I'm new to nitro, and I just got a CEN Matrix, and noticed that the fuel lines are really long, long enough to encircle the engine, and lay on the pipe. Is there a certain length that they need to be, or can they be shortened or maybe just rerouted? It seems that they would have to withstand some pretty hot temps, burned my index finger today during 4th breakin tank, OUCH ^$#%#![:'(] aNYWAY THE CAR SEEMED TO BE RUNNING GREAT THIS AFTERNOON, BUT WHEN i TRIED TO START IT THIS EVE. (oops sorry bout caps) I had a really hard time. It would run, then die, then it wouldn't start at all, then it would then die etc. Really frustrating, My friend also purchased a CEN product, and had simmilar probs, he has the GST.
We're going to the track tommorrow, maybe someone there can help us, till then any info would be greatly appreciated.

the fuel tuping you can cut it reroute it whatever it dosent matter just cut it the right lenght you will need.make sure you start leaning it in a little bit at a time at about the second tank or what ever the instructions say, and you could have a bad glow plug that is pretty common when breaking in a new engine will it run if you leave you igniter on it and ween you take it off it dies if so its your glow plug hope this helps.

Yeah, like chrpwrs says, it is pretty common for glow plugs to die during or right after break in, due to the very rich conditions.

As far as the fuel line goes, those rubber lines can withstand some pretty impressive temps, but if it does get too hot, there is a chance of the fuel vaporizing and causing "vapor lock".
But, when your unit flips over, the fuel level in the tank is now at the top of the tank and if the tank isn't right full, the level will be below the intake point in the tank. SO if you have longer lines, your unit will stay running longer than with shorter lines, simply because of the fuel capacity of the lines and filter.

Thanx guys that helps alot, I also went to the cen website, and got the engine settings, my low was off by quite a bit, could explain the bogging. I really appreciate all the usefull info I get in this forum, keep up the good work Samaritans.[8D]



anything worth doing is worth doing my way,ehem.

We finally got my Matrix running half decent after about 3 hours of f#$%%$g around with it! Turns out that the factory settings are way off for the car. My bottom end is about 2 turns in from flush, CEN recommends 4.5 -5 turns out from closed, thats about 5-6 turns difference. Could be the climate here in Canada though, although we don't ,contrary to popular belief, live in igloos, it is quite a bit colder than So-Cal I bet. Today was a nippy 40 deg. f . Also I removed the fuel filter in the line, I think there's air coming in from it, has anyone else encountered this?
Anyway we finally got it running, WOW! this thing hauls *****, really suprised alot of truggy drivers. after about 3 tanks after the initial break in, this thing WOKE-UP and was screaming, A dude in a Savage truck was trying to pass me, and I was toying with the throttle, and pulling away. I hope that there are more fun days like this.
Broke 1 part, I was running with no body(on the truck) and my freind in a hopped-up Revo ran over me head on, broke the steering arm, and fixed it with a zip-tie, HA!

i am glad you got it going man let me know if you need help with anything else.
