My Revo engine is about 3 years old. I don't use it that much maybe 2 gallons of gas run through it. I don't think more than that. Lately I have been having an issue with tuning. When I gun it, the engine bogs down and shuts off. I have tried to tune the needle and every time I think I have it, the same issue comes back. Weather has been a bit humid which I am sure does not help but my question is, is the motor worn out or do I just need to tune better. If it is worn out is there a way to repair it or is it better to just send it in for a new one? The motor has not been abused- Having said that I often do not do the after run procedure. Thoughts?
hsn is too lean. richen it.
I have rochened it and may help for a few seconds then back to where it was
When a nitro engine has lost compression they will usually start and run fine when cold, but will die at idle when it reaches running temps and wont start again until it has cooled off. When they're running to rich they will boooooog. And when they're running to lean they will b-o-o-o-o-o-g. If that makes any sense.

Feel free to read over this sticky, along with the owners manual (there's a copy in the support section) it should help out if there's a tuning issue. http://traxxas.com/forums/showthread....&goto=newpost
Hope it helps, feel free to post before massive hair pulling begins....
You'll avoid the hair pulling if you go over the sticky I posted and read the owners manual especially about the part of the carburator and tuning for performance....

Hi Everyone just want to say thank you. I am going to try all of the suggestions. Humidity is gone and I may have some time in the afternoon.
One other question. I have watched y LHS tune and he runs the engine and hold the car in the air and runs on WOT to check the tunes. Is this okay for me to do? Seems easier than running down the street and it konks out half way
You should never rev high rpm's with the wheels off the ground, it's very bad on the motor. And it takes more than a couple of seconds for adjustments to the tune to take full effect.
