2. snapped sensor, where can i get this part



3. needs new o ring seal and plastic housing as it brittle and uneven, the one on the side of the block below what i presume is the oil pressure sensor just below my fingers. where to buy



4. the auto choke is disconnected  is this ok and if not what can i do
