Default Stalling when low on fuel.

Hello every1,

Is it common for a buggy to stall when its low on fuel?

I was trying to run my buggy out of fuel on the weekend and even where there is a small amount of fuel left in the tank and im driving it slow (so as to not let the revs spike) it kept stalling. Is this common?

Seems like it gets allot of air in the line which is what is causing the stalling.

About how many MM of fuel level is left? Its normal for a little fuel to be left behind in the tank.

If I'm taking it easy then my car is much more likely to die with a low fuel level. If I'm running hard on the track with slightly rich settings I can just about completly drain the tank before it dies.

How much fuel do you have to have in the tank to not have air bubbles in you pick up line?

Very small amount in tank before it starts stalling, 2-3mm in tank before this starts happening. I think its when I take a corner the fuel gets pushed to side and then air gets in line.

I really dont think its over heating or running lean. My local hobby shop gave me a 'safe' tune because i wont be racing just yet, it doesnt even get that hot, when I do a spit test there is a little steam but it doesnt sizzle or even bubble, just sits there fore a bit.

I don't think I'd worry about it much if it runs fine everywhere else.

What kind of car is it?

Model is BS802T, I bought it over ebay. When I took it to my hobby shop they were surprised how well it went, how much poke it had.

Its got a .21 3.5CC CXP. It was very cheap so im not expecting a great life span from it but I do take care of it, run it out of fuel, use after run oil, keep it clean etc.

I dont think its anything serious, just curious as to why its happening, ive been told when its running out of fuel not to rev it too hard but when I try to put around on low fuel it always stalls and I dont like leaving fuel in it when im finished for the day

You can run it a little harder.

If you run out of fuel while at full throttle under load the engine will go lean as it runs out of fuel. (not good, lean=hot) Chances are in these little engines it might not be a big deal.

i will try running it a little harder and see what happens, just make sure I dont give it full throttle.

does everyone else run it out of fuel after a days play? or just put it on a stand and let it idle empty?

run a longer pressure line, lengthen it to about 10 inches.

Come to think about it because the fuel tank is pressurised if I dont have enough revs how will the line be able to pick up the small amount of fuel left in the tank?

Ill def. run more revs next time im running it out and see what happens.

Thanks guys.

j/k

reading some of this it surprises me that some of you pass tech.

Sounds like a small leak or your to lean. replace all fuel line - go back to factory needles on the engine and start over. how old is your fuel tank, could need a new lid
