Hello mastermind, can you help me with some questions I am having regarding ms200t porting and decking? I finally want to make the move and start gaining the hands on experience of decking and porting an ms200t


Thank you in advance.

On a 201 tcm will removing that mini hoop in line with the main jet from plastic carb devider screw things up? Also have you tried squaring the intake v on the piston for a sharper fuel hit? Its super snappy but I feel it could have a little more torque .03 off base and band 105 125 83 begin v to 75 fuel. Sorry to bother you but Posted a build thread but got no feedback.

Hello sir, just getting into my second 201t and I was wondering if the c domed piston would work on an flathead 201 with some angulated chamber cutting? Seems like a potential for a lot more compression?

Hello. Have a question, have a 550 Mark 1 head back crankshaft bearings didn't realize that Mark 2 rod was different bought Mark 2 crankshaft kit. Put it together and obviously the rod hits the cylinder. Question, what a mark to piston and cylinder fit on a Mark 1 case?

Hello, do you port saws that are not new? I have a 661 that’s a year old that I’m looking to get a good work saw port job. Thanks.

It wanted to post in the classifieds and it says I don't have sufficient privileges to post. What do I need to do to post an ad?

Do you have a modified carburetor for a 3120. I don't want the epa one. I heard you might have one.

Have a ported 372 xp oe (courtesy of mastermind)on the way in a month or two . Does anyone know the model # for a 24" and 20" stihl bar for that saw? I'd like to try and find a resource that matches what you are looking .

I have a 3120 with a 272 coil, and Two 3/4" exhaust outlets. when its 80+ degrees out, after running it acts like its leaning out, turned the idle screw in and the low side out. Doesnt seem make any difference. I am thinking due to the increased exhaust flow ( no more sniffle snorkle) there is more induction, and needs more fuel. I would appreciate your thoughts on the subject.

Howdy Randy, I'm looking for a Discontinued Dolmar Coil 181-143-210 for a 5105S. Do you that 166 (Scott) is my best shot.

Mr R, what's procedure to reset computer on a ms 261m. Starts fine, runs fine but mine all sudden started very high idle after starting hitting throttle. I started on choke for 90/100 seconds but its still running away. Its very dangerous to operate as is

I need two piston cylinder kits for a ms461. Do you have anything on your shelf you could send my way?

Hey Randy! It's Steve from up here in western massachusetts, just wanted to say hello!

Happy early birthday Randy! TY for all u do!

Randy, what is your address so i can send my ms 462cm to you? It is brand new and i would like you to mod the intake and exhaust , advance the timing and port and polish as you see fit also increase compression. Thanks

Hey Randy. My name is Ryan Ratkowski. I might be purchasing a saw from Will who is a friend of yours.
I'm looking at picking up his ms462c. I was hoping you would be willing to port the saw for me as Will thought you might be willing to port it knowing that it is a well taken care of.
Please let me know if this would work for you and thank you for your time it is much appreciated.

Randy,
Could you let me know did you received 572xp, outer spike, and extra air filter from Dan (shipment came from Greece) OK?
Thank you, Henry Fuller (Chip flying)

Read one of your posts about the Stihl 064 cutting a second keyway in the flywheel. Is the something you do?
