When heating the engine to start it for the first time, don't just place the heat gun at the top of the engine, you need to move it around the sides and even the bottom of the chases where the crank case and bearings are. You need to get a good amount of heat in the engine before trying to prime the engine with fuel this will make it start a lot easier. Make sure your glow ignitor is charged fully, most of the Nova plugs come with a little oil in them, I always take them out first and test them to get that bright glow before trying to start the engine. Replace glow plug, heat all around the engine, top, bottom and sides.....prime the engine, then it will start right up. If it does not fire off and stay running lean the idle screw a hair just enough that it fires and stay running. From there follow who ever you follow for break in. My method I have been running these engines for 20 plus years never has failed me and they last, but we all have our own way. Getting it started for the first time is pretty standard. CHARGE YOUR BATTERIES IN THE GLOW IGNITOR AND BOX FIRST!, HEAT ALL OF THE ENGINE, PRIME IT, THEN IT WILL START,
