When I rebuild a carb, I dissasemble it on the bench. I put down a big clean shop towel, and as I remove parts I lay them to the side , when I get to small parts, I lay them on the shop towel as they wont roll away, and it keeps them plainly in site...helping not to lose them.
I would also say to rebuil the carb yourself. The Kits come with step by step instructions.
Bogging sounds more like fuel starvation to me, also sounds like it does OK when you feather down on the gas, so I would start at the carb.
Fuel delivery could be an issue, so you might want to check fuel pressure as well.
A gauge like this and a few fitting to do the job are relatively inexpensive
Harbor freight sells them ( I hate harbor freight) but this one is good. It will also help you adjust the carb and do other diagnostics on your engine. Quite possibly the best 15 bucks youll ever spend on a tool.
