Sorry for the late reply, have had a busy week and didn't have another chance to have a play with it until now.
Anyway it seems to be a bit tempremental, the other day I cut the lawn with it and it was running at full speed but as usual couldn't adjust the speed.
Now today I went to start it and it's doing the exact opposite, it's running at idle.
The spring did seem to be working fine the other day but now it's not doing anything. But if I manually hold the governor it does stretch a little.
The governor link has no movement in the mix & max positions.
With the engine running, I can manually move the governor linkage and it does alter the revs between idle and full throttle.
It has me stumped at the moment.
