Hi All, I've been lurking around on here for a few years soaking up information while I got our bus ready for the road so I thought it about time I gave something back and hopefully it can help somebody out. I brought Sunny about 2 years ago from a fellow KC Member, he was a good solid bus but was in need of some rust repairs and some serious TLC. He's a 74 Bay 1800 auto, he was in far from roadworthy condition but we (finally) in the last 2 weeks got him registered and out on his first adventure with our family on the Australia Day weekend! I've been a watercooled VW fan for many years, owing a raft of Golf GTI's so when it came time for a mobile holiday machine there was only one choice of course and it had to challenge me so a 'proper' VW it was! Anyway I digress slightly and after our first road trip I was slightly concerned about his performance or total lack of, and after reading many posts about travel and top speeds, decided that something simple must be causing his issue. I knew he was mechanically A1 with pretty much everything you can bolt onto the engine being replaced or refurbished. So I went looking. I'd just like to add that I'm a diesel mechanic by trade so petrol fuel and ignitions can be challenging at times, but the posts and advice by many members on here and I would like to say especially from 1500king have been a first class resource. His dual carb set up procedure was so simple and straight forward and provided me with the perfect set up first time. So thanks to you all. It really is a wonderful forum. Anyway I'm waffling off topic again... So after deciding that a simple issue was causing my problem I decided to check full throttle first. So I got Mrs W behind the wheel and got her to hold the old boy flat to the floor That pretty much summed it up. Half throttle with the foot flat to the floor!
