Question : Hard starting problem

[perfimage]

93 Z34 150k miles runs perfect once started, no miss, no smoke, smoothe idle smooth power, but can be a bear to start when cold/damp, particularly after sitting a couple days, like over the weekend.

It kicks and bucks and backfires out the intake, will eventually start, acting alot like flooded carbureted engine, though no raw gasoline smell.

If i start it every day and let it warm up, there is no problem.

Any ideas?

my 92 euro 3.4 is doing the same thing right now.
