I'm screwing the spark plug back in and i feel a bit of ressistance in this one spot. So i take it out, spray it with some fogging oil, then twist it with my fingers till it screws in freely. But I aimed a flashlight at the threads and the bottom 1 -1/2 winds of thread were broken off. (they either fell into the engine when i took the plug off or the engine gobbled em up!) The engine had 5-6 winds in total, so now it has 3 to 4 winds left holding the plug on. And this is on an engine with a poop load of compression! (mtd 31cc, but same engine as ryobi 31cc). Will the 3 to 4 remaining winds hold the plug on, or will it shoot off like a bullet?! I don't want to use a repair kit because the compression might leak!
Also, how can I make this thing more powerful? It already has tons but the more the merrier! I was thinking bending the reed valve retainer out so more fuel can get in the engine (but then i could get reed flutter at high rpms). So far I have sawed off a big rectangle at the bottom of the muffler, and removed the spark screen. I gave it my biggest carb, too.(about 11 to 12mm at the butterfly)
But I really love this thing! So far it goes around 60 kmh, but i'm getting a pocket bike clutch in the mail for it, and adding GEARS! (3 speed pedal crank cassette on rear wheel). The engine has tons of leftover power with the 1 speed. I'm going to make a post about it (It's chain drive with a primary reduction from an angle grinder).
