And now for something completely different.

well, not really, this has all been done before. but since none of you guys build saws and you only use this forum for entertainment, i thought i should do a thread on this saw.
starting out with a saw that @cuinrearview dubbed the weed whip, due to it having been assembled with crank stuffers from a husky trimmer. see his build thread here on assembly and fitment of the stuffers:

346 stuffers

There was a thread here from before I joined without a lot of info. It seems like a straightforward concept so I had planned on building this with a few pics and a vid and reporting on the results. I started into it this morning and thought i should share what i found and gather thoughts. I...

when i saw this thread i thought this could be a cool thing for a play/race saw. problem is the “cups” are backordered from husky for a while and i wanted to get workin on a 3 cube so tim and i made a trade and i got a good solid saw with the stuffers installed. no before pics of the stock carb/intake etc…you can use ur imagination. this is where we are headed…

tim put this saw together with a cylinder that he got with some other stuff, seems as though somebody started port work and didnt finish. exhaust and intake and lowers had been dikked with, uppers were not touched yet. we ran this saw a couple years ago, it was really high strung, like would rev to the moon and fall on its face in the wood immediately. @huskihl cut as much as he could from base and squish without making a big flatspot on bottom of intake. we ran this saw again a little bit at @Fifelaker house this winter. it was better, more torque, but still tended to lose tons of rpm in the crust.

here are some pics of cylinder as it came off

we didnt time it prior to machine work, but after machine work ex-103, trans 132-134, intake 81.

This thread reminds me that I promised to send Tim a new hoof rasp and a longer base for his orbital sander.

oh boy, just wait….

 

[cus_deluxe]

carb being used is a walbro ws-10. i picked it for a few reasons: A) i had a couple on hand. 2)in my limited experience they seem to deliver plenty of fuel and tune nicely. D) its bolt pattern fit the 390xp boot i wanted to use.

 

[cus_deluxe]

since exhaust and intake had plenty of duration to get goin, transfers were where i spent time. cut some card stock after some measuring, should get me around 125-127. probably still too much blowdown for a small quadport with stuffers but easier to grind out than to add it back later. i got rid of some of the mickey mouse ears on (bottom) of ex port…and smoothed things out.

Orbitals are for amateurs real builders use a belt sander sheesh… Don’t you have some cargo pants to model or something?

 

[cus_deluxe]

just a look at how much transfers had to come up to even get in the neighborhood.

 

[cus_deluxe]

since transfers had to come up a long way i tried hard to keep the port within the original bevels, which actually seemed really excessive.
anybody that grinds on these and thinks their work looks rad, then takes a picture, knows how hard it is to take glamour shots of uppers. these were pretty rough from the factory in my opinion.

more transfer work:
182mc did the majority, but a big thanks to @srcarr52 for making these handy little buggers available to us forum guys. makes a huge difference being able to get back around corners and stuffs.

 

[cus_deluxe]

this is where i ended up with uppers for now. tried hard to keep primary side as flat as i could, gave secondary side as much upward angle as i could.

 

[cus_deluxe]

now, imagine the most disorganized m-fer u ever met. then try to imagine who would be in the hall of fame of disorganized people. id be right up there, so a lot of the pics im posting are not being posted in the order in which they were taken. just fyi.

 

[redline4]

Never fear, I'm here now.


How can I assist?

 

[cus_deluxe]

ok, so, the 390xp boot fits nicely on the 346 intake flange, the biggest issue is…

 

[cus_deluxe]

so we grind, and honestly, this intake setup is actually going to have a slight upslope as it enters cylinder. not ideal? probably. got no choice? definitely. but honestly, the way i see it, with the stuffers theres not a whole lot of room to send that fresh charge down the case anyway so it might as well follow the piston up…

 

[beaglebriar]

Are you gonna turn a 572 piston down with an inverted pop up and vortex stratos?

a little of our favorite 2 part epoxy and some masking tape. i always like to give it some gentle heat to loosen the epoxy, helps air bubbles to make their way out.
