very true!!!!! also alot of guys seem to want to give throttle when on lid waiting for marshall to flip back over, same thing happens here, stay off throttle and will stay running (if clunk is working right) as soon as you give a crap ton of throttle it is bound to suck air, less throttle the better

something else to keep in mind..... if your pit guy fills your tank to the very top, when he snaps the lid back down, it can actually "push" fuel thru your line, and flood your carb, causing a flameout... This explains flameouts that occur before you leave pit lane, however, if your car dies by the time you reach the end of pit lane, or shortly thereafter, it is due to reving while the lid is open....

Well part of that comes from people trying to get the attention of a marshal by using their "nitro horn". Which I'll admit is necessary sometimes. Not that its good for your engine anyway. I'll say if a marshal is on their way to your car, and you're engine is tuned properly, you shouldn't need any throttle.

a air filter , which im learning now not to oil the outside of the outerfilter just the inside or have it dry.
not during my pit stop, did it flame out just all the sudden on the track im talking about.

I would think a filter would have to be pretty clogged to cause a random flame out. It will mess with your tune and rob power before it causes the engine to flame. I would look for another cause if it was out of nowhere that it flamed.

I just use losi or Lucky 7 filters oiled how they come and keep them fresh. Always change them before the main unless the one that is on the car looks basically new. If it is a long main I ALWAYS put a fresh one on.

i changed the outer filter after every round, there losi ones and i took some of the oil off it . well when i took my truck off the track when it flamed out the outfilter had gunk , all over it so my guess whould be it was clogged.
yea il look at my tuning, i think it was because my low end was kind of rich and my main needle needed to be leaned out a bit more. theres a small opening on the idle.
when i took it off the track, it was already cooling down it was about 215 so my guess it was running at 225 or cooleron the track but there was smoke coming out of the pipe .

right i could tell too, when i hit the throttle it was sluggish all the sudden.
it was running fine intill, the outer air filter got cogged .
before the air filter, got dirty like that it wasnt that rich.
like i said i been told, to only oil the inside of the outerfilter.
the outside of the outer filter, was pretty dirty and the inside of the outerfilter was clean.

It may take some more time in pitlane (maybe 3-5 secs more) but will save 30+ seconds in case of flame out at the end of pit lane or at first turn.
IMO This point is important even if you have a fuel gun, because at each refueling not always the tank has the same amount left, and you can exceed the top of tank anyway.
