HI Andrew, I replied to this yesterday but it looks like it did not make it. This is only my own opinion, so the final decision is entirely up to you. I would rebuild the Twin you have now as they are now scarce in good restored condition. Bruce (Victa Man) has a new catcher for a Twin at his mower shop and you can contact him by emailing spare parts on this site. I would chase up another motor to play around with for the go-kart as this is for fun. If you scroll back to February of this year on this page you will see 15 replies to the subject relating to the Twin, I have commmented with some imfo on the last post (15) about the Twin, if you require anything else leave your email on this post . Cheers Brett.
