Yup, that usually seems to be the problem when all else is okay. Believe me, you are not the first nor the last.... been there done that and 3 or 4 guys here have done the same thing.
As for the choke rod, you should be able to make one, but getting an original or a good repro is better. David
, or Tom
should have one relatively cheap. Far better than making one.
Also, if you are going to Cub-Arama, John probably can put one aside for you so no shipping involved!
And, as for adjusting the clutch, just in case here is the link to the thread on that thar subject! That Special Feeling
. The title seems to be apropos for your situation at the moment
Congrats on getting Annie running again, and you will remember that feeling every time you fire her up
Lookin forward to seeing pics.
