I hear your concern.  Something someone did and mentioned the process on another forum for a clone engine was open up the jets.  He said that he couldn't get any other size jets for his engine so he took them out and used dental floss and some mild abrasive to open them up a little.  Said it got rid of all his surging and other issues relating to the engine.

Obviously I don't recommend this if you have a warranty but if it's out of warranty, it's sure worth looking into whether you can change out the jets or not, or be able to modify them a little.

Do you know what the real difference is between them?  I've swapped starters between 7, 8 & 10 HP Tecumsehs and have not found any real issue so far.  About the only real difference I've seen is the type of starter button (gray plastic with unshrouded plugin vs black plastic with shrouded plug), the length of the cord between the starter and starter button; and whether the 2 top mounting holes are slotted or not.  Obviously the tooth count on the gear needs to be correct.

If the wire between the starter and starter button turns out to be too short, here's what I've done before to mount the starter button in an alternate locations (towards the bottom):

I've bought about a half dozen or so to put on blowers and I've noticed up to 6 differences between them.

Some have a fine tooth gear vs the course 16 tooth gear.

The plastic snout that snaps onto the gear was shorter on one than the rest

The upper mounting tabs on some are slotted vs being a full hole.  This requires a stepped bolt in the upper 2 holes, but make it easier to mount.

The length of the wire between the starter and the starter button differs in length.

The starter plug is either the older gray plastic unshrouded plug or the black plastic with the shrouded plug.

Not sure what one was made for but the actual starter motor on one appeared to be a shorter length than the others.

I've swapped a starter from a 7 onto a 10 HP without a problem before so if it fits, it likely will work.  Real issue found was where to mount the starter button in some cases.
