Let me hunt through my pile. I’ve got several sets of wmv but don’t know what number. I always thought they had to have a bigger opening. Thanks

In my personal experience with .modified 2.5s and making power along with rpm the wmv 18s wasn't even close to the wh46 or wh20s. I took 46s off and immediately put wmv 18s on , got it jetted , the idle was cleaner and gas milage was a ton better but that was it in my trial run , and I think we can agree that gas milage and HP dont belong in same sentence on these old 2 strokes. I didn't waste any time putting the 46s back on , and when I went from 46s to the 20s I have on now, I seem to lost little hole shot but was better everywhere else , now that I've had time to experiment with jets, it's tuned now it has good idle, great hole shot and great mid-wot. I've got another guy that I talked into tryin 46s and he took wmv18s off and said he wont go back either. To each his own , that's why we try things. What works for me may not for you visa versa. My motor was originally a 240 sport jet ( 225 promax) ported ,compression etc etc. I have 86 mains and 60 idles in now and it leaves out hole like efi turning 28 chopper on bass boat to 7k
