Need help with trolling motor

[Kent]

I have a 2003 Johnston 4 HP four stroke that I am having a difficult time getting running this year. I rarely troll, so it hasn't been used since last year. It has always started and run fine, but for whatever reason it is struggling this year. It will occasionally start, on full choke, and run for a few seconds and then die. I have replaced the fuel and replaced the spark plug. I live in the Bountiful area and would love to find someone who has some skills on working on these motors (I know some great boat mechanics but none close to where I live).
