Hello

I have tried to get this engine to run nicely,

When you put the car on the track the engine bogs out when you try put too much gas, tried all sorts of tuning ?

Would you think this issue is a bearing related or dodgy Carb ??

The chap i bought the engine from said it was good , but i had no luck today

I have heard these engines suffer from Carb issues

Any advise would be welcome
