Alky at idle

[Don W.]

I discovered that if I "test" pump a little alky at idle the engine went rough, of course, but then idled smother than before. Has anyone seen this? I wonder if the alky cleaned the IAC circuit in the TB?

I haven't "tested" again since I'm installing a Walbro and don't intend to test much anymore because of potential cly wash down issues but...Just wondering if anyone else had seen this.

Re: Alky at idle

i prime mine all the time, mainly to cool the intake down a bit and make sure the pump is primed for the strip.
i once ran the engine on the alky cause my fuel pump didnt work, had to drive it back from the end of the strip to the pits, holding the primer the engine ran enought to drive it back on 100% meth. got back and the intake had a layer of ice on it. had not ill effects tho.

it probably just richened up the mixture which smoothed out the idle. That is what it does on my truck.

Re: Alky at idle

Are you running alky or meth?

Holding the prime down to long will make the truck go super rich and will make it stumble. Same if you ease into it about half boost and stay there while not making the truck really go any faster. (At least mine does..) Its probably running smoother cause its cleaning everything after you primed it.
