Title: 92 FJ1200 stalls at stops after warm up
Post by: wam48 on January 07, 2011, 12:18:22 PM
I recently purchased a 92 FJ1200. It starts right up and runs strong. However, once I'm off the choke it stalls when I come to a stop. It will start and run on choke but will not idle with choke off when hot. I've gone over basic maintenance and tried to adjust idle without any impact. I'm about to trailer to shop, but thought any insights would benefit both me and my mechanic.

Plugged low speed jets.  Either clean them with ultrasonic cleaner or get replacements from Randy-RPM.  If your intake/exhaust i are stock, get #40. Otherwise, probably #42.5 are in order.
