I finally braved the cold and got my 13B swapped NA up and running again.Last time it ran it was with my old dellorto setup https://www.nopistons.com/forums/pub..._DIR#>/sad.png I miss that old reliable carb. https://www.nopistons.com/forums/pub...O_DIR#>/11.gif I got it to run with a few cranks of the key but I still need to set the timing with this carb setup on it.My problem I am running into is the car want to rev to 6k and stay there when its cold.Is there something I can adjust on the carb to set this lower is it something to do with the throttle cable?I did have to build custom linkages because the factory weber linkages like to snap and bend like twigs.At least it fires up now.Never tried it since this carb was working right.Any help is usefull.Heres a quick pic of my beasts engine bay for those who even remotely care.





Thanks.

I wish I knew more about weber carbs.

is that what it looks like when you take out the rats nest?

Sort of. Your engine will have 12A in raised letters.

Ahhh, running a sidedraft webber. 48 or 51mil

its a 45 DCOE.And doesn't like to idle with the pump fuse on it.It floods out really easy.Any ideas why???

Fuel Pressure too high, and/or dirty carb.



Try lots of carb cleaner first.

Clean it to get the carb to work properly.And its on a stocker 83 pump.As soon as I get it to run without the fuel pump fuse in it runs on the gas in the system then when I put the fuse in it floods out.Thank god for new spark plugs.Fires back up after a little cranking.

would running without a fuel filter in the carb make it run richer???

try leaning out the idle mixture

I need a new fuel filter for the carb anyways so I will order one tommorow.Anyone know what pressure a weber 45 needs to run it right?I am using my stock 83 pump and as soon as I put the fuel pump fuse in not even 12 seconds later it'll flood.This is nuts. https://www.nopistons.com/forums/pub...1047683358.gif

I have read that it is about 4.5 PSI or at least thats what I read somewhere.



But it would be best to run a variable pressure regulator that increases pressure while the engine is under load. This will remedy the fuel starvation problem inherent with this type of carb.

have you checked the needle&seat.my weber will ocasionally flood.with a ctock fuel pump,you shouldn't have any fuel issues intil you are under load .the stock fuel pumps where barely adequate for stock carbs.but i'll bet your needle&seat are sticking.let me know ifthat's the cure.
