crf450r hot start

I just rebuilt my carb and adjusted my pilot screw to where it sounds good, My idle is set at 1700 rpm and everytime i push in the hot start the motor shuts off. Is this a indication that the pilot screw needs to be turned out and allow more fuel in? Pilot screw is 1 1/2 turns out right now!

No. The hot start is used only to start/clear a very hot engine. It is not to be operated with the engine running. Igf the engine is not super hot, it will (a you found out) stall.

It sounds like it's operating just as it should. It leans the fuel mixture for hot starting, the opposite of the choke.

I know what the hot start is for, I watched this video last night and it got me thinking!
