Good update Bob.
Lot of new guys will come on here, ask questions and never post back so we don't know if we helped or not.
Let us know when you get the new parts in and if it works.
We're always learning here too. |

I tried to connect to Messicks.com to check the price of the spring but it seems their servers are down this morning.
I guess it would depend on how much it costs.
As we talked about the other day that spring is a known failure point as the book does say it is second in line as far as troubleshooting pto problems.
If it is not too much $ I might be inclined to replace it as cheap insurance.
I did not replace mine. Just cleaned the crud out of it and it worked good after that. |
