It's a 2 stroke so simple is the word :thumbsup: get it cheap and jump in , if the engine is locked up get it real cheap , a locked engine is a major thing and often the case on a 2 Stroke , looks like a 50 dollar -100 range , my guess is it's a points set up which would be simple, if cdi simpler if the parts all work , if you have a bad unit it's a throw away and replace type thing and parts might be a tad hard to find, still get it cheap and go for it
