if it fits horizontally parallel with the carb body right side up or upside down it would probably be ok no ?
in any event if OEM floats are not available …. Chineese ones are probably the only option or fixing up the old one .
Carbman Carb Repair Kit w/Float 2hp/3hp/4hp for Johnson/Evinrude 398532 Sierra 18-7043 : Amazon.ca: Sports & Outdoors
not a big problem to solve.
or….. 3 kits for 34$ …incl floats !!!
Actually it is kind of a big deal. I’ve tried over 15 and I don’t want to keep buying and hoping that one will fit, so no short answer is there aren’t Chinese ones readily available that work. I’ll try and get ahold of Arthur,
