Picked up 2 PC Mahle 52ZK 11W5. Bought them thinking 7900 or 681. I'm thinking Dolmar 7910 SLR cylinders because the exhaust port is stepped for the tube. Didn't notice the spark plug is almost straight up and down not angled like 7900. Pistons are the old windowed pistons that the windows are cast over to make slab sided piston. You can see the windows inside the piston. Need verification on what they fit. Checked the base with cyl gasket for 7900 dead on.

Until Kevin gets more space you could upload them to something like Photo Bucket and then link them to here?

If your using the Firefox Mozilla Browser, here is an add on that doesnt take up much space and works great. All you do is right click on the pic and make it smaller in size to meet the upload requirements.

Make that 399KB per pic so confused why a small 168kb wont post? ???

Yep out of space. Time to dig in my pocket for pic space. :-X
The upload folder is full. Please try a smaller file and/or contact an administrator.

Shep give it a little bit. Just purchased some more space.
Will check the admin area and post here when I see the space show up.

Shep post the pics the space shows there now.
Guys PM me when something like this happens. Usually I get a email stating low on space. Nothing this time was sent out. :-\ :-X

Sounds like they are for a Dolmar Cut Off saw like a PC7414.

Ebay.
7414 chop saw cylinder. numbers match the one I have on the shelf. 50mm?
Yep 50mm. When I bought them I didn't think about chop saw. Good thing is I got 2 of em CHEAP. Bad news is I thought they were 52mm. Anybody ever run the timing numbers on one? Should be torque and lots of it.

they aren't that impressive. the 7414 is a very well built saw but power wise a ts420 spanks them. if I remember correctly with a blade buried in 4 inch concrete dry cutting they will hold around 7k rpms. I did some side by side comparisons of ts420, k750/k760(cant remember which it was), and 7414. rpms in the cut and the pressure you could apply while cutting the 7414 lagged way behind a ts420 and was about even with the 750/760. 7414 is 73cc. ts420 66cc. we even tried muffler mods on the 7414 to wake them up. dual port muffler mod and that slr chamber removed they gain some power but still not quite comparable to a ts420
