Just found a quad bike in a parking lot, when I went to “borrow” it from its zombified owners I was made aware that it had no engine.
I got off, and checked it out. It seemed to have all the parts installed just fine? Not sure what was going on.
Engine’s broken. Things can spawn with broken and damaged parts now.
That would explain it.
I’ll come back with a welder under cover of darkness and give it a go.
