I’m back at the KLR now that the spring nursery rush has slowed down. Despite most of your best advice i’ve decided to go wood instead of charcoal. I am very aware of the reasons not to -but i’m doing it anyways! So, that considered i’m studying T. Reed’s Handbook and working on design layouts. What i’m finding is that there are different methods of calculating gas consumption/ requirements and thus the sizes of pipes and components. and as a newbie i’m finding this overwhelming.
Its a 47 HP single cylinder (at 6500 rpm) .
Existing carburator inlet pipe is 2" . exhaust is 1.5"
From T. Reed.: Using the calculation for down-rated actual HP = (mph x (hp-h/gal))/MPG
HP= (50mph x 10 hp-h/gal) / 40 mpg = 12.5 HP
This would allow keeping the RPM below 4000 easily
T. Reed’s book says this level of power would call for around 1gallon of gasoline/hour or around 22lbs of wood. Thus the imbert throat diameter would be around 2" and the hearth capacity would be around 140 KBtu/hour
Any feedback on this from those in the know before i commit to it?
