After run procedure, drain all nitro, clean air filter, remove batteries, compressed air can help clean the truck, if you don't have a compressor, witch i don't, i use air cans, you find more for electronics, does not have much psi but works great for the r/c's and fits right by your wd40 and other spray cans at the track, after those steps you want to oil the engine, inside and carb, turn it over and do it over again a couple times, then its ready to sit, when pulling it out, drain the engine as you would if it was flooded by removing glow plug hold the truck up side down with a rag covering engine, and turn it over, usually i would put the glow back in, turn it over and take it back out to drain again, sometimes oil sits in the carb and wont want to come out without the compression, after a couple times of draining it she should be ready to go!
Yes that is the three stage, allows a lot of more air to come in, works great, and no problem with the info, here to help, when i got my first nitro witch was a maxx, i experienced ever problem in the book, and even ruined my first engine, tranny, receiver, and a race guard i had, come a long way now, and read a lot of manuals, so i like to help people having the problems or learning what i went through, just drove me to be a pro, before i even ran my first nitro and had it go right i had replaced 50% of it, and rebuilt it up from the frame, so if i can help I'm more than happy too!
I read in your other thread, about breaking it in, some do use the procedure were it is inside, "bench test", but, i would not suggest it unless you have done it many times, the drag the truck puts on the engine when you drive it around and break it in has a lot to do with it if I'm correct, but once, having engine problems, i took a metal box case off of an old 69' car stereo, and drilled holes to bolt in the engine and tank, and sat down and bench tested it to figure out what was wrong with it, so it is possible, be careful though because if fuel comes out the exhaust it stains bad! my porch still has stains from me starting it and a little fuel coming out, can be a mess, but I'm not sure about the break in on a bench, but i can tell you the cold wont hurt, by the time its broken in it will be set up for the cold! mine is adjusted for the cold, ran it today earlier in the snow so i know these engines are fine, but some do require different adjustments for different temps so it may be a good thing to break it in in the cold if you will be driving it in the cold!
