Hi Guys, thank you for all the replies. Its been a while since i opened this thread and the mini stil remains in the garage.
The problem with changing the gears is now fixed! I bought one new governor and had replaced it. But now i have another issue.
When the mini reaches 4th gear, the rpm increases like if the clutch its over, but there is nothing wrong with it. The clutch is ok, and everything else is checked.
Does anyone knows whats going on, or had the same problem as me?
Thank u (my english is kinda rusty, feel free to correct me)
