I don't have such a gauge. I also don't have a fuel line pressure tester. Maybe if Colin is at Maupin and has these things, he could loan them to me. Otherwise, I'll have to take it to Kombi Haus and spend a hundred dollars to let them do it.
No, the only temperature gauge I have is for oil temp, with the sensor that replaces the drain plug. I don't think that would be very helpful. I also have one of those laser thermometers, but I'm not sure that would be of much use here, particularly since the trouble is so transient.Do you have a CHT gauge that would catch a fuel delivery issue like this? A spark issue won’t show up in a gauge but a lean out would show with higher temperatures leading up to the stutter and then subsiding when the fuel delivery returns to homeostasis.
