Replacement engine has shorter crankshaft. Clutch options?

[msfixit]

Hello. Thank you in advance for your consideration of my dilemma. I'm new to the fix it yourself world so please bear with me. My son purchased a used go kart with a Tecumseh engine, model OHH60 71131D (E), family YTPXS.1951AB, displacement 195 cc which has blown up. Because a replacement piston cylinder isnt available we opted to purchase a new engine. Due to only receiving help through the regional Honda distributor regarding a combatible replacement engine, we purchased a GX200 QA2. The dilemma is that the crankshaft is approx 3/4 -1 in shorter on the new motor therefore the centrifical clutch belt isnt lining up. The motor cant be moved because it sits as close to the chain drive as possible as is. I am wondering what my options are from here? Is there is a different clutch assembly that would work? All suggestions appreciated.

Space it out to where it needs to be then use a long bolt with a large washer to hold it together.

...and the belt is facing the wrong way.

Thanks for pointing out the belt orientation. The belt was quickly put in place to show the offset for picture purposes. Because the crankshaft extension needed is minimal we are looking into having an extension milled for the end of the it.

How long is the keyway on the crankshaft?

Spacer on the crankshaft.
Then the shieve with the flat side.
Then the bushing.
Then the belt.
Then the rest of the driver unit.
Then use a long bolt.
