BR 380 NO START

My BR 380 purchased in 2011 won't start. First the cylinder was flooded to the point the rope could not pull past TDC. I dried the cylinder and it flooded again. Rebuilt the carb with a Stihl rebuild kit, no flooding but no start. New Stihl carb, no flooding but no start. There is a spark, but it looks weak. A little starting fluid in the carb, no start. Took the spark plug (new) out sprayed starting fluid into the cylinder. No start. Fresh gas with alcohol free fuel and Stihl premium oil.

I'm thinking the only thing left could be the coil.

What do you think?

Thanks

Two things.

First if the cylinder was flood is possible the crankcase has a lot fuel mix it too. So it take a lot pulls get it cleared.

Second have you bother to check the spark arrester screen for clogging? Clogged spark arrest = engine that can't breathe.

One thing I left off my missive was the muffler. I also removed the muffler to inspect the piston. While off I tried starting with no luck. Yes, thanks, the spark arrester is clean.

Also check the compression. It must be above 100 psi for the engine to be able to ignite the fuel/oil/air load.

I honestly don't know why it is, I guess the best thing would always be to call a technician who knows about this type of things, maybe you need a repair right now.

Not the coil. A new coil didn't make any change. A good spark and starting fluid didn't help. The blower belongs to a club. A club member took it to "his shop". Owner said it should be a 5 min fix. It's been 2 weeks now.........

It likely has the sheared the flywheel key segment. The flywheel magnet could also be rusty and creating the weak spark
