7hp 40 year old Tecumseh on my 24in Ariens Sno Thro. Last year the electric starter would "whirr" but only catch if the engine was started first with the rope start and then it could be started again with the electric start. Later, the electric start would just "whirr". This year when I plug it in, I only hear a "click" from the button as I push it. What are my sequential steps to check with this electric start, electrical, mechanical, etc.? Continues to start with the rope pull, but the electric start sure was convenient and a lot less effort.

I have a Honda HS520A Snowblower. It has a 4 cycle engine. It worked fine for the past 3 seasons. When I tried to start it yesterday for the first time this season, it took a lot of pulls and when it eventually started it began to blow a lot of smoke. It began to stall so I turned off the choke and it ran for about 30 seconds (still blowing smoke) then stalled. I couldn't get it started the rest of the day. I went back today and it started on the 2nd pull, but the smoke and stalling situation happened again. I can't get it to start again today. Any suggestions as to what might be causing this? Any help is deeply appreciated. Thanks!
