The Engine from latest pesticide blower will be perfect , these engines have evolved a lot. Though i have tried one quite long back was bulky and major modifications required, but latest ones are quite very small neat and tidy. will start on single kick/pull....
Note : these are very powerful and run nonstop at full throttle for 10-12 hours for year long without any overhaul, this is my personal experience , we have couple of old and new ones at my home town for pesticide blowing.
for your ref i have attached pics..

Old model ones are very rugged and may get within 2k range... Brand - ASPEE BOLO is the best and use Kerosone only.
