High idle during Offroad activities

[birddog321]

I took the fam out on an excursion this afternoon and noticed that my B2 starts to idle at around 2500-3000 RPM(No Tach)as soon as I hit the dirt. But if I restart the engine it runs normally until I hit a rough spot. This isn't the first time I've noticed this and was wondering if anyone else has encountered this.

That seems bit odd. Vacuum leak? How's your IAC?

Mine engine is carbed, so i don't think i have IAC

Probably due to fuel slosh in the bowl...splashes out and down the throat of the carb. If you sit still for a few minutes does it go away again?
