Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Craftsman LT1000 lawn tractor with Briggs & Stratton 17.5 HP engine
- Briggs & Stratton 31C707-0230-E1 lawn and garden engine applications with matching carburetor
Product Overview
An LT1000 that has been parked with untreated gasoline may crank but not start, run only with choke, surge, or leak from the carburetor bowl. After fuel flow, spark, compression, valve clearance, and the anti-backfire solenoid are checked, a replacement carburetor can be the quickest route back to mowing.
31C707-0230-E1 is an engine model/type reference—not an OEM carburetor number. Read the complete stamp on your engine and compare the carburetor flange, choke control, throttle links, fuel inlet, bowl solenoid, and gasket pattern before purchase.

- Matches the common single-cylinder 17.5 HP intake layout when verified

Compatibility Notice

Frequently Asked Questions
Q: Is 31C707-0230-E1 a carburetor part number? A: No. It identifies the Briggs & Stratton engine model and type. The carburetor still needs a visual match.
Q: Why does my LT1000 run only on choke? A: The engine may be lean from a restricted carburetor, weak fuel flow, intake leak, or tank-vent problem.
Q: Can I reuse old gasoline after installing it? A: No. Drain degraded fuel and clean the supply system to protect the replacement carburetor.
Q: Does this fit every Craftsman LT1000? A: No. LT1000 tractors used different engines. This listing is for the stated 17.5 HP Briggs configuration.
