All Done With Break-In (Now i Need To Know This....?!/!?

[R-MAXX]

hello,
thanks to everyones help in here i was able to get my truck through the Break in process without too much troubles...

So now its time to tune it for performance...I went on Traxxas.com and got a great article on how to tune it for performance...but the just say to lean the HSN 1/16 at a time..but what i really wanna know is what everyone in here turned the HSN too...so i can get somewhere in the correct ballpark..i know everyones is probably somewhat diferent but not by that much...

right now everything is still at factory break in settings.

So how many turns of the HSN did you do to make the MAXX run leaner and at its best???

thanks guys

Not to be a total jack, but the best thing to do is probably to lean the HSN 1/16 or 1/8 a turn at a time. All needle settings are going to be different due to humidity, elevations, etc.

hey whats up.
i tried to tune the carb tonight...and i had nothing but trouble.I started the truck, i warmed it up....i adjusted the HSN 1/16 leaner and the truck started getting really hot...and steam started to come from the head and i shut her down!?!?!?!?

*** is up with that?

so i tried to bring it back and richen it, then i tried to lean it..and before u know it i had no F'N idea where i was at with the setting..so i stopped for the night!!! lol :o

when i got it home i closed the HSN all the way up and turned it 4 turns..so its back 2 factory???

what do i do? HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!

could the idle be to high? if i turn the idle down the truck will stall cause its so rich i believe? its driving me nuts!!!

I don't know about the rest of you, but my low mixture screw was way too lean from the factory, maybe your bottom end is too lean, will it sit and idle through a tank of fuel without reving up and down? If it won't, then your bottom end is too lean. I had to richen mine up by about 2 turns. Try running it through a tank of fuel at idle and listen to the engine, if it starts creeping up, richen the idle mixture till you have a constant RPM out of the motor, and the head is the right temp, then proceed to the high speed needle, this will rough you in. Then just adjust your idle mixture a little at a time to get that hole-shot, then hit your high speed screw, and you should have it.

here is what i have found with mine.

When it starts to smoke off the top of the head SHUT IT DOWN INSTANTLY!!! you will ruin your engine!!! wait for it to cool and trun the HSN COUNTERCOLCKWISE 1/4 turn. Start her up and see what happons. drive all the way through the tank UNTIL A it startes to smoke again. Then just repeat the tasks from above. B It loses power. if you stomp on it and it starts to make a deap low "growl" and dosen't go any where. To cure this richen it up! dont lean it out like its "choaking on fuel"!!

ALWAYS make sure there is a blue smoke comming out from the exhaust, and ALWAYS tune the HSN BEFORE the LSN, the HSN controls ALL fuel flow into the carb. The LSN controls what the HSN is letting in at lower speeds. Get it? Hope So!

Hope this helps! DONT GIVE UP!! Start at the stock settings, and work from there!
