don't get worried, if you need a cheap solution just visit bilal gunj, park your machine at the back end of bilal gunj... look for 4/5 good old part dealers, discuss rates, don't panic, don't show your worries, be cool, once you get overall market rates, you will become master within one hour..... otherwise don't go any where just go to Mr Adnan, the one and only Gear expert in Lahore...
the issue with your machine is minor, if it is the same you wrote....
