Symptoms

This Shadow was not getting any fuel in lodge to fire upwardly, even with the choke on. The just manner it would run is by spraying some starting fluid inside the carb throat.

Diagnosis

Once the carburetors were apart, I found the pilot jets and choke tubes completely plugged up. The choke tubes supply fuel from fuel basin to enrichment/asphyxiate port for common cold starts, while the airplane pilot jets supply fuel at idle to ⅛ throttle positions. These are classic symptoms of letting fuel go stale and eventually leading to varnish build up.

The set

The simply style to clean the carburetors is to completely detach them and give them a thorough cleaning. There are no shortcuts (believe me I would love to know of whatsoever) or anything magical that you your into your tank to brand this whole process easier. In one case apart, you can dip the components in solvent, soda nail, and use carburetor cleaner in a aerosol can.

Carb removal & install tips

First off, I did not follow my own advice and read the service transmission prior to tackling this project. Apparently, information technology is easier to remove the carbs with the intake manifold (rubber carb holders) attached to the carbs. I eventually removed the RH side kicking, and the carbs slid right out. When installing the carbs, make sure to spray some silicone spray on mating parts to assist everything go together with less effort.

Purge and inspect the fuel organisation

The service transmission covers how to bypass the fuel pump relay in particular. Why would you lot want to practise this? Well, there volition exist stale fuel in your fuel filter, pump, and lines. Then empty out your tank, fill up with fresh fuel, and purge the lines. This volition guarantee fresh fuel into your freshly cleaned carbs, and should brand firing it up much easier. Make sure to inspect your tank for rust. If y'all find rust, see this postal service on how to make clean and seal it. Finally, make sure your fuel filter is clean, supersede if necessary.

Pilot jet & fuel screw setting

If I were to practice this carb rebuild all over again, I would have installed larger pilot jets, 1-2 steps up from stock. The fuel screw during tuning ended up three.5 turns out, which tells me the pilots are also small. Ideally, you want the fuel spiral out 3 turns max. Larger pilots would make throttle response much better. For more information on pilot jet sizing, see this postal service, and picket the video below.

Parts

Although the float needles were in "OK" condition, they started to testify some signs of wearable. There was a faint wear ring on the tip of the needle. Normally I reuse these parts, however given what a PITA information technology is to remove and install these carbs, I'm non going to take a chance having to go through it all again! The carb gaskets have seen better days, so I replaced them likewise. Beneath is a rebuild kit that is way cheaper than going OEM.
