Might just be a broken wire?

when I sent the last post, I suddenly thought, there could  be a break at the plug cap. I'll try to take this apart in the morning.

ok, checked the main HT wire there was a lot of corrosion where the connector attaches to the plug. cut that back 1/2" and now get continunity from the black and yellow wires.
meter reads 1.48 Megohms from both wires to plug cap.
voltage on HT cap .79v when cranking the engine. Still no spark though.
I would have thought there would be a lot more voltage tha 0.79v

Is there a definitive test for the HT coil??

best regards

The ultimate definitive test is spark!

When you are making these tests to see spark, have the spark plug out and pull the flywheel over as fast as you can.

The spark is often very thin and hard to see especially outside in the sunlight.

Ok guys.
The outcome....

Went to a Jonserad dealer in Spain who was very helpfull. we discussed the problem. but they couldn'y say on way or another which ignition module it would be. for bothe modules 125
I thendecided to chance my arm segundo mano por favor??  Any way 10 minutes later he came back with a big husky. Not sure of the model pulled the started to prove spark.  45 for both units. got home fitted ignition unit on right. the one I thought it would be. still no spark. Then fitted ignition module on the left. pulled starter.....
We have spark. re assembled starter unit and fired the old girl up. Purrs like a noisy kitten.....

Then a problem. Stupidly i didnt reinstall the chain cover and the clutch unscrewed itself and rolled across the floor :'(
Recovered the parts, reassembled inc chain cover. enging started to turn over  then no resistance when pulling.
Noticed the flywheel was slipping on the crank....

Strip down again. The sacrificial crank pin key on the crankshaft had sheared off.
Back to the shop New flywheel shear pin 1.50

reassembled again.

starts, Working again....

Although there may now be another problem..
There seems to be a lot of end play on the clutch 2-3mm and I dont think there is oil getting to the bar. I wonder if i've damaged the oil pumpdrive gear under the clutch.

What is the best way of locking the crank when doing up the clutch?

best regards

Most of the time if you have the saw completely assembled with the bar - chain - cover, the clutch will tighten itself.

If you want to keep the crank from turning, raise the piston above the exhaust port in the direction it will try to turn, stuff some starter cord inside the cylinder through the spark plug hole. This will hold the crank for your flywheel or clutch work.

 ;D There a few things that most us who are honest about it have done .Install a chain backwards ,put oil in the fuel tank and rocked out a chain .

A few  of us have spun off a clutch but on that very few of us have ever done so twice because that's one thing you never forget .

I spun one off in a driveway that must have rolled 150 feet and was lucky to have found it intact . I'll bet it's real thriller to blow one apart inside of a building and have it chase you around . :o

I remember the first time I put oil and fuel in the wrong holes was on an echo 280 great little one handled limbing saw not cheap either. Took it back to the dealer had a real good winge about a near new saw not running walked out feeling a complete dick head  (mind you I did say the first time and I admit it wasn't the last)

I have a little plastic Mac 3200 type chainsaw. It is OK for what it is - a yard pruning saw .  But the fuel tank is in the front and the gas tank is in the rear.

I've put bar oil in the gas tank 3 or four times over the years. I get so mad at that chainsaw for being backwards.
