$5 or 6$ was all to get it there. I bought a trainer off ebay. the MDS .40 was on it and had only been run once or twice, I got it to run but still cut off every once in a while , So I called horizon and talked with them,(someone had stated a recall on the carbs) I didn't even have a receipt for the motor or anything, just sent it them, and their service guy replaced carb and set it up for me, even hand wrote me a note saying what he had done and that it was now running fine for him.. Great Service from them.
I also picked up another one a MDS.40fp that the barrell on the carb will not close,
unless you completly remove the idle stop screw, so I'm gonna send it back also.
Its been a year or so since I sent the first one, I hope they with take care of this one also.
