the pin (***) on the crankshaft that holds the bottom of the conrod is longer on pullstart version.
Just want to clarify this statement. This statement is not true for this engine. (Hyper .21 8 port)
I have asked rc shops local and online - some said that crankshaft is the same for ps and non-ps and some said they are the same.
I just got a response from OFNA tech support and told me that they are the same.
