Hard first start of the day

[CRF250Xrider]

Hi guys, im new here. i just got my first mercedes 300sd 1984, i really had a urge for a diesel, and a friend gave me his when i asked if he would sell it,
this mercedes is soo beat to hell, i think it would win the contest of most screwed up 300sd. anyways

The first start is impossible without cheating with a very small squirt of ether... i know its bad... but after it starts it will start super easy everytime after.
im in san diego CA , soo its not cold...

just wondering why the first start is impossible. is it ether addiction? i think the glow plugs arent working.
