Again I am new to this hobby. Received my brand new Revo a few days ago. Just finished breaking it in last night. Was on my 5th tank of gas and going through the 5 second count to full throttle letting it shift into second. Problem is when it shifts into second gear. It wants to cut out a few times before it shifts into second. Almost like I let off the throttle 2 or 3 times then hit it full throttle. It keeps going and does finally shift but the RPM's are lower and it takes it a while for the Revo to get back up to speed in second. I am getting a little trail of blue smoke. I dont have a temp gun.

Out of the box I have only touched the high speed adjustment tuning for temperature and humidity. Making it richer 1/2 turn. I have played around with this adjustment making it leaner and richer and it still bogs down while trying to shift into second.

Any help would be appreciated....want to get to our local track by this weekend.

kinda sounds like its running a bit lean. When its lean it might studder for a second the shift. Try richening it up about 1/4 turn counterclockwise

i saw it said 1/2 turn. 1/2 turn on the carb makes a huge diff. small changes are the way to do it. Also try turning the high speed all the way in the backing out 5 turns, then go from there
