Small engine repair thread
Got a lawn mower, Briggs and Stratton, push mower (self propelled but the self don't propel anymore). Thing ran fine, then starting revving up and down for a while, then got to where it wouldn't start and stay running. It would start, rev up and down repeatedly, then die, then refuse to start until it had napped for several hours.
Took air filter off, drained fuel, took carb off, opened it up, stared at it, put it back together, put the drained fuel back in, left the air filter off. Started like a champ and ran great for several weeks, then started acting up again.
Drained fuel again, retried, but still won't start and stay running. Choke opens and shuts (causes revving), if I hold it closed she revs and runs fine, but I let go of the flap and it opens and starts choking out till it dies.
Went to repair shop, wanted to buy new carb (figured it would be 20 bux or so?) but guy said it would be cheaper to have him repair it than for me to buy and replace carb.
Hmm. Riiiiight.
So... troubleshooting checklist? What's my next step?
