Thank you for helping to wash away the apprehension I had about taking an engine apart. Seeing someone else do it gives me confidence that I can do it too.

[@JesseWright68]

I love the way those engines sound and run, but can't deal with the flow fuel glop and mess. Thanks for the video!

I notice that your OS91 has horizontal screw mountings for the intake manifold to the head, as opposed to diagonal. I believe that may be an OS91 ver 1 surpass.
I have the same engine I acquired but it has the OS91ver2 head which has the diagonal intake mounting pattern for the screws. Unfortunately, the intake manifold for the vers 2 has a diameter of .440 in and the carb for the OS vers 1 has a inner diameter of .400in so I cannot use the vers2 intake manifold on the vers1.
What this means is I either have to change the head to a vers1 (which I cannot find anywhere) or change the carb to a vers 2.
Would you by any chance happen to have a source for the vers 1 head and valve assembly (unless the valve assembly is the same)?
Thanks in advance

At 9:45 into video, I was expecting you to show bearing below cam follower removed. Is that bearing pressed in?
If so , how is it removed (pulled out)

I am stuck with tghe same problem, how did Yiou solve it?

[@dmrcflyr2]

What particular problem are you referring to?

[@affas]

Not able to get the connecting rod off due the rod thru the piston stuck as You says in the end of this video :-)

[@dmrcflyr2]

HEAT, OIL, HEAT. It takes a lot of heat to get the piston pin out of the piston. I have numerous videos where I show the pin extraction, but I do not have the time to go find them for you.

Hey Dave I’m having a problem finding your email address. I need some help with my 91 surpass. Thanks for your response

[@dmrcflyr2]

My email address can be obtained by watching the video linked in the description of this video. I am not going to simply post my email here. Sorry.

[@mikethomas8445]

Why replace the bearings on such a low run time engine ?

[@dmrcflyr2]

Because that is exactly what the customer requested. That is why.
