Oh ATVMXR, how do you do the mod on the fuel valve so it flows on both circits, I bought a new one but it still only works in reserve.

I did search all over but cant find it

You have to hog out the channel so that you're able to turn the lever to the fuel mark.

I did the mod on an old one and used a drill bit that was the same size as the channel.  Using a hand drill, i milled it out. literally took about 5 minutes.
