The motor came with a red clutch spring, do you recomend to use that one or i have a slightly smaller silver spring that has come in another kit that i could use aswell. The reason i say this is because i started it up on the weekend and the second it kicked over it started pinging off it's head and the clutch was engaging while the wheels were off the ground. When i took the clutch apart i found the clutch spring had to much tension on it, so i backed some off. But when i was putting it back together it felt like the red spring was to hard for the set-up. Should i change it with the smaller silver one or should it be ok??? I'm just hoping that this was my problem not some other under lying problem i can't see yet.

Anyhelp would be great as i really want to get the best out of this mill.
