all tright, then.
Not many people know that.
