Have a rough house 50 and I have a 70cc pollini kit and NYC racing transmission set up. I'm ordering a 19mm malossi carb and I know I need 5mm jets for it but when i look online there are two sets 88-110 or 70-92 and dont know which ones to order. Can someone help me with this....
I'm going to take a guess at this, but a Buddy 125 and 150 use a #92 stock so I would think with a 70cc engine you'd want the smaller set of the two: 70-92. Those more knowledgeable with the Roughhouse are welcome to pummel me if I'm wrong.
Go big. Stock jetting on the roughhouse is 82, and you have to go to mid 90s with a top end kit. You'll also want to swap your idle jet from a 35 to a 40.
