Hey I've just put my 4th tank through my Matrix and I took her to the local BMX track today to put the last 2 tanks through it before I started leaning her out. She has always started fairly easily and this morning was no exception... except.. it started stalling after 5-20 secs, often before I even touched the throttle. Thinking the plug had died I replaced it with a brand new one. That did not help. So I reset the needles to factory defaults, again the problem wouldn't go away. I slightly increased the idle, then richened the mid and low end, no good, leaned it out as well and it still dies. Getting a little frustrated (friend is up and running with his Swift thing, makes me annoyed I can't join him). I then replaced the fuel tubing, cleaned the mid range needle as well. Problem is still there. (Using a Cen Rotostarter, then my mates Ofna Starter Box, to no avail).
Car starts up, runs well, then 10-20 secs later it stalls. It has fuel flowing, no blockages either, really am baffled. Sadly I gave up and came home, want to try again tomorow.

Can anyone lend me some clues?

Thankyou in advance.

Anyone? 2morow is my last day off before I do 8 days straight, really want to get it running:P


Baffling/annoying problem, every dam needle setting in the universe, starts, runs ok, 10 secs later stalls. Fuel is flowing, no air bubbles, normally retarts after a stall as well. Idling nice n quick. Leaving the glow starter in does not help.


HELP ME PLEASE!!!

check your fuel tank for leaks around the seam.mine did the same thing after i replaced the tank it ran fine

eeerm... very strange!

... try some of your mates fuel... might help.

Is it bogging then stalling or reving up and stalling?

Thanks for the replies.
The fuel tank is sealed, there are no airbubbles escaping and the fuel I'm using powers my old Inferno DX without a hiccup. Also use it in my Nitro Tourer. Its a 20% compertition mix.

Mine did the same I would just have to let it warm up for about a whole minute and then I would pick it up and rev it up and it would be fine. Just cold blooded I thoght. Now it is just a routine.
