I bought a 2000 Xpedition 425 not running for a summer project with the grandson. We had to replace the CDI with an aftermarket and clean the stator to get fire. Now it idles for one minute and dies. It will start back up immediately, run for another minute and die. The fuel pump, carb and fuel lines are new and we have good flow. We checked the vent line and tried running it with the fuel cap off, same results. I even which out the CDI again. Any help would be greatly appreciated. I would like for him to get to ride it before he goes home.
