Hey guys, just wondering what your ignition timing sweet spot is.

36 here also... :thumbup:

36 here and it comes all in at mid 2500s. Vacuum advance locked out. (Don't just unplug the vacuum line)

Oh ya, Lock out vacume advance too ;D

You guys are great! Thanks for the quick reply :thumbup: I was too conservative on my initial setting. I'm the paranoid type. I was worried that if I had it too advanced, I wouldn't hear the engine pinging under load. I'll give 36* a try. Thank you everyone!

Drive it, advance timing, repeat over til it starts pinging them slightly go back then your done :)

X2, my timing was retarded so bad when I bought it, it would barely start. Kept twisting the dist on Elsinore until it was tits.

For those that run at lake Elsinore at 75* and 1265' elevation, the same timing at the river (~450', & 115*) MAY be too much...
I run 36-38* in the spring, but when the temps get above 100, I back it down to 34*.
From Parker (350' elev.) to Mead (1100-1150' elev.) makes a small difference, but that's where I boat.
One bad piston is all it takes to ruin your weekend :(

Wow, not one person even asked what your engine basics are. What's the motor compression, type of heads, cam, fuel.... nothing....... just 36* and run it. 36* may be right, or it could be just enough to beat your motor apart. Hearing a pinging motor in a jet boat isn't the easiest thing, not everyone's hearing is that in tune. My suggestion would be to start conservative around 30-32 and learn how to read your spark plugs. That way you're not guessing. JMHO, Greg.

Come on Greg... He didn't ask for a recommendation, he asked what is our timing set at.
You know the drill... if the customer asks for vanilla, you don't tell him how to make ice cream. ;)

Good call Greg.

So you're saying a person who's hearing that may not be as in tune as some others should jump into plug reading?
So now he'll know what plugs are supposed to look like but still won't know how to get them there.
I don't think there is a whole lot left on the table between 32 and 36 degrees in a stock to mild marine application.
Not to mention, he can clearly see what each one of us owns/drives and can probably follow accordingly...
I know I would be duplicating a big hp tune for my stock cruiser.

LMAO
You got me Omar. ;D
I should probably turn in for the night, the fridge is running low on boat sodas.
I need to get up early tomorrow and restock and then get to work on a new sprinkler line in the parkway.
God Damn The Pusher.
Carry on brother. ;)

Trying a new (to me) flavor à la Don Zig. Engine ran best with 39 degrees total, 22 of which was mechanical advance. I don’t remember the curve RPM. This time, will be trying approximately 10 degrees advance, all in by 1,000 RPM.
The Idea is that with hard blower surge up to about 2800 RPM, the timing is just bouncing all over the place. This will give it just a little retard while on the starter, then act like it is locked out.
If I don’t like it, I can always go back to mint chip.
