Took apart my Walbro carb on a 15-year-old OHV Briggs engine, 17 hp, in my Craftsman tractor, cleaned it out (but didn't change any parts), put it back together, and it's leaking. Candidates: the float valve or the seal on the electrical fuel shutoff? Any thoughts (especially if it's the fuel shutoff?)
Also, for this model carb, there seems to be only a $14 minor rebuild kit available (on eBay), which only has a few parts (search for: LMT-WALBRO-REPAIR-KIT-BRIGGS). But there are plenty of new carbs available for around $20 (not OEM, of course -- finest Chinese replicas). Any experience with those? My carb has the following numbers: 4993, LMT, 67
The engine is running, but only w/ at least half choke, and lots of backfiring. However, I think most of my (original) problem (backfiring on shutdown and constant surging) was caused by never-adjusted valves and/or a never-decarbonized head. Both of those will be my next step.
All comments appreciated
