Hello, I recently purchased a ORN80679 CRF Alpha .21 ABI Buggy Engine (ABC/5-ports ceramic).

Break in went great. Pinch is gone and the engine has great compression. There is about 1.5 gallons on the motor now.

Problem I'm having is with getting the engine to idle properly.

Plug Changed
Fuel line Changed
Pressure Line Changed
D8 Tank changed to RC8 tank old
RC8 Old Tank changed to a new RC8 Tank

.5mm It will idle for maybe 5 sec and die
increments there out to over 1mm it will idle longer 8 - 10 at most but still die.
(Of course I'm adjusting the LSN to try and get this to work right)


More info:
Motor is always warmed with a Comp Heat heater
I'm in Iowa where it's been in the 90's and 100's for the past month with high humidity



The motor is so new I would hope it's not a bearing or an O ring somewhere.

I did seal the motor up as suggested by a guide from a TLR driver on Youtube before doing the break in as well.

Any suggestions where to go next
