What's on your bench?

[Woodslasher]

Well, a lot of head scratching later I think I found it. The carb to boot joint is leaking. So, a new boot and mounting bit will be ordered shortly.

Well, the 350 from hell is back on the bench. I wanna punch the dummy who designed the clamshell-normal cylinder hybrid. Right now I'm running in circles chasing an air leak, I think. When I got it the saw would fire right up, but it would just start screaming. I tracked the leak down to the fw side clamshell and re-sealed it. I also put in a new carb kit and a new piston, but the saw still just screams. It won't even begin to hold vacuum, but pressure only shows me I need to come up with a better system for blocking off the intake and exhaust. I thought I had a breakthrough at one point, but it turned out I'd just accidentally pushed in the decomp.

To expound upon my discovery, I made plates to block off the intake and exhaust figuring they'd do a better job than my using the carb and muffler heat shield with a piece of duct tape behind them. That fixed the exhaust leak but the intake still leaked. I checked my plate and realized it was a little wavy, so I trued it up but it still leaked. I was pretty close to tossing the saw in a corner and moving on when it hit me, the intake was the only spot that leaked! And earlier I blasted the fw side with carb cleaner and the intake region too by accident and the saw stalled! So I'm pretty hopeful that this will fix it, and even if it isn't the only leak it should fix it enough to point me to the next one.

Not much. Delivered the sw4200 and that was it. Was a bit warm on the way home from work today.

Woodslasher, your saw sounds like one of my weedeaters. I have had it for 20 years and put more than enough time and parts into it to where a sane person would have just bought a new one long ago.

Asplundh and Lewis run those small saws for slashing here. It’s not logging, mostly just brush and small stuff. They maintain the power lines/right of ways for the power company. I used to work for Asplundh and it wasn’t a fun job. Lol

Where saws go to die...

Nice front suspension and chassis mounts on that one.

Engine and pipe not mounted obviously. Just setting there.

That's how I used to do heads for hopped up street cars. The 80 grit kept the velocity down a bit while the porting added the volume.
On all out drag cars, a slightly finer grit like 120 was used. Would this hold true on all out race saws?

It's more geared toward creating a thinner boundary layer by creating small turbulence on the port walls. That reduces drag.
I use 60-80 grit on intakes, any intake system. The exhaust can be polished just like combustion chambers but 120 then some beat 150 paper and I'm done. Others will disagree but carbon covers most of it right quick if your not running alky. Polishing exhaust ports only helps remove heat a bit more by reflection imo. Pointless on the street but for giant turbo cars.

A polished surface has less area. Less surface for heat soak and more velocity to get that heat out.

Exhaust ports that is .....

@Woodslasher Closed cell foam works very good at sealing up the intake and exhaust, I normally just hold a piece over the intake with my thumb and put a piece behind the muffler.

Got some parts for my SP60 "hotsaw", a pleasant surprise showed up, and I had my brother torch the old bumper brackets off of the highboy.

Been looking for ope for my boy, for when he buys a house. I found this tractor very cheap. The fellow says, "needs a motor." I just figured I'd rebuild it.
Maybe not. Me thinks he found a new method of carburetor tuning.

looks like it met ma deuce.

It takes some real talent to achieve that kind of destruction without firearms, explosives, or a BFH.

Nothing this weekend or next week. Taking care of some things in the house plus I want to get some cleaning and organizing done. Enjoy the holiday weekend everyone.

I believe a BFH was the delicate tool used.

Gotcha, the universal carb adjustment tool.

 

[tickbitintn]

Small flat blade and some brain cells....



Or fewer cells and at least one BFH....

So on Wed the 461 Meteor piston came in, and I got that running and back to the tree guy.

But yesterday I did something more important, went up to NH to visit my new Grandson Alex! The Mustang got 24 MPG!
