Thanks for the link to the Carb removal post (it's great") and advice. The reason I assume it is the carbs causing the throttle being stuck is the bike has been sitting un started for over a year. Before I bought it the owner was fine with having me pull the fuel tank and looking for a reason why the throttle wouldn't turn, seeing no obvious mechanical issue with the cables or linkage and the fact that the gas had that horrible varnish smell I guessed it was severely gummed up. It did crank over fine (had to bring my own battery) On a side note I found the ad for the bike on offer up and it was over a year old. When I asked the guy why just one ad on one site he said his wife wanted him to sell it and he hated to so he felt that met her requirement of trying to sell it. There were other ads for Ventures and about half of them stated "carbs cleaned / rebuilt" Also the trunk lid was cracked where the prop mounts I assume this is common due to the way it locks rigid on opening but if you forget and push it down excessive pressure is put on that section of the lid. I've already made an aluminum plate to distribute the load over a larger area.
