Setting the idle in a Corvair!
setting the idle in this engine, a 110 HP with a 270 Isky cam...normally, I
set the idle at around 6 to 700 RPM; when the chokes kick in, I set it to
around 1100 RPM. It might vary depending on the size of the cam you are
using, and personal preference. With this engine, I am running a dual Exhaust system, the RPM is a little
lower so I can hear the rumble. For more info, don' t forget to refer to
your shop manual, or give me a holler, I will be glad to help you out to
get your ride going.

Adjusting Corvair valves is a snap!
An easy way to adjust Chevy Corvair valves without making a big mess: split
a stock valve cover in half, that will catch the oil ( if you need a used
valve cover, check our website www.rafeecorvair.com under used parts, we
have them in stock, as well as many other gaskets to finish the job) ....If
you are doing a maintenance valve adjustment, install your oil catchers
on both sides, let the engine warm up, and starting at either end, loosen
the nut until the rocker arm starts clattering/ knocking/ ticking (LOL),
let it do its thing for several seconds, then re-tighten til the noise
quiets down, stop and then go 1/4 turn more. Some even go 1/2 turn to 3/4
turn. Myself, I do 1/4 turn to 1/2 turn and it works. If the engine is new,
you can do this 2 different ways: cold, as outlined in the shop manual, or
with the engine running, as I prefer. Make sure all the rocker arms are
tightened, but leave some small amount of play between the valve stems and
the rocker arm tips, so the lifters can pump up. I want to explain this
the easiest way that I can, not too technical, so everybody can follow. If
the engine is new, I normally let it run for 20 to 30 mn, I want this baby
to be hot, so the lifters can pump up ./ fill with oil. Then I start
tightening 1 rocker arm at a time, starting at either end. Just take the
clatter/ knocking away, and no more. When you are done doing all that to
the 12 rocker arms, now you are gonna adjust one at a time, by loosening
each one, let the clatter/ knocking come back for several seconds, and
tighten til it quiets down. Then go 1/4 turn more. Repeat the process til
all are done, and VOILA! I told you it was easy.....If you run into any
problems, don't hesitate to call Rafman at 918-753-2486. Happy to be at
Corvair Cold Start
Haven't made a video in a while, nothing really to make a video about I
guess. Anyway, I start my 1960 Corvair up in the cold.. It's been sitting a
while due to transmission issues.
