- First Holzfforma kit I've built. MS 440 parts kit with 52mm Big bore cylinder.
Ex 98, In 78, Trans 115, squish 0.022 in, piston windows opened and piston lightened from 77.7g to 76.4g just from opening windows, cleaning flash and rounding the skirt corners.
Looks like the 440 bb will do the work of a 460. Nice resonance from the combo port and muffler work.
I'm sure it will..... After a tank or two I will lean her out and let it rip! Thanks for commenting
Nice. I built the 660 farmertec. The 440 is next. These things are a lot of fun to put together.
Thanks.... Yes building these kits gets addictive! I want to build the 660 and 361 kits and I also want to get a 260....the orange grey saws on amazon look good
How is your 660 running?
@@jarrodskeete52 Runs awesome!
Were any modifications needed to make thw BB kit fit the 440 frame?
Nope... Its a direct bolt on
11 months in, how is this one running? Do you use it as a tool, such as for bucking for firewood? 440 is up soon in my build list.
It's working well but doesn't see alot of use.... Mostly a play saw for Now......i ordered a Squish cutting mandrel so may go back in to cut Squish and lower the exhaust roof.... Set at 98 stock so not as torquey as I want.... I think with more compression and a 102 roof will pull better
@@jarrodskeete52I’m getting ready to try out cutting squish band on a 42.5mm ms250 clamshell motor by using 3M90 and sand paper on an old piston, the eBay cylinders on these have .047 squish and an exhaust roof of ~92, way too high. Have managed to lower squish in the clamshell by cutting the bearing and seal pockets, now I want to go a step further and “fix” the exhaust timing, then drop it further. I don’t know why they cast these with such high roofs. Best of luck to you, hope to see updates here. Like I said, I’m looking to build a 440/460 hybrid for this coming year.
Does not sound right
Junk will not hold up. Cheap parts
