Re: [ihc] Carb/jets/choke

[Dave Nuenke <dnuenke@xxxxxxxxxxxxxxxx>]

I'll second in saying that there is sure nothing wrong with a manual 
choke, I have several of them. An electric choke can be handy though, 
really a matter or personal preference. When it comes to tuning and 
jetting a Holly, only time and patience will get it right on. I've 
tuned in a new 2300 and a new 4500, both on binder motors. You 
generally have to play with the jetting a bit, and deffinitly the 
accelerator pump, most IH motors need a fairly large pump shot. The 
only real way to set the carb for your engine though is to drive it, 
and continue to adjust it. As far as meters, I don't have any, nor 
have I ever used one. I do read plugs, etc, but I can usually tell 
what the carb needs by listening to and watching how the motor 
responds to different situations. For a first set up jets, use what 
it comes with if you're fairly close to sea level, drop 1 size for 
every 2,000 feet in elevation. This will give you something to start 
with, a 2300 comes with #60's IIRC. On my 345 at about 3500 ft I run 
#58's, but again, ymmv.
