hello, I have a walbro carb with # hdb-6b. The bolt pattern is the same as the one I have on my hommie33 mounted on a Bridi old timer. The one on the hommie has a #28 on the throat.I went into walbro& they only have the specs for a hda carb. Does anybody now about this carb. thanks

Originally used on a McCulloch
15.88 mm venturi
Diaphragm rebuild kit D10-HDB, retail $4.56..Complete rebuild kit, K10-HDB,7.37
New price, $54.00

Hi,
15.88mm is way to big for the 33cc Homelite. A 12.7mm would be a much better choice, as it comes with a 11mm(28/64ths) carb.
