Hi, which idle sounds better? First or second?

First after getting boat:





Then after syncing carbs and fudging with timing etc..




Haven't set idle timing, haven't made it to water yet.. Second is smooth but is it better? Excuse quality..

Thanks

Hmmm. Setting up an engine on Muffs is never ideal. You really need to have the leg in water to the normal depth to get correct exhaust backpressure.

Both seem ok to me although second does sound better in theory.

Gonna stick my neck out here, IMO the first one sounds better, it's a 3 pot, it should sound slightly "rough" as opposed to the smooth (but too fast) idle in the second video.

Cranking timing is 28 and Max 23 at 5500.. Like I mentioned haven't been on water to set idle timing..

There is no idle timing spec on my motor in the manual - all the 60 3 cyl figures are blank.. so i guess you set the idle by rpm in the water in gear?

Also - I got tdc using the piston stop method yesterday and cut a hole in flywheel cover - couldnt find a timing pointer anywhere.. so made my own permanent mark and used that..

Bit windy today but will see if i can get to the water -
