Two things: Other than stock I think the CB2280 would also be a great choice of camshaft.It consistently gets rave reviews from people who use it on a mild set-up. Second: I think if you normally shift between 2-3k then you may be running the engine at too low RPMS. It's air-cooled. It needs...

Very interesting. Just had a quick look at the thread you linked to where you go into more detail. I find it interesting that at first glance it appears that the map is very close to the ballpark figures I mentioned in my above post. I'm quite convinced these get one pretty close to optimum in...

Do you have the 123 Tune (USB or Bluetooth) version? Cam and Carb do make a difference but more so for the vacuum advance function than for the "mechanical" advance. You can typically set ignition to 8 to 10 degrees before dead center at idle, 20 degree at 2000 RMP and about 30 degrees at...

I don't know what distributor that is. There is a Bosch unit ending on 050 but that's not what you have. Those are mechanical advance only, but yours seems to be what's called a SVDA (single vacuum, dual advance). I do think I can see a Bosch symbol on the distributor but the ones I'm familiar...

Can't tel what distributor you have from that picture. I don't think it's the correct one, as that should have a larger vacuum can. Is it a Bosch? If so it should have a Bosch number and possibly a VW number on the side, not on the vacuum canister. Does it also have a centrifugal (mechanical)...

The first sentence is correct. The second one possibly misleading. The "B" engine (1600 single port) has a "vacuum advance only" distributor. There is no mechanical/centrifugal advance. Follow the manual when setting timing. If the distributor is no longer the stock distributor then the numbers...

About 23/24 mpg on trips around Europe cruising between 60 and 75 mph with a 1776 single 34PICT 3 with 28mm venturi and jetted accordingly. That's including some climbs across the alps. I have the stock transmission so quite high RPMs (and lot's of noise). Longer gearing would get the numbers...

Thanks Abel. Opening the filter is standard in internal combustion aviation engines and does make a lot of sense.

I think you have got one too many zeros in there. 0.2mm is 7.8thou. Stock is 0.15mm or is just under 6 thou. Stefan

Hi Abel, I was just wondering: Would you modify the advise above when a full flow filter is installed? Cheers, Stefan

Hi Ozziedog. You are most welcome. And I think you are absolutely right about the much reduced friction in this steering set up. Stefan

Further update. The front end has continued to break in and the slightly less pronounced self-return to center is now almost a non-issue. A few people who know a thing or two about cars including, old busses, have now driven my bus with the rack and pinion conversion. 1. The guy who designed...

Not a definite answer as I'm not an engine builder but a couple of things come to mind: Compression ratio will be an important consideration together with cam choice. Cam timing and static CR will result in your dynamic CR which is what's important. So don't go too high on the CR wth a mild cam...

It's not really a direct answer to your question but I would first make sure that everything else is in order. Most importantly brakes, steering, lights, ball joints tires, engine etc. Then you can turn to optional things such as lowering. Probably the best way to go for lowering is a...

I don't know. He didn't build it. He is a very busy man as he also has an unrelated day job. He wrote the parts and specs list, made the heads and end castings and provided advise along he way. Everything else was done by a local builder.
