Hi, I have a Chrysler 12.9 hp motor that has very low hours and is in like new condition still. The engine data tag says 122HD and 5170. <br />Does anyone know what year it is?? I believe it to be a '70 or '71.<br />Also it is giving me a little trouble at a low speed idle. The motor is cutting out and back in at idle. Anything above idle and under a load she runs great. I noticed giving it a tad bit of choke at idle prevents the problem so I assume it is a lean mixture problem, but not sure. Any help and guidance would be greatly appreciated. Thank you.
