CoolP is correct. Also, be aware the position labeled START is an enrichment position for cold weather starts. In all my flying we never used this position and went directly to IDLE

I have nearly always moved mine to IDLE. In the beginning I put them on START, started the engines, then put them on IDLE.

Nice to hear that a RW 707 pilot never put them in the START position back in the day. :)
