I'd certainly be interested in that...

Subject: [DOG mailing list] H36 spung tailwheel
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?
cheers

Interesting about tail wheel mod from Michael - sure gives smoother ride.
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.

Hi John and Lasse
I have owned a Mk1 H36 since 1988 (G-MRG in the UK, now VH-VRG in
Australia). It originally came with an un-sprung
