Free Car Repair

We got a free car repair, thanks to BIL who is a mechanic. He was here during the Wesak Day and my car ngam-ngam refused to start 2 days before it. It was just 2 months ago, the same problem occurred and we spent RM755 to get it fix but I think the real problem is not fixed. :( BIL just washed the carburetor and the car can start again.
