Carburetor is not included due to so many different model choices available on eBay.  We Recommend the Mikuni VM18, PZ19 or the VM21 carb.

 Regardless as to what some people may say YuanDong is the exclusive CHINESE manufacture of the Avenger engine.  It's the same factory that has always made our SkyHawk line of 2 stroke engines for over 21 years.    Look for the YD logo on the crankcase to ensure authenticity.  Other Chinese factories will soon learn to copy the YD Avenger 85 design so beware of fakes.

My Wife's retired brother inspects at the factory what you expect and yes that's not 100% perfect but it's a lot better than no inspection at all when you consider piece worker's pay is the same for making defects as it is for making zero defects.    

NOTE:  If any USA DEALERS or Avenger 85 Wannabee dealers wish to place an order for 100 or more with or without OCDT we can quote factory direct wholesale prices , via our Chinese trading company Changzhou China GAS.   (yes, same price Gru-Bee pays as China GAS gets the 10% VAT tax returned by Gov. as their profit).
