thanks @hayzin @Dee Dee @celica for the wishes
Akif bhai, our mechanic made sure that the block and internals were in perfect condition.
Carburetor was up next and all the discussions of PW regarding the ever troublesome carbs of 2f and 3f were on back of our minds. The carb was dismantled and on inspection one of the butterflies was stuck and other had quite a lot of play. So the butterfly assembly went to the expert in Sutan da khooo. The old gentlemen did take some 2 odd days for fixing it but did a great job.
Having luck on our side, we got a Japanese 3F car rebuilt kit from Aamir bhai, the rebuilt kit was instrumental in getting the carb back to work. Thanks to ALLAH, the carb is working perfectly without any missing.
However, given the reputation of 3f carbs, there is always a "Weham" that its going to start missing anytime
Sorry I didnt take pics of the carb rebuilt
