+1 to what Hush says... And welcome to the forum. There's more knowledge here than I could ever fit onto my bookshelves.
Take your time and don't try and rush things with the carbs... you will need to source some parts (such as gaskets). The big points to check are:
1. Air-Cut-off Valves. There's one on each carb, so you unfortunately have to separate to change them
carbs wont work right if any one of theses is bad.
2. Pressed in slow jets. Pull them out and clean them ALL. Ask questions if you aren't clear on how to pull them out.
3. Fuel Cross-over T's. I'm pretty sure the t's are brass on the PD's, but the o-rings will need replacing. kslrr mentioned the honda carb bits... no joke... it's worth the $$ to get the honda stuff.
4. Float height. Set it proper or you'll set yourself up for issues (and don't install the floats upside-down like Hush did
)
Biggest mistake people make with getting old bikes running is not putting the effort into the carbs right from the beginning. So much hassle can be saved if you do it right up front (unless you LIKE pulling and installing carbs over and over
)
5. Airbox and manifold boots. If these are hard and cracked you'll have air leaks. Replace em if you need too. Well worth the money. The airbox boots aren't available as a spare part, but you can score extra's on e-bay if needed.
Have fun
Cheers, Joe
