I need an engine rebuild kit for a SX66 Baumr ag chainsaw is there such a kit? Corrie


if you can't find one , be aware that the piston and ring will be generic fit for that cc engine so go to a mower shop with the bits and see if you can get alternate parts
for example I have homelite piston and ring in a husqvarna trimmer for the last 5 years and still starts and runs ok
as long as the bore size is the same and the wrist pin fits in the piston

Set up timeing on a 1951 norton es2


Norton has a heart shaped timing cover. Inside are two camshaft gears, and one crankshaft gear.

The crankshaft gear has two marks on it. The camshaft gears have one mark each. Line the marks of the camshafts, up with the corresponding marks on the crankshaft, to set the camshafts in time with the crankshaft.

Magneto Ignition:
Bring the front cylinder piston up to TDC, (Top Dead Center), after the Intake valve closes.

The magneto is dropped in, (Set in), with the rotor just before the No.1 pin, in the magneto cap. (Front cylinder is No.1)

If memory serves the magneto gear is a Helical gear.

This means when you go to set the magneto in place, you have to be back a few teeth on the gear of the magneto, so that when installed the rotor will turn to a position, just before the No.1 cylinder magneto cap pin.

Also remember to ******, (Turn the magneto back), the ignition BEFORE you kick the bike over.

After the bike starts turn the magneto back to the best idling position.
(Also check on the open road for the best setting, and split the difference.
Good for idling, and open throttle)

If this is Not what you asked for please post in a Comment.

Have got a joe hunt magneto and i want to put it into my triumph 750 1970 model is there a diagram for this or is there instructions on how to install it


I ran one of those on several 60s-70s Triumphs.....great ignition!

Both plugs fire at the same time so there is no left/right to worry about.

Remove spark plugs and gap .018. Remove timing cover (right hand side of engine) over battery ignition points.
Disconnect and tape (insulate) all battery connected wires. Better yet, unhook battery hot wire from battery terminal.
Hold breaker cam in opposite direction of rotation (advanced position) and rotate engine until the points on #1 cylinder just start to open. Note: Use .0015 feeler gauge.
Remove breaker plate, breaker cam advance mechanism, and dowel pin from internal taper if your model used a dowel pin to position breaker cam and advance mechanism. CAUTION Do Not Rotate Engine. If engine is rotated, reverse rotation until piston is down and the cylinder at least one inch before top center on the compression stroke.
Rotate engine in normal direction of rotation until piston is 5/16 from top center on compression stroke. Install magnetos adaptor plate and adaptor shaft in cam taper. DO NOT TIGHTEN SHAFT. CAUTION 1963 to 1970 Triumph unit construction twins have a different length taper on shaft and internal threads are dissimilar. Suggest checking threads and taper. 1963 to 1970 bolt has BSF 1/4 x 26 threads. 1971 and later bolt had 1/4 x 28 thread. Early shafts are marked with the letter "A". Later shafts are marked with "B".
NOTE: Some applications will require drilling and tapping engine with 1/4 x 20 for better security of magneto mounting adapter. Some customers with severe service report that they heli aced adaptor to cam cover with approximately one inch length bead, top and bottom for security.
Remove Magneto cover. With shaft slightly loose in taper mount Magneto so that points are just starting to open and bolts are approximately in center of slot (for timing adjustment later).
Carefully remove Magneto and tighten center bolt in shaft. Re-install Magneto and time. Install cover and plug wires. Hook up ground wire to a separate kill switch to ground only. DO NOT HOOK ANY BATTERY CURRENT TO MAGNETO.

HI, I have a Suzuki LT80, it starts ok but it smokes like hell and there dosnt seem to be much compression what could this be? thanks.


It seems you have worn rings and/or barrel and piston. You will have to get the barrel off the engine to ispect. Unbolt the carb and exhaust from the engine. Unbolt the 4 nuts on top of the head. Remove the head and barrel from the engine. Inspect the piston for scoring and wear. Remove the piston by removing the circlip next to the gudgeon pin. Do not drop the clip into the engine.(stuff some clean rags in the engine under the piston. The gudgeon pin can now be pushed out of the piston and the piston removed.Have the barrel and piston measured for wear.
If you're on a tight budget you can replace rings only but this is a penny wise pound foolish solution. You'll have the same problem in 2 months time.
It is best to rebore the barrel and fit an oversize piston and new rings. The barrel can also be resleeved but this is a more costly option and should only be exersized if you cannot obtain an oversize piston.

How do i go about replacing the piston and rings for my 2003 honda cr 125 r


Take off seat, and tank.
Drain coolant, remove exhaust, remove coil, and ground wire from head.
Remove triangle head stays, and spark plug.
Remove right side power valve cover, and clip and spacer for the power valve arm.
Remove four cylinder nuts.
(If you remove the lower radiator hose that goes between the left and right radiator, you can get the cylinder off without removing the head.)
Use a soft blow, or dead blow hammer to free up the cylinder (Piece of wood)
Use kick starter to get piston low, and carefully remove cylinder upward.
Put a rag around connecting rod, and remove piston pin clip on one side. (So the clip doesn't fall into engine) Then push the pin out and remove the piston.
Note, you will have a mark on the left side of the cylinder of "A" or "B" for a stock piston, but Wiseco's don't use this.
Use caution when putting on the new ring, and getting the cylinder onto it as not to twist the cylinder because it will "catch" the end of the ring and do damage.

Piston rings


First, be sure they actually do fit the bore. Take a ring and insert it in the bore. push the ring halfway into the bore using the piston. There should be about a 1/32" gap in the ring. Anything more than 1/16" and you need rings the next size up. If the ring won't go into the cylinder because the gap fully closes, the rings need to be a smaller size.

With the correct size rings, put them on the piston. Some pistons have an index pin in the ring groove Fit the gap to the pin. Put the piston mid-stroke and place the cylinder over the top of the piston. Squeeze the rings closed as you gently tap the cylinder downward and over the rings.

Please rate this solution. Thanks garethholleb!
