Hard Cold Start

[RB30-POWER]

rb25 air reg is good, unscrews into half and you can see internals and clean easily, earlier rb engines it is solid alloy and can't see shit because it is pressed together, however, cleaning it through the hose holes still fixes them 99% of the time on the early type.

when you seperate it, just be careful on the gasket, it will tear in two usually, but just use some silicon to seal it back up, but go easy with it, you will not need much at all for a successful seal.

i usually use wd40 to lube and clean them, you usually don't need to use carby cleaner as they are never that bad, it is just the mech inside get a little stuck and the wd40 lubes and cleans at the same time, move the mech at the same time a little to free it up if it is stuck.

That is a really awesome tutorial, the cold air reg looks like a real pain in the ass to get too. The fuse I replaced was the Engine Control fuse, I think it's a 20A, this fuse was causing issues with any aftermarket ecu that I tried to connect up, they simply would not power up but the funny thing is that the standard ecu would still work but was prob operating in limp mode.

Seems like it's even harder to get at than in the RB20...
