Hello, I am new to this forum and wanted to see if someone may be able to provide me some guidance? I have a Huskee Supreme SLT 4200. I has the lever similar to a turn signal on the left used to engage the blades. I recently purchased the mower at an auction and it seems to run great. However, when the lever is pushed forward to engage the blades it causes the motor to choke and eventually shut off. If I push the lever about a quarter of the way they turn and the mower still runs but at about 50% up it starts the choking. I sure hope someone can provide a clarification to this and possibly a simple fix?? Thank You,
