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!
