Hi all, Im new to this board but have a question for a friend who has one of these sleds. His choke circut doesn't seem to be working and I know nothing about this DPM setup. He keeps his shed at 65 degress just so the sled will start, after it is warm it runs fine like it should. We have checked all fuses and connections and can't find anything wrong. He been riding but he can't let it sit too long or he's stuck. Anyone know of this model having problems like I described?thanks for any help
