Jesse Rieber 28 #1 Posted June 10, 2019 I bought a D160. The engine starts fine when fully choked. After it warms up a bit I try to ease off the choke and it stalls. Eventually, I can bring the choke all the way down. When I run the throttle full up it is reving fine, but then suddenly will slow and may stall. I have observed the arm to the carb that activates the throttle. When I put the throttle full ahead it seems to automatically back off and the engine revs drop. Anyone have any ideas about this?

pfrederi 18,689 #2 Posted June 10, 2019 D 160s came with 2 different engines over time. A Kohler single K341 or later an Onan Twin. Need to know which you have as some of us work with Kohlers some with Onans some with both. I know nada about Onans 1 Share this post Link to post Share on other sites

pacer 3,177 #4 Posted June 11, 2019 Onans are notoriously 'finicky' when tuning. Since this is a new-to-you tractor/engine I would do a thorough fuel delivery cleaning - get rid of old gas, replace fuel lines/filters, check fuel pump, and very likely would need a carb cleaning and kit - ethanol fuel can really gum up everything. As for the throttle backing off, the lever operates on a friction basis - look under the dash and see if you can spot a nut that the lever pivots on, this may need a slight tightening. These "Big D's" are an awsome tractor!! Share this post Link to post Share on other sites
Jesse Rieber 28 #5 Posted June 11, 2019 Thanks. I did notice there is a triangular piece which is the connection between the dash throttle and the spring/arm mechanism and that the bolt on which the triangular piece swivels is loose. I'll give that a try Share this post Link to post Share on other sites
