Drop a few drops of gas into the plug hole and see if it fires....if so, its not getting fuel through the carb. Check the fuel and impulse line for cracking or other deterioration. I wouldn't suggest dusting it with ether because too much could blow a hole in the piston or score the piston and cylinder wall. Some guys do though just to see if its not getting fuel...

What's the plug look like when you're trying to start it? Is it wet with gas? Is it dry? Is it carboned up? The plug can tell you a lot.

SOURCE: stihl chainsaw 066 died

mr siegs
remove the muffler and look inside the cumbstion camber and look at the piston.if you see marks (score) on the piston the piston and cylinder are bad and need to be replaced.this is caused from a lack of lubercation to the cylinder,possible water in fuel,spraying starter fluid into the saw,bad oil to fuel mixture,old fuel has no lubercating value.any more questions please feel free to contact me

A business card placed between the flywheel and module works quite well (the magnetic attraction even holds it in place).and is easy. Rotate it by hand when done to ensure there is no contact. HTH

Make sure all the wires are hooked up to module.Then unplug ignition switch and test for spark.If you get spark then switch is bad.

Did you adjust the L screw on the carb to 3/4 open from closed and the H screw 1 1/4 turn open from the closed position. When you installed the new points, did you adjust the timing on them? Also, remove the chain and bar from the saw when you do this, you may find that the clutch could be damaged causing the chain to bind.

Air cap on ignition module Echo PB-413H blower

The air-gap between the ignition coil module and the magnets of the flywheel is a close tolerance. It is adjusted to about .010"-.012". This is approximately the same as the thickness of a standard size business card. I double the cover and let the magnets on the flywheel (lined up with the coil legs) pull it in tight 9compressing the paper card) and then tighten the adjustment screws. The screws have been known to vibrate loose and the gap would be lost. You can use threadlocker on the screws (optional) or just tighten them down well. Too large an air-gap is bad, but the closer the air-gap, the stronger the spark.

Blower doesnt step up to full power- have changed engine and carb.fuil line is clear with new filter and adjusted.Machine is 6yrs+-am thinking coil needs replacement or gap is wrong.Whats the air gap 010...

The spark plug should be about 0.025" gap. With a fresh plug, the spark should be blue. If fairly weak looking, remove the cover over the flywheel and reset the ignition coil gap. Turn the flywheel magnets to just under the module, insert a thin business card into the gaps, loosen the module screws and let the module contact the magnets through the card. Tighten the screws, then turn the flywheel somewhat to release the card. Turn the flywheel one complete turn to make sure the gaps don't close further. Recheck for hot spark. Check the air filter and muffler for plugging. Hope this helps!

Getting no spark on my stihl sh85 blower/vac

You will need to check the air gap at the ignition coil/flywheel. It should be about .010"-.012" where the magnets in the flywheel pass under the coil legs. That is about the thickness of a regular business card. So, some disassembly will be required. If the gap is closed, or too large, you would have no spark. If the gap is OK, then the coil may have failed. Make sure the screws holding it to the engine are tight, and if you remove them, you may wish to use threadlocker on them, so they don't vibrate loose and cause the gap to change. If you need more help adjusting the air-gap, please post back.

My fs55r wont start - got carb kit, new filter and sparkplur what next?

You need to make sure it is getting a nice strong spark. The electronic solid state ignition control module (coil) controls this and the contact legs on it have to be gapped about .010-.012" from the magnets on the flywheel. This goes on under the front engine cover. First, check for a nice blue spark. If it is weak or yellow, the coil needs adjustment. They fail rarely. A standard business card is about the proper thickness to produce the "air-gap" needed to create a a good spark.Also, make sure the plug has the correct gap on it.
If you have to check the coil, the front engine cover will have to be removed and moved forward to access it.Underneath the cover is the starter/recoil unit and under that is the flywheel and the coil. The coil will be attatched to the engine cylinder with a couple Torx screws about size T-15 or T-20.
