To test his theory, see if you could borrow a friend's Karizma TPS and fit it on yours. If that works, then you'll have the solution.

Another way to check would be to use an ignition timing light and check whether the ignition advance is working correctly. For this, the mechanic must have the right tools and knowledge. Visit a good mechanic or write to HH complaining about the problem so that they help.
