Ok so I know there are a ton of carb/flat spot diagnoses posts, I tried searching. Here's my problem. VM 34 rephased, pamco ignition stock mechanical advance. Timing is good, advance seems to work as designed. In 4th or 5th gear around 45-5000 rpms if I roll off the throttle and then back on it has a flat spot or stumble then goes right back to normal. Just curious if anyone has had a similar issue. I'm going out to clean the carbs and check the valve adjustment here shortly. Assuming that doesn't help I'm thinking start with adjusting the needles? Oh and I'll check the plugs as well. Thanks in advance.
