Ryobi bp42 backpack leaf blower won’t start, help please

[StarTech]

Remove the kill wire from the coil and try. IF still no spark then replace the coil.

As the BP42 there is at least three versions of this blower and the RY model number is needed for parts look-up. Either you have standard type cube or a rotary barrel version.

Just making sure, the kill wire is the black one that slips on and off easily right?

Well it is not the one that will bite you when it is working.

Little trick here is most battery drill do not spin fast enough to get a spark
So use a mains power drill on its highest speed and do it in the dark

Wow, really?! I need to do the last few things I tried all over again. All I have are cordless drills.

Most new engines idle at 2000+ rpm and run around 10,000 rpm
The magnetos are designed to provide the best strongest spark at full speed and just enough of a spark at cranking speeds to start.
Cranking is a lot faster than most people would believe
And no, without battery power you can not have our cake & eat it
either the spark will be good at full speed or good at idle can't do both without complicated electronics that in practice have all failed so been abandoned ,
I have pronounced brand new coils dead in the box only t find out latter they were just not getting enough RPM so now I use the bench drill set as close as possible to idle speeds

@bertsmobile1
@StarTech
So I’ve replaced the ignition coil and I have spark but it’s still not turning over

 

[bertsmobile1]

Turning over = revolve
Start= goes bang
Won't catch = fires but will t keep on running
Please be a little careful with your diction because the words s all we have to work with .
So now try a SMALL SHRT shot of starting fluid / carb cleaner ( is better ) / fuel down the plug hole with a warmed plug
It should go bang once or twice
If it does then do the same down the carb throat
Lett us know what happens

Ok, thanks, so it’s not starting. So a couple questions: where’s the carb throat ( I’m assuming that’s the hole the air passes through), and how do I warm the plug? Fuel is definitely getting to the plug if I haven’t mentioned that already.

put a half teaspoon of gasoline on the air filter or in the carb throat with the air filter off and see if it runs for a second.
