First I want to say that I am embarrassed that I can't even DAYDREAM that much work. You have inspired me...at least to do something mediocre so I don't feel so useless.
Second, You will be very happy with that Suzuki DF140. Plenty of power, no blue smoke, and so quiet that you will try to start it while its running! And you turn the key and it starts, every time, and it keeps running and doesn't sputter out...even 5 years after you got it...and you smile and say "I love that motor".
