[Mgs] [MG-MGB] Rough Running

[Dan DiBiase]

Tom, I did replace the filter element last year (OEM style)... The old one actually had been attacked by something as it was a bit torn up....!

Dan, try removing your air filters and see what happens. I had an issue on an old mini a few months which would not run right at all. It had a high flow K&N air filter on it which was basically blocked. The engine was effectively running too rich due to the lack of air. The owner of the mini then confessed that he had never cleaned the filter in the time he had the car. Some 15 years perhaps. When you removed the vacuum pipe and the engine ran better you would have leaned out the mixture by introducing air at the manifold. Regards TomAH 3000 BJ8MG MGA 1600 MKIMini Park Lane Ok, tried removing the brake booster vacuum hose with no change..... I removed it at the manifold end as it was a lot easier to get to - plugged the port there. Car ran the same when started, however revs increased noticeably when I removed theplug while the car was running. Still ran roughly but not quite as badly and with increased vigor, it seemed to me. And the hose was completely dry as far up as I could reach witha swab. I then hooked it up, ran the car again, and then checked inside the hose again - still dry..... I'll worry about the brake fluid loss once I get the car up and running again.... Didn't seem like the reservoir was any lower today after running the car a bit yesterday.... Any thoughts on what to check next? Thx, Dan From: PaulHunt73 via Mgs <mgs at autox.team.net>
