Default Mephisto .21 Murnan - Part Needed

Hello folks looking to see if someone could direct me to the correct person or business that would be stocking parts for this engine? All I currently need at this time is the part that slides over the motor shaft and when the flywheel is slid on this part is pinched closed and it holds the flywheel in place. I apologize for not knowing the correct name of this part. The paper that came in the box with the engine that shows a blown up image of the engine shows this part I need as Part # 20000.

Thank you in advance for any help that can be sent my way.

These cones are pretty standard so go to your LHS and see if they have one. If you have an old engine you can use that one.

Hey there thanks for the reply......unfortunately I donít have an LHS. Iím completely forced to buy online. Also, I do not have an engine that is not currently being used. All the engines I have are installed in vehicles. What is the proper name of this part so I can ri some searches for it?

Thanks for the help!

Hi everyone,

I ran the MM R2105 this weekend. Very fast! It pulls real hard and hits a nice high note on the straight.

So far the fastest engine I've driven.

I ran it with 16X fuel. Now that I have 1 gallon through it, I will remove the copper shim under the head.

Thanks! My favorite combination is the 2165 (which is the bigger OS pipe) + MR02. I've tried several combinations previously and always come back to this one.. Lots of power everywhere and still very linear. Especially, you can really get throttle response at mid range.
