A few Aussies swear by , rather than at , them . Dallas Hanna on here being one .
Ive finally figured a intake priming tube for the H.P. 40 R.P.R. will save a few hassles.
a alum. or copper pipe to intake from outboard, to use a syringe to give correct prime.
Then its either tip the nose down , or blow tube on vent, to see fuel line is primed.
For first flick starts.
Climate would affect intake type. I got 1/4 turn differance on the neddle from top cowl
off to fitted, just useing the nose intake, for the same flight r.p.m.s
Presumably if you fly in the snow youd use this ' carb heat ',
and if you frequent the Saharah Desert , a ' cold air ' intake might be usefull.
Would also be a way to choke injun , If a stiff tube from venturie went outboard,
Putting the tounge or some other extremety over this should result in depression at the spray bar.
and permit a more conventional approach to fireing the sucker up .
How much does the 51 weigh ?
