318 No Start Backfiring Through Carb

Hey all! I bought a 1985 Dodge D150 about a year ago as my very first vehicle. It would stall and felt real ‘heavy’ and after growing tired of paying mechanics that would attempt to fix the issue but would ultimately, not, I decided to take matters into my own hands. Despite never working on an engine before, I just finished up a complete overhaul on the 318. Heads went in for a prep and valve job, block was also ‘prepped’. (Not gonna lie, I have no clue what a ‘prep’ job entails.) It was also bored 0.030in. After getting the engine assembled and popping it back into the truck, it won’t start. It cranks, but after a few seconds of cranking, a mist of fuel/smoke would blow out of the carb. I’ve set the engine at TDC and plugged the wires in accordingly to get the timing correct but no luck. What could I be overlooking?


It sounds like the distributor is 180° off...

Remove the distributor cap and the #1 spark plug... Watch the rotor in the distributor while cranking it over with your finger over the #1 spark plug hole... When you feel the pressure on your finger, that's the compression stroke and the distributor rotor should be pointing to the #1 spark plug wire on the distributor...

If it's 180° off, the distribotor rotor will be pointing to the opposite side of the distributor... Lift the distributor out of it's hole a little and rotate the shaft 180° and tighten...

When starting a new engine for the first time, set the timing to 10° advanced (BTDC)... Put the engine at TDC and rotate it a little more to get the timing mark on the harmonic balancer to line up with the 10° line on the timing chain cover, then rotate distributor base so the rotor lines up with the #1 spark plug wire on the distributor cap...
