New Engine, No Start, Pops Out The Carb

rrs1Member

Had my stock engine rebuilt about a year and a half ago, installed and ready to start now. New cap, rotor, plugs, and wires. Pertronix Ignitor in stock distributor, checked firing order many times, and wiring is correct. The coil is good. I have 7 volts on coil pre start. The carb is brand new Holley 600. No adjustments have been made.

The engine doesn't come close to starting, it pops out the carb immediately when trying to start. After reading similar experiences, it seems like the distributor is 180 degrees out. However, the engine was run in prior to delivery. I checked anyway. With the timing pointer set at 0, the rotor is pointing at #1 cylinder. Does this guarantee that the distributor is installed correctly.

Any other ideas?

you need to find #1 TDC on compression stroke by your finger in the spark plug hole and align the rotor to the dist cap #1 tower. my guess is you're 180* off firing on the exhaust stroke

No it doesn't you have to check it is on the compression stroke i.e. both valves closed at TDC. Also the harmonic damper is rubber bonded inner to outer and over time they can separate and if so you think you have one timing set but the outer timing mark may have slipped.

Thanks for the fast reply's.

I think I understand. It's the rotating of the engine to #1 TDC that does most of the 180 degree turning, then you just turn the distributor to align the rotor to #1?

you're almost there. it takes 2 full revolutions (720*) of the crank to complete a full cycle but the cam & distributor only complete 1 revolution (360*). but yes get on #1 compression, line up the marks and set the rotor to the #1 tower. fire!

Also make sure that you use the correct rotor that seats on the breaker plate (not on the Pertronics reluctor) and does not hit the cap as it rotates.

I found that one out the hard way.........

To do fast, you can also, without changing anything else, only make a half turn with all the plug wires on the distributor cap (1 ---->6, 3 ----->5, 7----->4, 2---->8) and try again to start the engine.
