You need a sponge air filter. Easy to fit.
Use ordinary unleaded petrol with no oil in it.

Snap, my sp480t has just started missing beats, lost all power & exhaust smoking, plug sutty black too. A press on the primer while it was chugging did not pick it up, made it worse.
Must be too rich, not a speck of muck in the main jet.
This is why I'm looking on the net.
I had a look at the carb & the only thing i could see on a quick inspection was a rubbery gasket that has a baggy area with a spring loading the top. Prob a diaphragm, two other small flaps that look like valves, & a bit twisted. Replacing this is going to be my first step. It sounds like a common fault so people familiar with the eng. will know how to fix it.
Any offerers?

You don't need to add oil to the petrol. It's a 4 stroke Briggs and Stratton engine.
