Im not a "pro", but sounds like a timing issue!?

Welcome to the site. Wow one post and supporting member. Good for you.
Sure your valves are adjusted right? Or carb?

Sounds Like Carb or Governor Linkage Issues.

Timing is the only thing that should cause an engine to shoot fire. But the OP posted that it idles...... and idles high........... I think more of an actual description is needed.

The governor spring can be adjusted just takes a trial and error way to get it where you want. You can stretch, shorten it etc.

As for the timing -remove the crankcase cover and make sure the cam and crankshaft line up. They should each be marked you just have to line them up together.

I dont know how bad your case of engine shooting flames is but its usually common to have a spark or flame shoot out the exhaust when your revving it to high RPMS with no load.

Post some pictures for better help.
