speedy amazing you got it running again in dat condition
do you know history was it run without oil in fuel, I worked on a lot like thatover years in shop we would rebore new piston ring ect
norm may be you need to do preasure test crank case to test seals,they do this on most 2 stroke motor bike engines before and after rebuild , leak down test to check for air leak at seals
seal leak make motor running lean
