There is work to be done

As you can see some work has already been done

As can be seen from these pictures most of the work around the engine has been done but needs to be completed. As with all well laid plans of men and mice, if its not childbirth then its an Airshow, that took four weeks out of my plans. I just through in the child birth for fun. (AT THIS STAGE IN MY LIFE, YOU MUST BE JOKING) On top of all this I am also busy doing a conversion on the KR-2

The carb heat collector is one thing that I consider to be of utmost importance. This model is similar to the one on my KR-2 and that one works like a charm. The exhaust pipes are 38mm mild steel exhaust pipe and the collector is made of 50mm stainless steel exhaust tubing. Inside the cowling is a mixer unit that allows me to select either hot or cold air or any intermediate setting. A 50mm flexible airduct takes the hot air from the collector through the cowling to the mixing unit inside the cowl.. From there it goes via 50 mm flexible tube through the number 2 baffle to the carb intake.

As can be seen from the picture of the starboard inlet manifold there is enough space between the manifold and the oil cooler to allow for an exhaust ducting that   routes the oil cooler exhaust air through 90 degrees up through the cowling to allow for a good flow of air through the oil cooler and enough space to put in a control butterfly. The baffles for the cylinderheads are made of 0.5mm mild steel and is shaped around the lower halve of the cylinders to ensure airflow to the front and rear of the jugs the center airflow through the heads are spread by the "forget-me-not" between the jugs.

Carb heat mixer unit made of 50 mm aluminum pipe (Irrigation),
The one on the KR-2 looks and works exactly the same. The carb on this 1835 is a standard VW carb and is very prone to icing due to the normal butterfly set-up
