I'm keen on the idea of getting a sprung tailwheel on our H36 - the rigid one is not at all good on rough surfaces. I think the sprung wheels may also reduce the "bunny hopping" on rough runways....can anyone enlighten me as to whether this is the case or not? Last time I saw a sprung one I didn't think it would be particularly difficult or costly to manufacture - perhaps we could get some plans drafted from one of the dimonas with a sprung wheel and see about getting a few made up with appropriate approvals. How many of you would be interested?

You mention the heads/valves lasting only 300hrs. I would recommend to all analysis of exhaust at FULL POWER with lamdameter etc. You may find it is running slightly lean on full power (actually plugs look OK) but gas analysis does not lie. More recently i have been using digital CHT and you can really see what is happening. I set them up so full power CHT rises to about 170degC then very slowly falls. If you bring throttle back just a bit in revs CHT will quickly rise to 180degC and beyond. This proves to me you are running rich on full power- also confirmed on EGT. To achieve this it may be necessary to carefully thin out the end 6mm to 8mm of each the needle in carby and thus achieve the low CHT on full power. (do not think of touching jet) Fuel is cheap when compared to repairing heads. Limbach Tech bull 53 makes mention of max on climb of 180degC (forget what max the manual says - that is stupid value) Also Tech bull 44 (11page edition) is well worth a read.
