:::Stumbles through the finish line hitting the ground breathing manically:::
I can't believe I made it through this novel of a thread whoo.. I'm getting my new Grubee Super rat 66cc tomorrow and I'm seriously considering running 100:1 from the beginning. A couple posts back someone mentioned getting a smaller carb jet. Does anyone else think this is necessary?
You won't regret it. It burns clean and doesn't smoke. You may find with the low oil content in your fuel and thus lower viscosity you may need to go to a smaller main carb jet and lower the needle with the clip in the top groove. I am running a 66 jet in mine. You might try a 68 first. Sick Bike Parts has jets. The stock jet is a 70 (.7mm).
