I still need to fix the weak rear spark on mine, but it currently holds enough power to easily handle the house lawn (take it to the longer stuff down the back and its over).
That said, no, and once it is completely healthy, probably not, its nice for an occasional use, but I have a 1973 VC-160 Auto Drive, and if you have self propelled, why not use it.
If i ever do take the twin into regular use, i'll let you know how that goes.
