    Send some snow down here to Connecticut. Hope all is well Tinman. Working on a Straight-Gassed Husky 455 Rancher with a Duke's Pop-Up Piston. Now I'll have to port the cylinder!

    Thank you for the comparison Tinman. I have a friend building a 85cc bicycle engine with the clone MS 460/380 piston combo. He recommended I also strengthen it with a pop-up and 5th transfer port. So I sent him 1 of each. HL supply and red roof or red box.

    Many late model two stroke dirt bikes come with domed pistons wonder why that hasn’t come around on saws!? Great vid!!

      I'm rebuilding a stihl 201 top handle saw that has a domed piston from factory and its a 2019 model so maybe they will start moving in that direction.

    Tinman I just bought a parts saw for the screw in gas cap for my ported 046 it's a 044 10mm wrist pin crank so I think I'm buildin a slant fin 😅😊😂

    All this, or just run the shortest bar possible.
    Forget the intake port location, it's not in the combustion chamber.
    My 034 with a short bar on 25:1 will run for 100 years.

    I put a big bore kit on my farmer G444 with base gasket delete and worker saw ported with everything I learned from you and Ironhorse. it squished at 32 so I think a pop-up piston would help me since I don’t have a mill or lathe

    It will be nice to revisit your journey. My trailer plug builds up some oxidation and then a poor connection, a little clean up and back in business or The main ground wire breaks by the hitch. TC Mahalo Tinman 🤙🤙🤙

    Thanks Tinman. That's pretty much the explanation i was suspecting. I like the what you said about sweeping the transfers. Would you do that to the primary only? I just finished up some grinding on a 353 that i bought. The cylinder was a little boogered up, but cleaned up ok. We'll see how it runs. If it's a dud I'm going to get a 346 top end kit from Ryan.

    Them diesel powered recirculating coolant heaters work awesome in heavy equipment. And they’ve come down in price quite a bit

    I'm picking up what you're putting down!! Already bought a pop-up,.013 gasket and dual port muffler. Now since it might have a little more grunt, can I go with an 8 pin sprocket, and 3/8 chain on my cs2252 and still keep my rpms in the cut ok? I'll be limbing oak with it.

    So the pop up kinda acts like a burr on one of your ports therefore making your air/fuel mix lag within its travels?

  • @fast4405

    How does the popup affect the turbulence at the time of the squish? Could a popup be beneficial to a lazy squish type of saw?

  • @EricChmelarsky

    I never knew what a pop up did. I will confirm, angle the transfers upwards. 7310 ported, thats what he did. High and midrange power is ruthless. Gasket delete and base cut. I can barely start it without decomp. Its my sleeper saw, dont look like much. Oh but she cuts.

    Tinman i just bought a 300th anniversary edition 268xp and was wondering do u think it's worth putting a 272xp top end on it? Or just do base gasket delete on the 268xp cylinder n port it?

    If all your trailer lights are flickering, check your ground probably bad or intermediate problem. Hope what helps my friend
