Alrighty prollybwrong place for this. my name is isaac i live in brunswick ga i bought a icrbear maddog that will not start unless it gets a long full start for about 9 or ten seconds on a car i have been stranded by it twice and would like some help finding why it takes that long to start sucking gass... Once it runs u rev and hold it about 7 seconds and no more issue till u turn it off then u have to go thru that again to get it to start... Once running its verry irradic too revs going everywhere... Also it wont idle unless its idling high as almost to creeping speed then its fine

The 7 turns out means you have too much air getting in. That means either it is a very bad leak, or the stock airbox has been replaced with a more free flow air filter, without upjetting to compensate.
Had a similar problem, hard starts when cold, erratic idle etc, vacuum line was old and brittle got a crack and leaked at the intake fitting too, replaced it and pretty much everything resolved itself.
