Tecumseh Carb Replacement Oops!

In our enthusiasm to replace the Tecumseh Carb (part#640084B) on our Craftsman 5HP Snowblower we forgot to detail where the linkage hookup holes were on the govenor plate before we removed them. When we try various hole combinations on the new govenor plate and the original user speed control and nothing noticeable happens with the spring tension. Is there a way to start from scratch and set the spring tension correctly? Because now I see a warning that we could blow the engine if this isn't set right before we restart the engine. Oops!

I am assuming you left the spring from the throttle control to the governor arm in place as there was no need to remove to change carbs. The rod goes from the top of governor arm to the throttle plate on the carb. If you look closely on the gov arm you may see some wear on one of the holes (assuming there are more than 1). You do not see much movement when throttle is moved from idle to full what you should notice is when at idle there is no tension on the governor spring/arm and when you move to full there is tension. Here is a pic that should be similar
