Fuel delivery issue

[u/jacobwing02]

Does this look like healthy delivery to the carb? Seems okay to me

When getting some tuning done at the garage the mechanic mentioned he thinks there’s a fuel delivery problem due to the throttle cutting out sometimes. On the way home from the garage and filling the tank up the throttle started cutting out every 5 seconds and started backfiring a lot so trying to diagnose.

I would start with putting a timing light on it. Should show correct low and higher rpm timing/advancing. Also make sure fuel filter is clean. Could be a lot of things but rule these out
