Hello useful people
I made the mistake of overfilling my oil. To make matters worse I drove it around for most of the next day. I drained the excess oil and cleaned the sparkplugs but when shifting gears and driving, it feels like multiple engine misses happening in a row, bouncing me back and forth slightly in the seat

Help appreciated

 

I would put new plugs in once you get oil into your cylinder its done damage to your plug

 

How much did you overfill it by? There shouldn't be any plug fouling if your rings are good. Unless you filled the crankcase plumb full of oil. I have made that mistake and put in 1 to many qts and I just ran it that way till the next change. No harm done, the crank more than likely just sloshed around more oil that time.

 

I always overfill my 416 at least one quart.

 

Overfilled that's not good. You must of got a lot of oil in your cylinders or have worn piston rings. Since it seems to be missing now I would get a set of plugs and put them in. Hopefully the oil is all burned up now. Since it's spring and you already changed the oil and about to do the plugs mise well give er a nice tube up for the year.
