Just this year my Ariens 824 with a tecumseh engine starts after I prime it a few times and suddenly stops. I checked the fuel lever, and it's fine. I checked for any objects that could be causing the machine from starting. I also changed the spark plug and when I did that the machine starts faster and runs longer, but then it just stops. Also, I recently lost the gas cap in my yard somewhere. I am currently using a gas cap from my leaf blower. I was wondering if there are any tips as to what I should try. Also, I was wondering if this problem could be the result of the replacement gas cap.

Thanks in advance for your help.
