Thanks for your insight guys. If a DIY rebuild will cost me roughly about the same as sending it out I’d rather send it out and know that it was done correctly. Especially since I don’t have any kart experience at all.
By car experience I mean basic maintenance and part swapping. I’ve never rebuilt an engine. Seems like this kart engine would be a great place to start but I’d rather drive the kart than tinker with the engine all summer.
I’ll call around and see if Comet can do it and how I should ship the motor to them.
