Thanks for this. Love that you keep it real and show your day to day happenings. Life is all about how you bounce back. Love how you tackle all the things calmly and share your fixes so others can do the same.
I always check compression on everything even though it runs. Then hook a timing light and watch for spark not flashing while it is running. Then lastly get a ultrasonic cleaner and a can of gunk carburetor and parts cleaner and put one of the carbs in a plastic zip lock bag and put carb cleaner in the bag with the carb and put it in the ultrasonic cleaner with some hot water around the bag. Let it clean for about 2 hours and it will come out shiny like new. K+N pod filters will need to be re jetted or it will be too lean on the pilot jet. Best to find a drop in K+N for the original airbox. eBay has cheap kits for carbs if you need o rings or gaskets. The jets that come in those kits are garbage and throw them out they won't run right half the time. Your original jets should clean up fine and look like new in the cleaner. Most times I don't even use a kit. I clean and put back together they are fine. The only time I use a kit is if it leaks and you can put back together and test with a small lawnmower gas tank. I clean the needle lightly with a Scotch Brite pad and the seat with rubbing compound on a q tip in a drill lightly. Most times can have it running for the cost of a can of carb cleaner. I use Supertech carb cleaner and air to spray the gunk carb cleaner off and check all passages. Hope this helps. Any questions just ask and I will respond.
Glad you are having a crack. Welcome to the club. Keep your expectations of previous owners work to bare minimum and move on. Open the bowls let the fun begin. Prob better off without Chinese kits
