Not a condemnation of Carburetors – if set
up and adjust correctly, they work just fine. However, I recently had a friend
survive an engine out crash – due to rotary engine stoppage. He was not using a
true carburetor but an Ellison Throttle body. He had problems getting the
device to deliver the desired fuel – it appears that the model he was using did
not have sufficient dynamic range – in that when idle was adjusted good, it was
too lean on the top end, when adjust for good fuel delivery on the top end,
idle was too rich. Whether truly a limitation of the model he was using or his
limited understanding is uncertain.
My point is do not choose either a Carb or
fuel injection because you think one is inherently more reliable than the
other. Like everything else - either can and do fail probably more a result of
the user not fully understanding his choice rather than any inherent limitation
of the method of fuel deliver chosen.
It comes down to what you feel
comfortable with and are willing to learn (if you do not already know) and
understand the approach you are using. Failure to truly understand which ever approach
you choose – can result in truly undesirable side effects.

The only cars I see broken down on the
side of the road nowadays seems to be the ones out of gas. When was the last
time one of your modern cars let you down?

It frightens me as well Kevin.
I will admit
to being quite naive, but my decision to use the hard-to-adjust Weber carb
doesn't seem so impossible when I see so many postings like this. perhaps
phase II I will have fuel injection. besides, I have Lynn to help me! ☺
