Hi Ruth and Arnold<br><br>Last year I purchased a
SM#6 wich I have since sold to Bob. During the sea
trial the engine would not rev above 2100 rpms. The
problem was diagnosed as faulty injectors. They were
changed and the engine has been fine since then. However,
there could be other less expensive causes this is what
worked for me.<br><br>Thanks<br><br>Vito Ciaravino
