OK, dont laugh, not exactly a "car" but at least carb related.
I picked up a 96 craftsman riding lawn mower, free. It had been sitting for years but ran fine before.
It has a 15.5 hp Briggs and Stratton with a Walbro LMG carb that was gunked up. I rebuilt the carb, cleaned all the passages, and replaced the float, needle/seat, jets, etc. and it started righ up. Idles great, responds to the idle air screw, throttles up fine and runs smooth. But even a light load at full throttle will bog it down and kill it (engaging the drive belt even in neutral).
All the belt rotate easily and it will backfire when it bogs, so I'm thinking the main jet is lean. There's no adjustment and no optional jets that I know of. The governor also seems to be working fine and will try to throttle up when it bogs.
I've rebuilt Q jets, Carters, Holleys, even Webers and this Walbro is about the simplest I've seen. Anything I could have screwed up???????
