I wanted to post some pics of the latest saw I got thanks to member Halfscale. It is a Strunk Big Timber Pro. It is a 95cc saw and it runs. It is a 30" bar on it. I took the pics with my phone and am using my phone right now to post them. I will post more later from the computer.

Collector item for sure.
At your right thumb, is a chain oiler pump. What is the other knob?

I am not sure, I will mess with it more tonight and let you know. I was able to get it running but I couldn't get it above 1/4 throttle, it was definitely running too rich. There is a numbered dial on the side of the carb. I did try turning that in to lean it out but it didn't seem to have an affect on it. The chain has some life left in it so I will sharpen it and get it running good and cut a piece of log with it. I know I wouldn't want to tote that thing in the woods all day. It is right around 30 pounds.

I took two quick videos of the saw today after work. One is to show it running basically without doing anything with it. Although I did pull the carb off to clean all the gunk off the outside of it. It was running way too rich at this time:


I pulled the stop off the carb for the high speed needle because I wanted to see where it was set at. The high speed needle was set at about 3 1/2 to 4 turns out which I know is way too rich. I am surprised it even ran. So I set the needle at 1 1/2 turns out and left the stop off so I could mess with it some more. I don't want to go any leaner on it though until I get the oiler fixed and get the bar and chain on and get it buried in some wood.

Here is the second video, you can tell it is running a little better:

I jb welded the oiler last night and let it set overnight. I put the saw back together tonight and drained the gas out of the tank. The tank has a petcock on it. I pulled the fuel line off the carb and opened the petcock and no gas would drain. So I pulled the cap off of the tank and the gas started flowing but it wasn't as fast as I thought it should be. I figured maybe since the carb has a fuel pump the speed it was draining would be alright with not have the suction from the fuel pump. I thought about the fuel cap vent being plugged up but I kind of thought in the same regards with that and the fuel pump so I left it go.

I was going to sharpen the chain too before I was going to try it out cutting wood but I was too impatient and carried it up to the wood pile. It cuts wood, although the chain needs work. I will sharpen it correctly tomorrow and get some video. I do however need to check that fuel cap vent, when I was in the cut the saw leaned out on me. I pulled it out of the cut and let it idle and then went to cut again and it would cut for a little bit and then it leaned out again so I shut it off for the night. Even with hearing protection that thing has my ears ringing. I also realized how much out of shape I am carrying it about 100 yards up and 100 yards back. With the bar and chain on it, it weighs just under 40 lbs.

I got the Strunk running good enough to cut wood with. I need to redo the oiler though as the jb weld isn't holding and the oiler is leaking big time. I hate to replace the oiler with something else but I might have to. Either that or never use the saw but the thing is too much fun.

Here is a video bucking a short log and doing some noodling. I did have a little trouble with the saw when I was noodling, I pulled the saw out to kick away some of the noodles on the backside so I could see what I was doing and it stalled on me. I richened it up just a tad on the low end and increased the idle rpm just a tad and she started right back up. I will tinker with it some more once I figure out what I am going to do with the oiler.

hmmm, yeah. those were the biggest pieces of crap ever to be released to the public.
you should be far more than embarrased to even have that thing on your property.:poke:
i can't even partially believe you would post pics and admit you have (or even bought) it.:laughingteeth:
those strunks were a cool saw! i have no idea why they didn't hang around longer than they did. they had some really good units and the one you have is no exception!
AND you have the clutch cover! really cool mang!:worshippy1: they have a great sound too.
i can't wait to get my grubbie little mitts on one for the display shelf:bounce:
