Hi! I have been reading the threads in this helpful forum, and have seen lots of mention of the "excess fuel button" on the little Deutz diesel air-cooled twin. I would greatly appreciate a diagram or photo or very descriptive text to help me locate this button, and perhaps a brief tutorial on its use. I read about setting the throttle to 1/2-way to make the button work correctly? I'm just not following how to use the cold-start button feature at all? Thank you! /WW

No pics but here is what i did with my 731
Look at the hydraulic pump, 2 lines come out of it and up to the injectors. There will be a small button at the top of the pump, with the throttle turned up a little press it down, it should click and drop down into the housing. That's it, nice and simple. Crank and it should start and the button pops back up.
As these engines turned off from dropping the idle to eventually cut the fuel, you need to put the throttle up a little or else there is no fuel flowing, that's why you need to do it is all.

You can look up my profile and email it to me if you want.
