Sachs Dolmar Chainsaws Thread

[psuiewalsh]

Hello to all,
Sorry I didn’t reply sooner been busy around the house.
The ignitions I use are from C & H Ignition, Unfortunately the guy (Bill Carpenter) an automobile mechanic who designed & started this business many years ago has retired, what a great guy! Someone did buy his company out so you can still buy his ignitions; I have not really had any correspondence with him yet-per website can give you some in-site.

About us - CH Ignitions

http://ch-ignitions.com/index.php?id_product=28&controller=product

I will try to explain the best I can, basically what I do with the engines via ignition is chuck up the chainsaw flywheel on an old Sachs crank shaft stub in my lathe, your end product will be a disc approx 3.5” in diameter. Needless to say you must be very careful doing this!!!! You must use a live center via tool post side for stability. Gingerly you must reach in with your tool post and bit and remove the inside area right before the cooling fins, it takes time and patience, depending on the engine sometimes I remove the fins first for clearance, I try to avoid the fin remove because it raises hell, like a card in the spokes of a bicycle. I do not cut into any of the center ferrous metal crank shaft mounting area were the aluminum is casted. I keep plunging into the inside fin/ magnet area until you here the magnets and counter balance scraping the tool bit, then move in towards the center to clear magnets etc.
When all said and done on the back of this disc a small rare earth magnet is epoxy mounted into a bore, on the crank case a mounting bracket is made to hold a hall sensor. I set the ignition timing at 28 ‘ BTDC, C&H ignitions have auto retarded timing, when you flip the prop the ignition retard to 0’ auto and is linear to advance with RPM to 28’, a good primed engine will start with half a flip of the prop. The ignition box is powered by a 4 cell-4.8v DC, 1000 mah minimum AA rechargeable battery. The ignition box is approx 2.5” x 2.5”x 1.25” and now I think smaller. The Ignition has 3 leads via spark plug boot & lead around 12” long , battery lead and 3 conductor Hall sensor connector of your choice. I’ve never tried it but you can probably get around 2 hours straight running time out of a battery.
I have thought of doing the same thing to one of my saws, the only problem I see is a saw needs a full flywheel with the OEM magnets via balance, pull start dogs etc, these magnets would have to be isolated not to interrupt the hall senor, or figure out timing using the OEM magnets new Hall sensor, also having clearance to mount the sensor, it can be done just takes time to figure out. Remember I do this with the crank case cut down to nothing, you can see the photo from my post page 157 #2344 I have plenty of room to work. Someone would have to figure out where to mount the battery, ignition box, switch etc. I would make the battery easily removed for quick replacement.

It can work, like any motor- that motor don't care were the spark is coming from, only cares about at the right time.

Hope this helps, anyone feel free to discuss, PM me and I will shoot you my phone #, I'm not to good at writing these forums,

Vinny,

I wonder if you had a saw with the heated grips generator would provide a power source?

I wonder if you had a saw with the heated grips generator would provide a power source?

I am not a electronics guru--but if it's constant 4.8V DC why not? If it's more than that--- I think 6 volts max, you would need a small voltage regulator. We use them all the time not to burn up the servo's. A 3 amp regulator is about $10 to $20.

I would think any kind of heating element supply voltage would put out plenty of V/A to handle that ignition.

My method-try it and watch it smoke--I broke allot of stuff experimenting:msp_razz:

That will be a wonderful saw when complete! I hope you find your parts.

it appears finding stuff for the 166 is like pulling crocodile teeth!

You wouldn't happen to have both crank case halves, crankshaft assembly, piston assembly and cylinder for a 166?

Thanks,

I sure would like to know where your finding all
these new parts. Can't find any here in the states.
I sure could use a couple mufflers.
I can hook you up with the K&N filter but not the
whole top cover set up. The filters are still available
here from K&N.

If it's a good runner and in nice shape i think i would
pay that but probably not much more.
It's only in the 50cc class with points ign.

Geeze Louise,

if we don't get moving it will be into next year before we hit page 166, me thinks Uncle Lee could fill the page (and a little more) with his collection!

No love for the old SDs,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,


GOOD, I like it like that, leaves more for me, me, me.

I love mine, still got them, still use them but don`t need any more than the 9 I have now. They all run fine and are there to use when I need them. Funny ,the 115`s gets used the most.

 

[tbone75]

I would like to get to mine , just not happening for a while yet. Lost track of what I have ? Just know I have a few ! LOL

Little wonder! You chainsaw whoarder.....LOL

Indeed,

ole T-bone has been sitting on some 143 cylinders that no doubt have not seen the light of day fer years.

Dat's OK, I found a good one and the damned thing even has a nice full wrap. and a 120/116si to boot.

I am my Mothers son, not quite a hoarder, just never seem to get rid of anything.
