Hi, its me again.
Thanks to all those who viewed my query. Anyways i was able to solve the rattling sound that my car was experiencing. I 've search and read somewhat similar to my problem and lo, i hit the answer. The rattling sound was produced because my car timing was off. I tinkered with it last weekend and did the following: Adjusted the air+fuel mixture, carburetor idling and the timing in the distributor cap. I tested my car and the rattling sound was gone. It was so nice not to hear that rattling sound again. No need to go to a mechanic. Anyways, i just want to share my experience with it. Btw, internet forums are great!
