After having the initial trouble of will not start or run due to a oil soaked air filter--Vevor reluctantly refunded me enough money to buy one locally (after a few back and forth conversations) what happens is in shipping the compactors are being turned with the engine not upright-this is allowing the residual oil to run out the carb and soak the air filter element--this does not allow the engine to get any air !!
Now as to the quality of the compactor I can say after several hours of use it is just as solid and works just as good as most american made ones I've used, maybe not quite as heavy as some but adding a sack of concrete on top will easily make it the heaviest one !
One bit of advice--run it for a couple of hours and then change the oil--you will see lots of fine metal particles in the oil looking at it in the sun--this is normal for breaking in one of these motors and you want to get it out of there before it does shorten the life of the engine, also at this time check all bolts for tightness, and I use the top handle a lot so I added a flat bar brace from the handle to a engine bolt to make it way stronger, this helps stop the vibration from breaking it also
