engine won't fire up? ok I have a question that might baffle a few of you. The other day I decided i would try and get some tuning done on the motor. When I went to turn it over i have nothing. I have checked everything i can think of, cleaned the points, gapped the spark plugs, checked the condenser and made sure the carburetors where working, and everything checks just fine. I even have spark, yet it still wont fire up.

Re: engine won't fire up? When did it last run.

Re: engine won't fire up? Check the compression. If you have spark and compression and it still won't run 99.9% of the time it is a fuel problem. Did you have the distributor out? Might not be back in correctly and the spark is not happening at the right time.

Re: engine won't fire up? Spark at plugs?

Re: engine won't fire up? It was running last week. It was pinging a little so i was going to advance the timing a little bit, I checked every carb and made sure fuel was being delivered and it was, and check every plug and i was getting a nice blue spark. I can't do any tuning until i get it figured out. i have yet to checked compression but the motor doesn't even have 300miles on with a fresh rebuild, so i wouldn't think that would be a problem.

Re: engine won't fire up? If it's pinging, then retarding the timing would be in order.
But, have you squirted some fuel in a carb or given it a shot or two of starting fluid, to see if it wants to run? |
Re: engine won't fire up? sorry not pinging, but was backfiring on deceleration. I have tried using staring fluid still wont go.

Re: engine won't fire up? How many carbs ?

Re: engine won't fire up? three carbs.

Re: engine won't fire up? Can you smell gas, maybe all 3 carbs are flooding.

Re: engine won't fire up? The only other thing it could be is timing. If you moved it one way, maybe move it a little the other way. Backfiring thru the exhaust means an exhaust valve is open when the plug is firing. Turn the engine over to #1 TDC pop distributor cap, look at where the rotor is pointing, probably not at #1. Get the rotor and #1 lined up and it should fire, then set your timing

Re: engine won't fire up? Could be idle adjustment screws. Closed or too much in. Try that :)

Re: engine won't fire up? I agree with brake1000,. I had a similar problem and found it was 180 degrees out. If yours was running, but rough it could still be way out.
When I got my 52 it barely ran and I found that the crank gear was out of alignment by three teeth. No one could figure how it ran at all. Could be you snapped a tooth??? |
Re: engine won't fire up? A very fine mechanic always told me, "as long as we are having a conversation about an engine NOT running, it takes TWO things for an engine to run, GAS & SPARK!" SO.....if you have spark???

You need to get back to basics and confirm the dist is in the correct position.Your statements sound like it wasn't correct from the time you installed it from the get go.At true TDC on #1 cyl. Appears a tooth out.Running it for 300 miles with the problem described isn't the best condition for a new engine.
Here is the wiring |

Is it really backfiring? To me, a backfire sounds like firing a large caliber gun, loud enough to wake the neighborhood, strong enough to explode a muffler case. Crackling on deceleration indicates a lean condition at the idle mixture. As for the immediate problem, I'd suspect you flooded it. Try cranking with the throttle floored. Try a spray of starting fluid down the carb. |
Re: engine won't fire up? Sounds like a broken cam gear.
