Thank you very much guys for your responses!

As Shelonco said, I leaned it our more, and the blizzard works! Now the needle is about 1.3 turns out, and at this point, the blizzard runs pretty good and a good smoke tail comes out. Thank you Shelonco for your good advice!

Shelenco, you suggested swaping the tracks to the opposite side. Does that mean installing the track from the left side to the right and vice versa?

And Nomobux, what is 100 k diff fluid and how does that work? And where do I have to put it in? And what kind of bearings to where?

Also I have one more question for you guys, if you don't mind.

When pulling the trigger on the transmitter, sometimes the foward gear does not fully engage, so that I try to release the trigger and pull it agains several times, then, it engages.

Also when the gear does not engage, while pulling the trigger, if I push the vehicle foward a little, then, it engages and goes foward. But for the reverse, I don't have this problem.

What causes this? And how to fix it? Your advieces will be greatly appreciated.

Once again, thank you so much for your good advices and kindness!
