[SEL] Barn Fresh Fairbanks/ Now IHC Hot Tube Ignition

[John Hammink]

Wendel says that it's unlikely that hot tube ignition was used after 1905, 
since the well know valve gear was patented that year.
This system included a low tension make-and-break ignitor.
The parts book mention the ignitors for the 8-10-12 and 15 hp
engines from 1904 and for the 20 hp from 1906, through 1908 then
they changed them for another part number by 1909.
Funny thing is in all the 310 pages of the parts book, they didn't
speak about any hot tube.
