Vacuum pump

[RAWDAWG635]

I swaped motors out in one of our trx90's, not finished yet. I put a different carb with a inline pet cock on it. Do I have to have that vacuum pump? This is the only other mini that I've seen it on. We mostly mess with 2-stroke minis.

My stock motor had it but I took it off. I had another motor built last spring which is running stock cases but an aftermartket head and cylinder and it don't have it at all. The hole in the cylinder were not there. I put all new breather hoses on it and brought all of them up to where the pump was at the battery and put filters on them

Fastdad-77, I didn't think it needed it, but i thought i would ask. ICRacing includes one with their big carb kit so thats what throwed me off. I thought (force fed) is force fed unless its fuel injected.
