I don't know about a V2 version, but I just had my SAP 180 upgraded with a new carb and the new muffler. Turnaround was rapid and the cost was only parts and shipping. At one time this was one of the first motors that were produced, but it has been upgraded to current standards. Last year my carb started acting funny and I replaced internal gaskets and diaphragms to no avail. That was after several years of flying and many gallons of fuel. The motor had been in 2 airframes during that period. It will be back in the air soon -
