Re: [ihc] Carb/jets/choke



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.

I just did this conversion and as far as I can tell there is no way to keep
the electrostatic system with the 2300. There are electric conversion kits
available for about $25 but I don't care for electric chokes personally. The
benefits of a manual choke far outweigh the heavy labor involved with
pulling and pushing the cable. Jet size can be roughly calculated by where
you live and what engine you're putting it on. Perfect jetting is pretty
much unrealistic at home but you can get it pretty close through trial and
error. Listen to your motor. Smell and watch the exhaust. Check your plugs,
etc....The next best bet for proper jetting can be done for a little money
with a gas analyzer and most any auto shop will have one of these. Perfect
jetting can really only be accomplished through dynamic monitoring of the
drivetrain and analyzing of it's exhaust at the same time but that requires
a dyno and very few people will ever have their car on a dyno for normal
daily driving. Anyway you will be happy with the 2300 and it's simplicity in
both build and functionality.
Good Luck,

 Hi all .. Question

 My old carb either a 2210 or 2245 has bit the bullet....  By scanning the
 archives people have suggested going with a 2300.

 Questions:
 (a) How do i intergrate the 2300 with the autochoke system I currently
have ?
 (b) How do you determine the jet size needed ?
