The bus limped home yesterday when coming home from work. The 2 year old gremlin struck with a vengeance. I tried shutting off the motor and checking spark in all cylinders. Nothing made it run right this time. So I just left for home about 22 miles. I made it without issue but the power of the motor was way down. I needed to pull the motor to see if I could find anything in the ignition or carburetor systems. So I took Friday off work even though I really needed to work but no car so what are you going to do.
I pulled the motor then removed the spark plugs. I found the #1 spark plug seemed gas fouled as it appeared wet but was not wet. It had a glazed look to it. I also found the spark plug (#2) with the CHT sender under it was leaking. I replaced the glazed plug and moved the CHT to the #3 spark plug and hopefully it will seal better there.
I also removed the tops of the carbs and remeasured the float positions. The left side upper position was correct but the drop position was too much (about 15mm). So I adjusted it to about 12mm. The right side seemed out in both positions. I adjusted them into the proper positions of about 5mm and 12mm. But I also found a clip that holds the float in the bottom of the bowl. This may have been the 2 year old gremlin giving me issues intermittently. So I will reinstall the motor today and we will see if I indeed fixed the gremlin.
