Thanks Grumpy, reading your comments again, I have mixed the two springs up.

I'll start again so all is clear.....

As I said in my original post, I stretched the governor spring (Item 209) when taking off the engine cover and I have replaced the spring...purchased via the OutdoorKing website smile

The engine starts, but I can't adjust the throttle (engine speed) via the factory lever on the side of engine. I haven't touched Item 211 spring, so assumed my issue was only related to the Item 209 spring. confused

I assume now I need to treat these two issues separately.?

Both springs are slack when the engine is running. I understand now how to adjust the Item 211 spring. But not the Item 209 spring.

I was hoping to get a photo of the carby layout to make sure I have everything right. I wont be able to get a photo of my engine until this weekend.
