ok...just got my car motor back together....i turn it over and it turns over but then backfires.....i pulled the #1 spark plug twice and turned the crank until the #1 cylinder is at top.....i turned the key just enough to get it to turn over then i checked under the dist cap and the rotor was in different positions so i moved the wires around to make the #1 wire where the rotor was and put them in firing order after that....please help....
