95' YJ rebuilt engine, runs like garbage

I just replaced the tired 243 engine (with a broken piston skirt on #4) with a remanufactured engine over the weekend. Now I can't get it to run worth a darn. I can start it but the timing is "retarded" what looks to be about 15 degrees. If I move the distributor one gear over, it won't start at all. At first I thought it was missing and backfiring because the fuel had to bleed the air in the system but it doesn't seem to be smoothing out and I don't want to do any engine damage. I'm very tired at this point and I'm not sure I'm thinking 100%. Help would be appreciated. I've not found any loose wires or hoses that would not allow it to run like it has since I bought it new in 95.

Did you check the crank sensor? If it isn't in the exact right spot it will run like crap, and also check the wires to make sure they aren't pinched. Timing is controlled by the ecm so moving the distributor won't help if it was installed properly.

thanks for the suggestion, I will check the sensor location, I will also recheck the configuration of the distributor in relation to the #1 cylinder.

Where did you get the remanufactured engine? I'm looking into that also....
