I have bolan with same problem. These engines came with mechanical pump connected with Cam Shaft. When you start it takes a little time to get fuel from tank and then deliver to carb. This problem increases if you are in winter. The engine oil is thick which presents additional load on your starter motor. When starting car in winter always start it with clutch pressed, no extra load on alternator (blower etc). Get your fuel pump checked. Lastly get its carburator tuned.

thnx bro,
well.. the fuel comes properly in carburator.
we took it to few USTAAD's
1st ustaad tuned the carburator, but no result
2nd ustaad did some modifications with fuel pump and some other things, but no result

i think that what if we replace the carburator? will this solve the problem?
