Awesome find for $30 I'm impressed.You seem to have found the first version of the twin and from what I can see hasn't been updated at all.So it most likely has never been serviced.So your got nearly 40 years of running to deal with.So you need to check everything to make sure it is working.However due to it's age and the fact it hasn't seen any service (me personally)straight for the jugular.I'd crack the crankcase and have a look inside first.You won't hear me say that very often but considering what it is and the lack of servicing that's what I'd do first.There were many problems with the first version it could well have cracked rings.See how you go but that's what I'd do on this occasion.
as has the dodgy plastic carby
What's this?Dodgy carby what?.Why do people call them dodgy just cause there plastic?Once you get your head around them there not that bad or hard to deal with.
