Where can I find an Ignition coil for a Solo Model # 445 Backpack blower?

Question edited for a lot more clarity. It is a 'Stihl', not a 'still'. Please always state FULL 'make model (what it is)'.
Question moved to model category.

The standard way to test any HT Ignition coil is as follows.
Remove the spark plug and ground it to the cylinder head.
Disconnect the positive lead.
Ground a 12 volt battery - (minus) to the cylinder head.
Touch a positive wire to the positive on the coil and release.
The plug should spark when you REMOVE the positive power.

Only from the manufacturer.

there are several other issues that can relate to a 2 cycle not starting.
crankshaft seals
plugged exhaust
burned up piston/jug assy
you need to investigate a little further before you think you need to adjust something...

ignition coil fixed my still backpack last fall

There are 2 ignition modules that fit that model.
4203 400 1301 and 4203 400 1301.
Also check the ignition switch, remove earth cable from ignition module to double check that it isn't a dodgy earth lead. Ignition modules cost around 50 pounds + vat

I had the same problem.. First I was only getting 89 psi so I took it apart just to find out that the piston ring was half way stuck in the piston groove making it loose compression put it back together and it started. But it was starting sometimes and I almost gave up on it till I noticed that the cruise throttle needed to be at least half way up to start and now it starts all the time just have to make sure is half way up before starting... If you try starting it with the throttle down it will give you a little bit of a hard time starting it when you put it half way up.. You have to start it half way up right off the back

needs a new ignition coil..it's electronic and is affected by heat...the new one's don't have that problem...

I'll be waiting for the "how to change my ignition coil" post...and i'll help ya there too...

Hi

You can use any superior quality oil for 2 stroke engines.
