What's on your bench?

[Frank bierce]

Playing with some chain...never tried it before...let’s see how bad I fug this one up. Lol. Gotta start somewhere.

 

[Cut4fun]

Frank those poor unknown folks just going to cry your ruining a chain.

 

[Cut4fun]

Put the min together on PP445 #4 and she now is a runner. Sounds good.
Now to get all the missing pieces and put it together completely.

Did have a bad used ngk plug on bench I had to toss. It would just shut off like you flicked a switch off. Put another in it and ran fine idling etc forever. When I get her done a new Brazil or German bosch will go in.

This 445 I think I may try a metal worm gear in to test and see if we can backwards engineer them from the plastic worm gear. I have it ready to try someday.

Plus won...looks like it needs a clutch? Pix are blurry

It will work if needed it looks like.

Didnt cut with it because both saws still project stage.

Started and started to oil. Saw hadnt oiled since I got it as project as it wasnt all there. So it works.

Took this in on trade, has the original
30" bar the guy bought it with. He decided it was too heavy and didn't use it much.




No decompression valve here.

6401 gettin the 7910 treatment. Came from a box of chit that’s missin a bunch of stuff. Finally gettin around to puttin it together so I can make out a list of parts.

 

[Deets066]

Good thing I got a few refrences. Lol

 

[MG porting]

I dropped it down to 13800. Well it runs and runs pretty darn good with the port timing numbers I gave it what's you all think. Lol.

Need to see it in some wood. Likely, after break in, a lot of them like some more RPMs.

Some of them don't really feel strong in the cut till you lean them out a bit, but I know you want it a bit rich for break in.

Yea i got a feeling that this will spank the 044 I built and it was and still is one saw I wish I never sold. Lol

 

[MustangMike]

Hey, I recently sold a real nice low hour 440 that ran great, I'll just replace it with a Asian BB that runs a little stronger!

Lol. That's funny!! I built a big bore ms440 last year it was OK but it just didn't get me all that excited I was hoping it would be as good as my 044 but it was lacking something so I sold that one without regret but the dang thing still runs.

They need port work to run right. With the New West BB kits I lowered the intake, installed bridge ports, (BB cylinders often have thinner transfers), and opened the exhaust a good amount. Also, moved the upper transfer openings to be in line with the lowers on the intake side (they were a bit short). It runs very well, and has decomp.

The NW BB jugs have nice D chamber combustion chambers. I like em!

The big bore I used was a farmertec I did a little bit of port work on it but I didn't give it bridge ports or give it more compression witch maybe the reasons why it wasn't as strong as it could have been but who knows I may do a big bore on the next one but do it the right way. Lol

That is an insanely good deal!

Got a 193t on the bench. It's a tree service saw and they said it had no power and died in the cut. It felt it had no compression but it started. Here's what I found so far...
