Hi guys, I bought this sportsman from a guy that locked up the engine. I bought a engine that had 875 miles on it. I started it for the first time last night. And it runs a higher rpm at first, but when it warms up, the idle is so slow it will die. And it is e.f.i. I looked over my manual and can not find the rpm for idle.
