Is there anything wrong with that??
When I run my t maxx I notice fuel coming out of the exhaust nozzle. Enough for it to somewhat puddle at the end. Also when my truck turns over, I can see where the fuel has sprayed onto the sidewalk. I'm only talking a little bit. No gushing or anything.
I've followed all the instructions about tuning so I think I'm doing that pretty right.
What do you think??
Fuel coming out out of the exhuast can be normal if it's too rich, so it sounds like your running too rich... Try leaning out the hsn a little bit and that should help... Good luck!
I think if it runs good and you have power, keep it just like that. Running your engine a tad rich is good. It will make it last a lot longer ecause of the extra lubrication.
"I like rc cars"....."WHAT? YOU'RE KIDDING!"
True, but normally when there is fuel coming out of the exhaust, that normally means it's running WAY rich... But your right upbasher. Sometimes it can be normal.I think if it runs good and you have power, keep it just like that. Running your engine a tad rich is good.

It's normal, I was running mine perfect and still got fuel out of exhaust. Your fine

Also the added friction will create premature wear of the piston and sleeve, bringing your engine to a short life....
Best thing... check the temps, should be between 210-270, no more, no less... The rest is tuning by smoke trails combined with performance...

I spent What??
You know the Blue Smoke thing is Kinda Confusing as I was tuning mine after Break in and I was getting alot of Blue Smoke but it started to Cut out so I richened 1/4 turn and it seemed to be ok but man I get a Ton of Blue Smoke, so much the Area I am running gets a Blue Smoke haze hanging around.
DO not have a On-Board Temp or one of those Temp Guns but the Drop test gives me about 2-3 Seconds Sizzle so I believe that is in the safe range as far as temp is concerned.
I noticed I get alot of Fuel Spewwing when I first Fire up but it seems after a couple Runs and 1/2 below throttle to warm up engine drivetrain (which comes to be about 30-45 seconds of running) it seems to stop completely or get to where it is hardly noticeable.
But I have noticed last 2 days when I first start up it seems to spew fuel both times I thought what the heck happened to my Settings I had worked so hard on getting perfect but since I need to tune when it is at operating temp I warm it up and it seems to go away and my setting are fine.
I have seen engines with the HSN too rich & LSN too lean have lots of smoke but still be over 300°F from being too lean on the LSN, if it's cutting out that is a classic sign of being lean & hot.
Spend the $25 & get the IR temp gauge, it cheap insurance as the spit test is not really good way to judge.
Look out for the tree/crunch!
LiPo? Naw NITRO!!
Temperature and humidity levels can effect the amount of leftover oils that spew from the stinger.
I use the 'spit' test, have never used a temperature gauge but the test works very well.
More fuel also means more heat! Not sure If it. Apples to gas rcs (I'm an electric guy) but in a 1:1 vehicle typically you don't want more fuel because than your engine runs hot!
