This is a shot of the carb from above with the starter rope bracket removed. You can see the bolt on the right clearly. It can be loosened easily enough. Possibly it could be loosened enough to back out of the block, I didn’t check. As you can see the air silencer is nearly touching the lower cowl so there is no access to the left side bolt from above or the side. The lower cowl is 2 pieces held by clips and bolts at the top (above the shifter and tiller arm) and bolts underneath. When those are removed there is easy access to the carb bolts for removal or any other necessary maintenance.
Thought I would add a picture and a brief explanation in case someone searched this motor or issue as there is very little information about it out there on the world wide interweb. Might help someone out down the road.
