help me start my burb! Please :D

[jumbo]

Picked up my 89 burb this weekend from the 2nd shop that's had it (it's actually a new one, the one i bought done for $4500 was too far gone and got scrapped) but it was not close to being done. I was supposed to pick it up in April completely done, i picked it up 9 months later and he fabbed half the floor and almost all the dash mounts when we got there

Anyway, he said it ran before but blew out the freeze plug and now it won't start. It cranks fine, but won't even try to catch. It's getting gas, timing seems ok, what else could it be?
