Hey guys, new here, im working on a troybilt tuffy crt with a 4hp briggs, the tank was rusted, it wouldn't run, i cleaned the tank and carb, replaced the diaphragm, now it will run as long as the choke is closed and it runs roughly, it starts for 3-4 second increments and twice today it started and ran for 20 minutes or so, im not sure if i have the linkage and spring in the right place, does anyone have a picture of where they hook.?
