Once you get it up and running again, you can get a foot switch that allows the saw to run as long as you hold the switch down, sometimes called a dead man switch.
I have one from Harbor Freight I got for $10, actually $9.99, they market 2 foot switches the other switch turns on with a push, then you have to push it again to turn it off. It's about 2 bucks more.
I prefer the first one, if a blade breaks or anything like that you will automatically take your foot off the switch by reflex. Good safety feature. The model number is 96619 for the dead man switch.
and 96618 for the push on push off switch. These are not dust proof switches or water proof either. Occasionally if you have a lot of debris on the floor it can block the switch. I have a gravel floor where I work, and it sometimes gets in, I just tip it up on it's nose and tap it a bit and back to work!
Hope this helps,
