The electric starter works well. Jacks Small Engines website was very good and I would definitely use them again for such purchases. Attachment bolts that came with the starter kit were not good. They had small/shallow heads that were difficult to turn with a wrench (or anything else). The starter had metal tabs with holes drilled in them, to attach to the engine block. These holes did not line up with those in my Tescumseh engine block, so I had to drill larger holes in the tabs to adjust for that.
Shipping time for the part was too long. It took 5 days to get from Jarrettsville, Maryland (less than an hour drive from my house). It was shipped via UPS and USPS carriers and went from Jarrettsville to Baltimore, to West Virginia before arriving at my home in Mount Airy, Maryland. That wasn't Jacks Small Engine's fault, however.
