Ive heard that if your running reeds that the four stroke atomizer is the one?

Nah, use 2-stroke. Especially if you have a higher performance engine with a good pipe.

Or ditch the PHBG for something better :/

It would be a whole lot easier to tune.

so what exactly is better than a phbg carburetor? I have a 19mm phbg carb on my moped. Someone mentioned a mikuni upgrade or phba but noone ever mentioned in these blogs how to modify them for moped use.

There is nothing wrong with a phbg carb. It's just harder to tune because of different needles, pilot jet, main jet, starter jet, atomizers and slides. You have to have the correct one of each in your carb for it to perform correctly with your setup. Other carbs require playing with half of that which makes it easier/better.....

There are some other aspects that are also detrimental for PHBG - no main air correction jets, too-small needle tip diameters compared the main jets they run in mopeds, maybe more.

Mikuni VM is pretty similar to PHBG, but always has seemed easier to get running pretty well in my highly anecdotal experience.
