Re: Johnson HD-20 Won’t start

[jsonova99]

When it’s running, I notice that’s it’s a bit unstable, initially races up to high rpm with throttle seat in start position, then calms down a bit. If I accelerate it responds ok, but going the other way it wants to die out unless I start playing with high speed adjustment. Again, this is with no load on it. Runs with a lot of smoke, expected to an extent with the 16:1, but seems worse than some of the ones I watched on YouTube, since that’s the only comparison I have. Defitinetly doesn’t want to run at low rpm. My fear is that this is a power head issue, but I’m still not 100% convinced of that.
