Hi Guys, Just bought my first bus, a 75 kombi camper. Pretty nice and having fun with it. In time I'd like to tune it myself so am in the process of getting the necessary books and info to start better understanding what I have and how it works, along with fix all the little problems as they come up. So, I've got the Bentley manual and Muir's How to Keep Your Volkswagen Alive in the mail - looking forward to receiving them! My question though, relates to my carby setup. Engine was rebuilt in 2009, how well I'm unsure though I'm told it was a Conti build (cash only no receipts). I've only just started looking, but it seems I have an 1800 (73-75 era) with dual weber 40IDF's and a dual exhaust. First question, is this is a good setup? Why? Secondly, and more importantly I've heard that weber's are hard to tune and as they are a modification from stock I'm not expecting to find much info in the two books I've purchase (though not yet received). What would you recommend as the best book to help better understand and tune these carbs, keeping in mind my specific setup. Also, while I'm fairly good with tools and such, I've never tuned an engine so it would need to provide all the necessary info and not just some random jet settings or something, any book would probably need to discuss how and why to help me better understand as I'm just getting started. Lastly, i've been trying to contact Conti Engines to confirm my engine was built by him but never get anyone pick up the phone. Does anyone know if Conti has recently shut up shop or why he wouldn't be answering calls? Cheers!
