[Gasification] Fw: Woodgas and engine tar

[Ken Calvert]

Talking about tar;
One of my collection of gasifier stories was from a dutch fellow who as a 
boy assisted his father run a wood busines in the Netherlands during the 
second world war.  They had a truck fitted with a gasifier and his first job 
in the morning was to lift the cylinder head cover and  hit all the tappets 
with a soft face hammer  to free up the valves.
The truck was the fired up and it had to run continuously all day even 
through lunch breaks etc.  Because it it sat for more than 10 minutes it was 
very difficult to start again.   Cheers,  Ken C.
