The pics you posted look more like Changfa types to me, TBH. The newish Blackstone engines of Indian origin (aka the "Redstones") tend to be more brick like, as I recall.
Still - would be interest to see pics & specs (you're in the wrong country for me to be interested in one...)
Pics and specs may happen, but not on this site.
PhunniPharm, then why even bother posting here?
What do you want?
What is your motive posting here?
Has any member seen or bought any of the engines PhunniPharm claims to have, and wants to sell?
Did any member go to his so called residence in Montana and confirm that this person is legit?
Members, especially new ones, just be careful.
