Ok, I'm rebuilding the carbs, cleaned one up, upon reassembly I noticed the idle orifice (jet) has different numbers & sizes, the upper carb has size 27 & 28 the lower carb has size 29 & 30. The lower carb's "jets" were moved around during cleaning so I'm not sure which number jet went where, unless I match the smaller jet on the same side as the top carb (it wasn't disassembled yet). Is it supposed to have 4 different sizes in the carb? Also I've read some people have reused their floats, is this ok? I ordered new floats & they are round shaped, my old floats don't appear bad.
