Question about Craftsman Garden

Craftsman 200 mph model 358.794741 Leaf Blower\r\nWill not fire. Replaced ignition module, replaced spark plug, set gap at .006, removed air cleaner, tried start fluid, cranked with plug at case - might be a faint spark, but inconclusive. The blower will not even attempt to start. I've run out of possibilities.

You need to check if the piston was fired, or if the piston rings was stick.

I have a broken spark plug wire. Can these be replaced?


Steve:

Yes, the spark plug wire can be replaced, but you have to buy the ignition coil as the spark plug wire is hard wired into the ignition coil.

If the metal spark plug connector has disconnected from the spark plug wire, the connector can be replaced, but if the spark plug wire has been cut you'll need to replace the ignition coil.

Got a craftsman leaf blower cranks up and runs fine for about 5 mins then starts losing rpms


ITs hard to diagnose these things over the internet, it could be so many things.
Is this a gradual loss of power? If so; Im sorry to say; that it sounds like its losing compression as it warms up. It is not cost effective to repair the unit.

If the loss of power is more sudden it could be a failing ignition module. Ive even seen spark plugs that quit working when they get hot.

To test this you will need a proper spark tester, laying the spark plug against the head will not provide an accurate assesment, and a can of carb cleaner. Run the unit with the air box cover and filter removed till it fails and immediately give a shot of carb cleaner in the carb and restart. If it starts right up it could be fuel related. IF it doesnt start right up then quickly test for spark. If no spark then its likely the ignition module. If it wont run on the extra fuel and it has spark then it has probably lost compression.

My chainsaw wont start! I replaced the spark plug and added fresh gas .It acts like it wants to start but doesnt I even sprayed the carb out with carb cleaner any ideas?


Check the fuel filter, air cleaner, and muffler for plugging. Check the condition of all fuel lines. Does the primer bulb fill with fuel when pumped several times? Check the spark at the plug (gapped at 0.020") which should be blue and snappy. If weak looking, you may need to reset the ignition module gap to the flywheel magnets with a thin business card for a gauge. Remove the left side case to expose the flywheel and ignition module. Turn the flywheel to bring the magnets under the ignition module, insert the card into the pole gaps, loosen the module screws to allow the module to contact the magnets, then re-tighten the screws. Turn the flywheel one full turn and watch the gaps to make sure the flywheel doesn't contact the module. Recheck for spark. Hope this helps!

Craftsman leaf blower wont start


The air gap for the ignition coil core to flywheel is adjustable on some engines and the gap does vary.
On a Stihl, I used a matchbook cover first, then doubled it and got the engine to start. That amounts to 8-10/1000ths (0.008-0.010") as measured with a digital caliper after-the-fact.
I'm troubleshooting another engine currently from a McCulloch Airstream IV that only has ~12 hours and no spark but the coil measures roughly as it should; around 1K Ohms. Was surprised to find the company went bankrupt in '99. Another one killed by Asians and fairly poor design.

No fire


If you have replace the spark plug and still no fire. It is the ignition module, that fires the spark plug, needs replacing. You will need a part # 3443d Tecumseh Ignition module.
Good Day.

I have a Poulan BVM200VS gas blower. The plug won't fire. It has a new spark plug and a new ignition module. The kill switch is good. What little wiring there is seems to be good. If you spin the flywheel...


It is possible that the gap between the module and the flywheel is not correct. This gap is usually set with some thin card stock or possibly a playing card.

It is important that this gap is not too large.
