HS40 Throttle linkage works only when engine is OFF?

#1
Hello,
Set up a new tecumseh throttle on my HS40 snowblower engine circa 1970. The set up works flawlessly until I start the engine, then the butter fly moves a hair and no more. Turn engine off and it will work again perfectly. At my wits end. Please help as my son really wants to ride my minibike

And after you bend that in, adjust the governor. Loosen the little screw at bottom of governor arm, push the arm wide open(to the right) and re tighten the screw. Should operate like a champ.
