Well, I took the carburator apart totally and put it back together with lube n stuff, and still, there is no suction. I think id wrather get a new engine beacuse i will be sure it will run. I dont even know the source of the problem. Engine suggestions?? os .21 rz is the engine im focusing on or a nova rossi. Im probably going to get one off ebay beacuse of the huge price difference. Thanks!!
