I installed the Mr. Gasket 925D recurve kit. Now it comes in full at 2300 RPM's so now I either need to bend a tab to make it come in abit later or install the weak stock spring (which is heavier than the new ones) on one side....
Don't know how I missed that in your last post? So are you happy with it? Is this where you're leaving it? How does it run compared to before? Have you driven it?
I drove it but I forgot to connect the vacuum advance, it seems a little more lively. I was just worried about it coming in that soon since it's still a driver more than a racecar. I just got back inside from changing one of the two springs to the lighter of the two stock ones. Now it has a base of 10 at a idle of 850 RPMs, starts to come in at 1200 RPMs, and is full in with 38 at 2800 RPMs. I have yet to test drive it like this though. Should the timing start right off of idle or should there be no activity for that first 300 RPMs? Next I might try swaping the springs from one side to the other, one tab is bent where the original heavy spring was and now the new light one is, and the other is straight where the old light one was and is now. So maybe by swapping them it may change when it starts but not necessarily when it's all in.
Since you asked I would honestly go with "at least" 14 initial. If it were my car it would be 16-18. There's no reason not to bring it in immediately off idle unless it starts pinging. You can actually lock out the timing to have full 36 degrees at idle as long as you have a way to retard it for starting the engine.
I got that one printed out. but I didn't see a part about any flat spots in the beginning... it would be nice if I could find a site that showed "ideal" curves or a list of average curves or something like that... I'm probably overthinking things.
