bought this recently with a bunch of other parts for 15. manufacture date of 10-15 so it's not old, very clean and has great compression. Can anybody tell me exactly what this is? Looks similar to a huasheng 49cc. carb was missing primer so i need a new one. any suggestions? the pull start is broke too but I have a couple that fit.
