Rough start up occasional backfire

[Bullys_special]

Hi Guys, this is my first post I have had my 1991 E30 320 Cabrio for about 2 years now. It has covered 136000 miles. For the last say 6 months it has been hard to start, takes alot of turning over it will often give a little fire up then die and occasionally it will backfire during turn over. Once started apart from a tiny bit of tappety noise it purrs quite nicely. This starting issue is getting worse now due to winter comming in. It was serviced at my local garage last month so plugs have been changed. Does anyone have any ideas what I may need to do to fix this problem?

sounds similar to mine. 320i cab, recently serviced etc etc, see thread chitty chity bang bang for answers. reckon it could be damp.

Were the leads changed?

or was this changed during the service??

dont think leads or dizzy were changed, can I just take the dizzy off and dry it up a bit. Should I change the leads too? Sorry i am an amature.
