One more break in question

Honestly, I never noticed much of a difference in performance after break-in. But then again, I have never really used an odometer or a speedo.

That's strange because with a 32T sprocket, you should get at least 30mph on a flat grade. Last I calculated, I got a max of 32 mph on a flat road with my 66cc engine with the 44T sprocket. I've never used a smaller sprocket, but supposedly the smaller you go the more speed you'll get but less uphill power.

What mixture are you using for your break-in period? If you're using a 16:1 mix like the chinese instructions say, try instead using a 24:1 mix. Oil in the western world is of better quality so 16:1 is a lot of oil to use. Won't hurt to use 16:1, but you'll get both an greasy engine and a slight decrease in power.

whoa that too rich. you should break in with 24:1 and later run 32:1 which is way sufficient. You have too much oil.

I feel that 16:1 is also too much oil. What does your plug look like. Before I found forums I too did the same on my first build. With each additional, build I started with 24:1 and on to 50:1. Using Amsoil.

I checked my plugs the other day and it was clean, little grey( from lead lol). But other then that it's all good.

You want it tan, so a little less oil might do the trick.
