350BT blower

[StrangleHold]

I've got a 350BT . Had it about 13 years. Been a really good blower. Since I've it I haven't even had to use the primer build to start except the first time. When cold I just put the whole on and it would start on the 3 pull Everytime. When warm it would start on the first pull, not choke.
Well about 3 weeks ago after I start it and use it for awhile, warm. Shut it down and now if it's warm it will not start unless I pull it like 40 times. Let it set till the next day it will start as always. I fix.my own equipment but wanted some insight if what the problem might be before I tore into it.
Like I said it will start when cold and run just fine but just can't get it to start when warm/hot.
Thanks

I've used a couple of these. I'm gonna guess the ignition coil could be going bad. My neighbor's 350bt had a bad ignition coil when he got it used. I had this same issue with my grandmas earthquake MC43 tiller and it was the ignition coil.

I thought of that. I kinda doubt it's the carb since it runs so good when it starts. I've been using my 150BT since this happened. I looked at the parts list and they list 2 different coils. I think the one on mine has been discontinued. Seems difficult to figure out what the replacement one is. Seems the compression is fine. Cleaned the filter and replaced the spark plug.
