i have a 1989 mustang that was a 4cyl turned into a v8 it has a 302 with a t-5 maual its got a holley carb on it and the car dont run but maybe 5 minutes then stalls out and dont start for a few minutes im new to carbs and kinda lost with all of this any help would be appreciated

psuhillbilly150

is this occuring at idle or over any period of 5 minutes whether its idleing or your driving down the road or free reving it?

When it doesn't start, have you checked to see if it's a fuel or spark related issue?

Slow5o

it happens just at idle the car has spark so it seems to be a fuel problem but i dont know anything about carburators so im kinda lost about this weather it needs more fuel pressure or if the carb is bad or needs rebuilt

psuhillbilly150

can't hurt to rebuild the thing if its been sitting for a long time or at least clean it out with some 2+2.

If it starts to die on you have you tried clearing it out? by that I mean give it half gas let the accelerator pump put the gas in it and then floor it for a second to burn up any residual gas which may have built up. Sounds to me like it may be loading up on you. what size carb is it cfm wise?

Slow5o

its a holley 600 i have tried blowing out the carb by giving it gas but it just boggs down where can i get 2+2 at

symonds86

will it stars after it stalls if ya hold the gas to the floor while trying to start it

Gumcutter 2+2 is just a bad *** brand of carb cleaner. Did you try adjusting the choke or if its a vacume one checking the vacume levels and see if its pulling the right ammount.

sounds like it's flooding out to me

Sounds like it either loasing up or the choke isn't opening. BLack smoke???
