Re: Ignition timing on 5.7L
Well, there's no place on the island that sells a vacuum gauge. Now I'm trying to find someone to borrow one from. In the mean time, I have a noise coming from the motor that sounds like an exhaust manifold leak without the ticking noise that accompanies it. I would think this would be a vacuum leak, but the problem is, it seems to be coming from inside the carb.
Splashed the boat and it ran fine, but the timing was still set to 10 btdc. Tried to get timing light on it to retard it, but too much sunlight and couldn't see anything. Didn't want to idle the boat any more before break in, so I ran it around the bay. Seemed to run pretty good but I think the timing is still too far advanced.
We have a volvo Penta petrol engine 3 L 4 cylinder. it's states on the rocker cover to set the timing ignition at 2 degrees after top dead centre but the engine doesn't like to run at this setting as soon as we advance it to about 7 degrees before top dead centre the engine smooth out the engine likes to run at that setting. would you say this is the correct setting or should i leave it at or am I missing out on something ?
