Best source for hard to find parts
I had been looking for a year to find a mower fuel gasket without success. One call and instant access. Great job, perfect timing and really nice to work with. Highly appreciated.

Sent wrong part.
Part came in 3 days, however they sent the wrong part.. The invoice had right part# 1204105-S. But part 1204109-S was sent. Had a snow storm coming so wound up driving to engine repair shop and get right part myself. Not sure if this happens often but I think I'll try a different site next time

Gas leak under the bowl.

Parts Used
1. Took off the gas line and just secured that in the up position.
2. Unhooked the wire connection from the where the two wires were connected (did not disconnect from the bottom of the solenoid).
3. Unscrewed the solenoid from the bowl. The bowl will come off with it.
4. Replaced the seal around the bowl (rubber) and the seal on the solenoid (makes me think of a saw disc) between it and the bottom of the bowl.
5. Fitted the bowl back to gently seat it over the seal, then screwed in the solenoid. Hand tight then used a wrench for a slight 1/8 more turn.
6. Attached the gas line back. CHECK FOR LEAKS.
7. Re-connected the wires.
8. Turn on, check for leaks, run around the yard. Using with and without the blades spinning. Check for leaks.
9. If no leaks you are done. If you see something, make sure you did not pinch or bunch up the rubber seal at the top of the bowl.
