just a question really as im having mega trouble starting my rc nitro buggy,

does the fuel go off????, ive got some which is about 4 years old, and is it knackerd, cos it will sort of start, rev for about 20 seconds then die......

so is it best to get some new fuel
thanks....

that would be a good start yes. Fuel attracts water and therefore does go off. Might be wanting a little bit of a retune as well. I generally run slightly rich after a pro longed period of leaving mine sitting and back off the throttle as well then lean out again once it gets properly up to temp and engine has been working for at least 10 minutes or so

yeh fuel goes off. it will smell really funky too. any small holes in jets and carbs etc normally end up jelling up so to speak if the fuel has been left in. sometimes need airline or a hard blow/blast of air to clear it through.

best thing to do is when your not going to use it for a long period drain it and start it up to burn off any fuel thats left in it

Buy some new fuel

Preferably O donnell or tornado

I'd say O Donnell as Tornado is a race blended fuel with more regard for power than lubrication. I'd say get O Donnell 20% R2R. Plenty of oil and lube with the extra bit of nitro for the kick.

R2R stuff is shit.. ran it once and never again.. Tornado or O Donnell race blend is the best stuff

thanks guys, ill try new fuel, i tried a new glow plug today, but totally pissed off now with it, my arm is gonna be sore tomorrow, been trying to start it today for like 3 hours or more, suddenly it will go, but wont stay running.....is 3 turns out on the mixture about right?

i tried it lean and rich,

I've never run race fuel and my hand tuned picco P1-R is running pretty damn sweet on 20% R2R.

And this is a 2.5cc 7 port modified race engine. Not BRCA legal but goes like the fucking clappers!!

hmmm what engine you got mate. 3 turns out on the main sounds about ok. Where is the low speed screw roughly? Should be near enough flush with the carb barrel approximately as base and slightly in when tuned.

stage 3 muppet

nitromethane fuel if it is will go off very quickly pal ......... i would say 4 yr old fuel is good for fook all apart from lighting your barbie lol

Nick.

Still wouldn't run R2R

Race fuel FTW as they say

rik-rs

its one of these, had for about 4-5 years now....

i tried the low speed screw in different settings,.......

rik-rs

ok i`ll get some newer, hope it is that......fukin arms gonna fall off with all the pull start jerkin...

the fuel i have is that blue thunder stuff.....

Nick.

ahh Blue Chunder as they call it.. used to run it and hated it because it was too oily..

Run O Donnel race formula or Tornado 25% but make sure you flush out the engine and fuel lines first to get rid of the Blue Chunder left in there

Blue Chunder lol, ahh the days back when I was hooked on RC and knew everything and every new product and car that came out. If its just for a bash mate, I wouldnt run race blended fuel as it severely shortens engine life and puts more strain on bearings. But anyway out of the two I'd run O Donnell 16% race. More forgiving than Tornado and is a very good blend of fuel. Ran a few engines on it and quite impressive.

thanks guys, can you buy the fuel in like 1 liter sizes or anything, dont wanna be buying a gallon, cos it will be getting launched if i got loads of fuel and still dont work...

Yea fuel is probably off. I always use tornado 35% for my savage. I'd say the best thing to do is to virtually give it a full service. Clean the air filter, fuel filter (if its got one) clean the fuel lines, clean the carb out, replace the glo plug, and more or less turn the settings back to factory and get it running and finally fine tune it after.

Hope this helps

might have fouled your glow plug mate or your glow stick hasnt got enough charge to start it
