The large MVVS engines have increased $20.00 . They are now $179.95 for the 77.
I think they've made some design changes though. I know they've changed the
carb and the web site says the crankshaft is different also. There might be more
as the picture on Morris Hobbies web site looks different than my engines. Probably
made a good engine even better.
Mine are a couple of years old.
