Time between tanks

[Allenmr]

After full break-in and some tuning, how long should you wait between tanks? I know during break in you had to let it cool, now that it's broken in, can I just refill and go?

Its a nitro ultra lx one buggy

Wait?

I fill it when it's running drop the tank closed and give it the boot.

If it's properly tuned and hold nice temps, it probably damages it more letting it cool each tank.

Yup the most stress an engine sees, is when it cold. As long as it's up to temp it's better to keep it running.

I would agree as well, most any 2-stroke likes to be hot even to start, i just finished killing the 2.5R with winter fun, most times after i let the t-maxx cool down, it wont want to start again...

I've been starting it using a heat gun, we've been getting a ton of snow here this year, so all my break in runs have been in about 40 degree F temp and after that anywhere between 25 and 40

Thats not good, most recommend 50+. Even 50 degrees can cause issue, the cold weather will tear up the engine if run a lot, i just killed my 2.5R with not even half a gallon run through it because of the snow, it is fun i have to say, but it will shorten the engines life quit a bit!

Thats a bozo no no those cold temps are hard on a engine more so when its new. You might wana plan on a rebuild for the spring so you got something that runs good. If plan on cold weather running keep a engine around you don't care about don't kill a new one.

 

[Allenmr]

How will I know if somethings damaged? Will it just run poorly when the weather warms up?

Yep. High likelihood of it having weak compression and flaming out on your once the ambient temps are up above 50 or so. On the plus side, you have a winter engine now. That's what I usually do. I run my old tired engines in the winter because it's so hard on them. I save my good engines for the warmer months.

Save your pennies now, by spring you will have enough to get a new summer engine.
