Hey guys, i recently put togheter my engine after replacing the intake manifold gaskets.
Now when im trying to fire the engine, it only backfires, from the engine and not from the exhaust :O The cylinders got flooded when i was removing the intake manifold, i only unscrewed it and checked that i was loose and called it the day, not smart.
Ive crancked the engine without spark plugs to drain the cylinders.

I did manage to twist the return line from the distributor when i removed it, but it still flows, i will replace it, but i hope to get the engine running before all of this

Any help would be much appreciated.
