NEW OLD STOCK Float Bowl fits all PHF and PHM Dellorto carbies, which use the 2 smaller size float bowl nuts [not the later nut with 21mm spanner size]. Use with the old deep type 14mm spanner size nut or the shallow type nut that uses a 17mm spanner size. This is the plated version with the passage way that goes at an angle on the bottom as you can see.
The 2 earlier types either use a 14mm or 17mm spanner and have a smaller hole. FYI the 17mm and 21mm type uses the later type main jet holder, the 14mm type uses the earlier main jet holder....
