Hello New Slayer owner here!

Just got my FIRST nitro truck last week, brand new to the hobby! I have owned many electrics over the years but decided to try nitro this year.

Yesterday I began the break in procedure on my 3.3. I read the manual, watched the DVD, charged the EZ-start and warmed the block with a hair dryer. The Temp outside was high 50's, humitiy 44%. I am using 20% traxxas top fuel by the way.

When the truck started it would not hold idle. Pulling the throttle trigger would stall the motor. I thought the motor was too lean so I raised the low speed needle to bump the idle speed. I restarted the truck and it would now hold idle, ( it spits fuel, and blue smoke like it should). Now when I pull the throttle trigger about half, the truck moves inches, the motor begins to bog then shuts off.

Should I richen the high speed needle 1/2 turn and retry? (because of the 20% nitro?) I really want to break in my motor properly, but I don't want to break it!!

This noob would appreciate any help, thanks!!
