Horizontal Hit and Miss #1
This is the
first engine I have built ,quite an exercise as have only recently
acquired a lathe & mill. I am 71 years old so left it very late !!
I live at Waikuku Beach ,in the south island , NZ.
The engine is built from David Kerzel’s plans with very few changes ,
the proportions are very good, & is built from bar stock ,mainly mild
steel.
I only bought the timing gears & the spark plug ( 14/32 ) plus the
ignition parts. It weighs about 5 kg.
Bore is 22mm. Stroke 25mm. The cylinder sleeve is chrome moly , piston & con rod alloy, with Viton O ring. Flywheels 105mm. Mild steel.
Ignition is
J.E.H. module with hall sensor running on 4.8 volts , have included
retard & advance, but seems to start & run on about 8deg btdc.
Made the valves one piece , real tricky little things , but eventually
got compression. Am running on regular petrol plus 5% wd 40. Is
starting
First flick most times, running about 500 rpm.
The wood in the base is Black Maire, a native of
NZ.
YouTube - model engine ronald to see it running.
Note: Several people have started to build this engine and I believe this is the first one I have seen running. Ronald made a bunch of changes but that is what's so great about this hobby is adding your own ideas. David Kerzel
