Thanks much for all who responded to my post especially MT-2500...!
You are welcome and all of use are glad to help.,
Glad you got it fixed.
And thanks for posting back the fix and how it went
The better mileage is engine running right.
Cool weather usualy lowers gas mileage due to long warm up and winter fuel.
Good Luck
