Ever noticed your fuel going off? Bit of a head scratcher...

[Yoshimoto]

This has happened a couple of times this year-nitro going off-the last 1/2 a litre of a gallon is not the best and causes major tuning issues-it just will not run right...its usually over 2- 3 months of being carefully stored,the last remains are always poor-im just gonna label the older fuel dregs 'cleaner'  to be safe,the 1st time it happened it took me at least 30 minutes to suss out 

Its been making a clean tune impossible-16th of a turn either way on the main needle is like too much or too little every time.

you should open a new bottle and pour it into smaller bottles.

^^^^^

Same as coka cola if you crack the lid off 10x its flat wether you've had 10 swigs or 10 glasses lol.

I buy litre bottles then try to squeeze it so theres no air left in when i close it. The potent stuff evaporates but they say any open nitro goes off after two months. Keep it tho for cleaning engines and stuff.

Mmmm. Wonder if this is why mine don't run at its best. ? The fuel come with the car and have no idea how long the guy had it before me.need a new bottle soon anyways

[JayAVFC]

This must of been the problem with my car before I sold it the fuel was three years old and the engine was useless

[J.K]

On the flip side, I wonder if it depends on the brand? I recently finished off a 2 year old bottle of Byrons race gen and it was perfectly bashable with no tuning issues at all......it was in my Firestorm tho which has a fairly basic .18 engine.

I believe an engine is an engine-they all pretty much run on anything with some minor tweaking and perhaps a plug change-i mostly use RTR type engines so try to stick to a minimum 18% oil and 16%+ nitro and thats the only consideration when choosing it really other than price/value/availability.

Ive got some Tornado 20 to try if it stops raining and that should put my tuning issues to bed.

I hope so..i changed the main needle and valve last night to rule that out,its the only other thing i can think of-there was the smallest amount of wear half way up the tapered part of the needle-it only amounted to just more than the grey factory coating but something to consider.

oh...the sun is coming out...

when i was into flying nitro RC planes all the old timers had the fuel in smaller bottles. 

[Yoshimoto]

Yeah it works-i use a filtered 500ml bottle for everyday sessions...its well sealed and will hold overnight to a day or so no probs
