Gets stuck when the carburetor is set.
For now, it looks good. Check the spark plug color.
Only cylinder 4 is fouled.
Oh no.
Try swapping the coil wires for cylinders 1 and 4.
No change.
Check the actual fuel level.
No problem.
Check the float valve.
No problem.
Lean out cylinder 4 only and check.
No change.
Hmm.
Check the synchronization. For some reason, cylinders 1 and 4 won’t adjust at all.
Oh dear.
Disassemble and check around the V-block.
Wash and reassemble, but no change.
Yikes.
Should we replace the seals?
What am I doing? It’s already this late… sigh.
