MG Car Repair: Carb Tuning, jet adjustment, miss fire

Question
It's Jon with the 1976 Midget (1275 in it). I took the car on an extended trip today--about 30kms. The car drove ok for the most part. It was quite hot today, it bogged and bucked a bit--first 2 kms or so...after that, it went through gears ok. When you got "into it", under load, it would bog and jerk above 3300rpm. At idle, when you push the "pin lever" in and hold, the car drops in idle and kinda (as you call it) sounds like a tractor. This seems about the same on both carbs. I did, yesterday, have it set at one point when (lever pushed in) the rpms would move up for about a second and then drop--but not as low as current. It seemed to perhaps run a bit better yesterday at that setting. Can you clarify the sound with lever in--and what I am experincing under-load.

Thanks Howard.

Answer
What lever are you talking about pushing in?
A miss fire under load narrows the problem down to a million things. When the carbs are set that is the end of that, so any problems in driving are not jet adjustment problems. Be sure you have oil in the top of both carbs then look toward ignition or engine. Meaning do a compression test and go through the ignition system completely.
