Ok since I've had the 74 I've always needed to ensure the hand throttle was wound up before starting or it wouldn't idle. Even after driving the hand throttle would back itself off and it wouldn't correctly idle by itself.

Eventually today I googled how to adjust the idle on a 13B-T and up came a really cool site: http://repairmanual.free.fr/_engine_manual_3B_13BT.pdf

Printed out the pics, took them down to the car. They suggest that the 'adjusting lever should be touching the idle speed adjusting bolt' once the accelerator is released. I checked my adjusting bolt and it's nowhere near long enough to be touching the lever. Not a snowflakes. But the truck is like dead stock with 100 000km, I don't see why this would be changed from OEM?

Unless there's something I'm missing.

My first thought was to find a longer bolt and whack it in but it seems *twilight zone music* too weird that the 'stock' one is about 1/2" too short.

EDIT: Now that I look at the pics I notice there's two bolts. One in the lever that moves, the other in the plate that is stationary. I ain't got the stationary bolt. :shrug:

Why does the hand throttle back itself off? Mine stays in the same spot forever,maybe the cable screw is worn.

As for the bolt not touching ,I think my last HZJ75 was the same,it missed the lever by about 10mm.It was never a problem.
 
I wouldn't worry about the adjustment lever thingy.

Adjust the "idle speed adjustment bolt" to about 800-900 rpm or when it smooths out and your idle, problem will be solved. Its a bit hard to get at, I think its a 10mm for the lock nut then you can turn the bolt by hand. access it from the wheel well.

My hand throttle also does not move...
