I might try the stock length spring I replaced with the Sonnax spring . I later clipped a little off the Sonnax spring but I may not have clipped enough or I might clip one back to the length of the stock spring . Sonnax sends 5 to the pack so you have plenty to play with . I set the cable by pressure gauge . . . . loosened the cable at idle . . . when pressure went down as far as it would go then tightened the cable to raise pressure up 5 lbs and locked it down , had good line rise so I quit and had a cold one . My pressure gauge reads in 5 # increments so it's not the best .
