On a electric choke which way does the spring move then heated, does it tighten or loosen? Every time I think I have the choke set, the next time I start the truck up it goes to no choke, slow idle, but after it runs a while it goes to some choke which makes the truck idle faster. It is a after market choke ,NAPA. Went to electric because of electric wipers. HELP 53 3100 root
