Mower: Snapper 7800190 (the Walmart special I think, it’s second hand)
Mfg. No: 7800190 SPV22675HW, 22" 6.75GT Variable Speed High Wheel Mower
This model has “Auto choke system
Engine: B&S 126T02-0675-B3
I bought this second hand years ago, no start. Cleaned the fuel system and carburetor. Ran for several years. I only use it to trim under some bushes on a berm where my rider can’t fit. I put it away last year (it ran fine) and didn’t need it till now.
Went to use it and no-start! Dang it. (yes fuel stabilized and put away dry)
1- Cleaned and re-gapped spark plug (it looked fine). Cleaned carb, fuel lines, new fuel, air filter and oil, still no start.
2- Replaced carburetor (cheaper than the rebuild kit I could find, jeesh what a waste)
Reassembled and it ran 1x but would not start second time. (New springs on air vane and governor).
3- Disassembled again and I found a cracked the manifold and had bad continuity on the coil
I repaired with the manifold with epoxy (a new manifold was NA or $40+), and bought and installed a new coil and spark plug.
4- The old vane did not have the clearance for the new coil, and I cut a small 1/4” section (minimal amount to fit) from the rib to allow for free movement and clearance. Thermostat arm moves freely and when it runs, it does operate.
Reassembled and it ran after a bunch of pulls and with me manually opening the choke (took off the vane spring) and pumping the throttle multiple times. After shut down, It will not reliably start.
Thanks, John

- I have compression (didn’t actually measure it yet), I have spark, I suspect something with fuel and air. (I haven’t used ether yet)
- What is the proceeded to adjust the thermostat? Is a new air vane required or even going to fit?
- What am I missing, any other suggestions?
Thanks, John
