You might pull the pump and try one of these tools?
It looks like just a ball with no 'cutting' material on it.
I welded an old ball on the end of a 1/4 rod and played with mine.
We'll see if it works.
A wood dowel and hotmelt glue gun will suffice to retain ball to smooth seat. Some tap on ball with brass pinpunch.
Little fine clover lapping compound on ball but pump needs to be apart to wash afterwards . Problem about lapping is soft cuts hard in that process. So ball or sphere on rod needs to be copper.
Having a adjustable reamer to enlarge hole below ball to establish a sharp edge for seat is the correct fix. Need a machine shop for that.
Interesting also is how seat really is. One I worked on was simply a ball sitting on a flat bottom face. What I described how to fix. The EVO sketch shows ball sitting in a probably a 60 Degree seat.
Be careful, you could make it worst. Use the shut off. But hang your on/off key on it. My old rider has a fuel shut off after my second attempt at fixing the old carb float seat. And replaced it twice.

if the pump is in your hand you can do all kind of safe things - like using valve grinding compound <n if this is the idea use a shovel or evo push rod BBC as well - it also has a 3/8 ball on the end of it and it will let you hand lap the seat
we have a re seating tool as the passage of time putting on miles causes it so egg shape - you will need to see a perfect circle in the hole before your good
Thanks all! The guy I bought it from said he will make it right. I do plan on riding it often. Living in Florida it won’t sit all winter. I do understanding it will leak, weap, and puke. Right now though, I don’t think it would start without dumping/pumping out too much oil. So, I guess now, I will wait to see what will be done. I will let yous know. But, it probably won’t be for another month. I’ll keep ya posted.
Thanks again! John
Well, I talked to the older gentleman who has worked on the bike. This is all new to me. I added oil to it (it is a big tank) he thought it may be too much. The way it puked with every kick, I was afraid to actually start it. He told me to let it start and puke. I did that and it quit, went for a ride. The next day I started it, went for another ride it ran great no puking. Guess the old guy was right!
Want to thank everyone for the help! Wish this forum was more active, I have a lot to learn!
I had my 45 up in Laconia all week, took her for a ride every morning while my crew was doing the shower/coffee thing. Amazing how well she acted after 3 days in a row of doing 10-20 miles every morning. By the end of the week she was just happy. They want to be ridden, that is the answer to most issues with old stuff.
I couldn't find the 'full' capacity spec, so I poured 5 quarts in. Damn near overflowed the tank.
I forgot that the gas tank extends into the oil tank, so the oil tank doesn't hold near what you would think by looking at it.
I drained about 1/2 quart out and fired her up - just idled a while - seemed ok.
Next day, I fired her up and dumped probably 1/2 quart on the floor.
All bummed out, I was was planning on burnishing the ball seat again and wondering if I would have to drain the tank.
With other things to tweak, I left it sit for another day and then tried it again - NO DUMPING!
I'll check the dip stick to see what the level is and that may be where I keep it?
