In 21 years of ownership of my 1999 26X I have probably cleaned the carbs 10 times, replacing gaskets regularly but the jets only a few times.
I always had success immediately, but this season there is a feeling that things are not quite right.
There are at least a dozen things to check when the old Honda ain’t right and I did all those. I want to adjust the carburetor synchronization for the first time. And I am too cheap to buy a three gage vacuum set. So, in the next week or so I will try two methods that I will mention here. I will post results later.
Method 1. I will remove the carb intake shroud and start the engine and after warmup I will place a 1/4” piece of tubing at my ear and listen to the intake whoosh sound at each of the three carb intakes and then adjust number 2 and 3 to match number 1. I learned this procedure in my classic British car club in tuning SU carbs.
Method 2. Having in my shop a single accurate vacuum gage and lots of various 1/4” fittings and tubing, I have come up with a plan that uses the single gage connected to all three carb test ports and utilize the easy crimping of the soft tubing to look at a single carb at a time. (Pic at bottom)
Comments welcome. Results in a week or so depending on my schedule.
Ps- yes, the male “NF” die threads I used do not perfectly match the female metric threads in the test ports, but close enough, a tiny bit loose, so I plan on a bit of teflon tape on the threads.
