Dread Pirate Westley Intervention Needed

I'd clean the cap and run some carb cleaner through the tank.

Small motor experts: my lawn mower runs for about 90 seconds then dies.

Try running it w/out the gas cap. Does the behavior change?

So it would start to die out, and then kind of rev up again, die, rev up, etc

Sounds like it is starved for gas. Clean carb.

Will it stay running if you keep the choke open?

Not sure how to do that. It has an “auto choke system”.
