I have "learned" some things on this forum...or at least some things I'm trying to learn. Very smart people with years of experience here.
Some time back there was a "carb size" thread and now the vac advance thread.
In both of these I have read some things I'm having a hard time believing, although everything i read most certainly backs up these statements.
Here is what I'm having problems with>
1) a bigger carb increases cylinder pressure(even though it reduces throttle response?)
2) the same carb on a smaller engine needs bigger jets(even though a too big carb smokes black?)
3) a leaner mixture burns slower than a rich mixture(even though a lean mixture is more likely to ping?)
so let me apply these theories..or facts
1) my low compression 305ci will benefit from a larger carb by increasing cylinder pressure, if not why not?
2) If i pull my 850 dbl pumper off the 454 and put it on my 305 I will need to jet it up
3) my 11:1 350 has a 13:1 air/fuel ratio but pings. I can lean it out so as to allow a slower burn and prevent ping.
I am not trying to be difficult, but trying to learn by using "real" world examples. The engine is a system and must work as one. I need to fully understand this system to fully benefit from it.
