i play the video to a friend who has built engines and he says it might be a fuel problem. fuel may not be getting to the cylinders at first while it turns over fast then (no smoke from the exhaust) when the fuel does get to the cylinders the compression slows the starter. (smoke starts to appear) then as the fuel starts to burn the rpms increase and it starts. it makes sense, but im not sure im sold on the idea.
