I have been working on this motor for a while and I am not giving up. I had a problem with warped carb bowls and carbs. Sanded the bowls flat and new gaskets. Pumped ball and believe they are sealed. The ball was still stiff a few days later and no signs of fuel weeping out by the gasket. I finally took it for a spin. It started up and idled real smooth and easy. It was pretty quiet. It runs as perfect as I believe an old 2 stroke looper can up until 3k. If I push it past there It starts surging. I can get a whole shot and hit 5k, then it starts surging. I had rebuilt the VRO pump last year because it wouldnt go past 2k. I just replaced the pulse limiter( with blue one). I also replaced the larger fuel lines to pump, limiter, carb distribution T, and fuel tank. The primer ball is also a new style one from a year ago. I am running off of a 6 gallon tank with pre mix.
I apologize for the shaky video but it was really rough out.
