Yes Bushie I agree, I will try it to see how it goes, it is only 2 x 10mm nuts to put it back to original.

I have striped 3 of these engines now and have put what I consider the worst one back together.
With the carb and governor set up, I remove everything now (carb, governor arm & throttle control plate) assemble all the linkages then put it all on the engine in one hit.
A tip is to scribe a matching line on the governor arm & shaft before removing it.
This arm is reassembled with the shaft rotated fully clock wise the arm fully rearward.

I have drilled the jet out the next size up 0.85mm. Will let you know how it goes.
I had to straighten out the linkages and springs as they where a mess, if they hadn't been played with, it would tune up a lot easier.
