Sh*t I broke a screw off flush in the motor front bracket stud holes

A tap and die set, make sure the material is stronger than what you are trying to add threads to. You can do it to all your mounting holes and just make sure you purchase the same bolt measurements as the tap you use. Or you can wait till this happens again with the remaining chinesium mounting bolts.

depends what kind of motor it is - normal 2-stroke is aluminum and there are pics here about how to make new holes on top to attach to frame with angle iron

if yours is cast iron, you need to send pics

There is no way that this 2 strike engine is aluminum. It weighs at least 9 lbs.

Got a magnet?
It's the same engine as everyone else has. I don't know if it is truly "aluminium" maybe another chinesium depleted uranium alloy lmao. It has a steel crank shaft and flywheels, and rod, and cogs, and hollow clutch spindle thingy I don't know the correct term.. loads of steel parts basically.

my engine is mostly aluminum w/ mostly steel fastening hardware. yours probably is too - I don't think you'd ever see aluminum Bolts & studs into cast iron/steel

metal is really heavy. think about a small pistol like a .22 target pistol or a .38 snub nose, they're pretty small but they still weigh like 5-7lbs. if your engine were all cast iron it would probably weigh 35lbs, dry

it is aluminum, search on the board here for pics of how to drill vertically thru the front mount to attach a piece of angle iron that can then be used with a u-bolt around the frame

often times, the case metal is too fatigued after stud removal to hold a helicoil well

those things are definitely aluminum. a cast iron engine that size would be about 30 pounds
