Ran the "low dollar 318" in the Duster today
Yeah, they crave timing.
It takes a lot of time for every molecule of gas to find a molecule of air to react with, when the pressure is that far down, and no help from the squish.
But the humor-me-adjustment was just to prove the t-port sync was off. After it's proved, you have to figure out what to do about it.
IMO there is no reason to run a lot of idle timing with a higher stall, if it messes up the t-port sync. I mean what's the point, if the engine is never pulling in that zone?I would just fix the sync, set the timing to whatever gets the sync done, then go mod the dizzy to get what you want when you need it,right? Yeah, I know those slots are hard to grind out,lol. But I hate a hesitation on tip-in,more.
But I could be wrong,too. Maybe that carb is just not a good match,or rather the primary size, for that engine.Maybe airflow in the intake is too slow. Maybe the fuel-level is a tad low.Or the water is too cold. If you had mechanical lifters I might add; maybe the lash is too tight. But I thought I saw it pretty clearly in the video.
Happy hunting.
