Throttle Response Q?

[Stalkaholic]

Is there a difference between a "bog" and a "hesitation" and if so, what is the difference?

A hesitation is a delay in throttle response and a bog is when u mash it falls on it face and u back off the throttle trying to make it better!!!!!:hmm

That's hard to say, but I know a bog when I hear it and feel it. I know it's not a hesitation.:rolleyes:;)

to me, a "hesitation" occurs when the engine runs up to a certain rpm, hesitates at that rpm, then begins to climb again. on the other hand, a bog occurs when the engine accelerates to an rpm, then falls back to idle or slower, making the driver feel like he has to pump the throttle before it will take off again.
i fought both of these conditions for a couple years, finally reading every book i could get my hands on, and talked to the head engineer at BG about what was happening before i finally got things to work consistently. generally, it's a lean condition somewhere between idle and/or intermediate circuit, before rpm allows a full transition to the hi-speed circuit. i fought the conditions for 2 years, while 2 other guys i knew were running the exact same carbs, and never experienced problem 1. occasionally, i'll still see it, like in san diego last year when the air was ridiculous, and everybody was fighting the same thing.
most people "feel" something like a bog, and it "feels" like your idling, and the thing just goes to less rpm than idle. but, expanding a datafile always shows that the engine revs up a bit, like over a tenth to two tenths of a second, before falling down. knowing the rpm can help in determining what action to take to resolve it.
