Good engine. Keep it loaded or it cokes up. Pretty simple to remove heads
and de-coke. Loud as all get out, and exhaust is only part of the noise.
Much of it is mechanical. Vibrates like a bugger, so cushion it or your
dishes will rattle in your cupboards. Drinks a gallon an hour. Weighs 2000
lbs. so have help moving it. Got mine from affordablepower.com for $2100
I put 6000 hours on used fryer oil on mine before trading it. Now have a 6hp
listeroid which is a better match for my application (battery charging) and
uses 1/4 the fuel.
