How do I speed up the idle on my Craftsman lawn mower
I have a craftsman push from behind lawn mower, It's only 2 1/2 years old. I bought it brand new from Sears and the warranty just ran out. The model number is 91738844. When I start the mower up, it just barely starts and will stay at a very low idle. It is impossible to cut the grass at this idle. I have already emptied the gas tank and replaced it with fresh high octane gas and the air cleaner is completely clean. There is a black plastic piece that holds the throttle door completely closed, I would hold it in the closed positon and the idle would pick up to about almost where it should be, but I can't hold this plastic piece and mow the lawn at the same time. Something is going on with the carburetor, do I have a spring missing, how do I turn up the idle. I think its something simple and the Sears service center wants $105 to fix it. I paid some where around $200 for the lawn mower 2 years ago. Please help if you can-Thank you
