There are setting screws on the side of the accelerator arm. One is for high idle speed, the other for low. I'd get a book on how to adjust however.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.

skip Posted August 23, 2011 Share Posted August 23, 2011 Get a 7/16" spanner and crack off the tall looking nut with the adjuster screw in it behind the throttle arm, on th back section of the fuel pump. I cant think off the top of my head but I think you turn the adjuster screw clockwise to increase the idle. Then just tighten the lock nut up when you get your desired idle. Cheers, Skip.

Kav Posted August 24, 2011 Share Posted August 24, 2011 We had a similar problem years ago after the Fuel Pump had been serviced. On some of the spec Sheets the idle fuel setting was too low and they used to stall when you stopped at the lights. When you got the Idle fuel lifted a bit in the pump they were good.

tanbuddy Posted August 24, 2011 Author Share Posted August 24, 2011 I got it to idle up to 600 rpm today, it made a big difference. I wanted to get it to 650 but the bolt isnt long enough, theres only 3/4 of the locknut threaded onto the bolt now as it is.

If you've not replaced the spring arm the throttle linkage attaches to, this might be a good idea as they do wear although you can't tell by looking at it.Rob Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke.
