Happy Monday friends, it was a bit of a cool weekend here but I did get some time with the Midget.
Some of you will recall that I have really struggled for a year now to get it running right. Last fall I removed the plugs only to find them completely sooted up, I bought new ones - and they sooted up in about 4 blocks of driving. So, too rich. Turned the nut anti-clockwise (from top) on SU two flats. (BTW I have a single HS4 MGB SU) - still sooty. Another flat and a half and finally the plugs seem a better colour. My question is simple - how can it have fallen out of tune so much? The nut was tight enough to need a wrench so it can't have vibrated. Yes, I currently have the air cleaner off - but to my mind that could only make it leaner. So, what could make the car run so rich all of a sudden? Oh, and I believe the choke is properly turning off.
thoughts? thanks all!
