066/394 hybrid build

[Chainsaw Jim]

Muffler design??

What muffler you got on there Jim

It's a regular 394 muffler with a basic mod and single port. bolted directly on without changing the angle. That's why it sticks way up in my face. I built a bracket to allow it to attach to the two lower mount bosses for stabilization.
I have an fmf fatty expansion chamber for it.

 

[Chainsaw Jim]

What are you using for bolts to hold your muffler on now?

The factory shank bolts meant for it. Then I built a bracket to fasten the front to the two mounting holes in the case.

Then what do you use to mount a pipe? I have never been around a pipe saw.

A flange must be fabricated whether it's for matching the existing connection on the pipe or making your own to match the cylinder on the saw and welding it to the pipe.

I have the squish band all flattened out and ready for the jug to be lowered. I'm only lowering it to compensate for the squish band cut.

It still looks like a hemi to me .

I'm sitting here watching the rain, waiting for it to stop so I can go run this thing again. It seems to have woke up really pissed off but still needs to see some wood before I can say it's a success.

Is the rain gonna stop!!?? Lol. Got asked to work today, earlier this week. Dug holes for light pole bases, and poured concrete today. Now I'm waiting on the concrete to set up before I can finish them..the rain is. It making it easy!!

 

[Chainsaw Jim]

It's coming along quite nicely. Now I'm on the search for the right carb and I'm pretty sure it's gonna want an RWJ. the carb on it in the video is from my 064 pipe saw and it runs absolutely perfect on that saw but not so perfect on this build.

394 carb?

Cable might be a pain in the ass though

It's not that bad of a switch to the wj39. You flip it over and swap out the shafts and pump side cover plate. The impulse hole on the carb usually gets plugged by the boot seal as it is tightened down. The same with the RWJ, which I prefer because it's basically a bored out wj39.

I thought RWJ was a 372 carb?

Yes it is, but you have to modify a wj39 to get it to perform as good as an rwj.

 

[Frank bierce]

You find another carb for this yet?

 

[Chainsaw Jim]

It's been on the back burner until I get my requested projects done. I just finished tightening down the last bolt on Don's 505 about fifteen minutes ago. Another late night. I'll have time to tinker with it after that. I'm thinking RWJ on the carb.

 

[Frank bierce]

Requested projects!!??

Was quite an interesting build and hadn't seen it on the front page for a while...had to go find it. Lol.

 

[Chainsaw Jim]

I could have said customer builds but they're friends not customers. lol
I got this thing back on the bench today to mod up an RWJ carb for it and put the ignition timing in a better place. It now runs like I was intending it to. I'm gonna need to borrow my balls back from my ol lady to run this thing. hehehe.
So apparently ugly Betty had an uglier sister Agnes.

The top cover is kind of on there like a football helmet chin strap. It'll look much nicer when it gets the pipe fit up for it.

 

[Chainsaw Jim]

I was able to get a few cuts done with it today.

I sure can't wait to get a fat belly race bar and the pipe on it. This is the pipe I'm using:

I wonder how it would do as a work saw?

I think it would be more practical to port a big bore kit for that purpose. I'm thinking about ordering one to see how it compares to this.
