Would that be a FIAt or Mclaren 4 stroke perhaps?
But obviously your perspective is different, we now run a Subaru 4 stroke on a Rotax chassis, the engine is sealed and requires only regular oil changes during a seasons racing. It always starts and is within a knats of all the other subaru on the grid.
We also run a 85cc IAME Puma, this requires selection of carbs to get anywhere near (seconds not tenths) the pace. Carbs need rebuilding every weekend and even then they often go down, there is rarely a race that doesn't have 2 or 3 formation laps to allow all those whose engines wouldn't start to catch up.
The bottom line is, IMO, to be competitive in 2 strokes you need to be one of 3 things, either a karting professional or have enough money to be professionally backed, or you need to be one of the dieing breed who can do it themselves.
There was a time when many people could turn there hand to tinkering with engines, but lets face it even motorcyclists nowadays don't.
Most people nowadays just want to get in and drive, the Rotax 'EXPERIMENT' tried to address this but has patently failed and ultimately only a 4 stroke engine is going to do it.
