Anyone have any tips to get the bog out of the bottom end of my engine?
It's an LRP Z.28R Spec 3 in an Associated MGT. I have the high end figured out and it flies but it bogs pretty badly when coming off of idle. I tried leaning it out ~1/8-1/4 of a turn on the low/mid needle and it started not being able to hold an idle, went the other direction and the bogging just got even worse.
I am running 20% Traxxas Top Fuel with the stock gearing, and as I said earlier, once it is moving it just flies, but down low it is just annoying.
I have about a gallon on the engine, it still has an insane amount of pinch, and when I take the temp it hovers around the 210 degree range.
Any help is appreciated."

When you leaned the low speed needle did your idle get higher? If it did lean the low speed needle end out by 1/8 of a turn at a time and also lower your idle by twisting the idls stop screw counter clockwise.

Your fuel is the problem.....IMO the best are Nitrotane, Byron, and Sidewinder.

It actually could be the fuel, not because it it Traxxas (but once it gets closer to summer I'll switch to Byron's), but because this gallon is about 5 months old, and it was stored in a fairly cold area.
I'll crack open the fresh gallon tomorrow and see if that makes a difference.

also i think top-fuel has a very high oil content but idk what that would do. I really just thnk its a tuning issue.

Get some Byrons Gen 2 25-30%, lean the bottom, add 2 thicker clutch springs and keep one stock, run Dyn max lifes.
I raced a full cf shassis LST2 with a LRP Spec 3, still have it actually, thinking about selling it as I run Z-Car buggy and soon to be truggy now

you can run mc 8,9, or 59. I always ran mc 59 in my LRP .28
