Hey, so a couple of us are ***** deep in our own projects but had to save an SA from the scrappers. It was totally original and cherished but got vandalized, and then mistakenly taken to a salvage yard where it had a car put on top of it. Anyways, she's been sat a while and the fuel system is as you'd expect so with that cleaned up we went for the fire up.

She took some coaxing but finally fired albeit only on one rotor - so we stripped the top half of the IDA and found a lot of crap in the float bowl...



Cleaned this all up, set float level but still no joy. Here she is in one rotor glory lol. Now look carefully at the venturi for the rear rotor - dry as a bone compared to the front one that's happy so this must be our problem right? Manually pore fuel down the venturi and you get life out of the rotor.



Now I'm new to carbs - spend my time faffing with EFI normally so this is a black art, so if I completely strip this carb is it likely to be something as simple as a blockage or could there be something more sinister going on?

 

Likely as simple as blockage indeed! A screwdriver, a can of choke cleaner, and an hour will do wonders I'm sure.

 

Sounds like a blockage to me.

 

yeah take ALL the jets and stuff out and clean everything, the passages too really well. you can probably do it with the carb on the car, but if you're comfortable taking it off and doing it on the bench that's good too

it might be a good idea to write down all the jet numbers.

if that doesn't fix it, it can be the fit between the booster and the carb body, any leaks there will have that same symptom. i've got a piece of paper as a shim in mine to tighten it up, the fancy places i think will use a set screw

if that doesn't fix it i'd look for vacuum leaks on the intake/brake booster

 

Ok cool I'll strip it down and post up jet specs too while I'm at it, she's running a streetport and did make 185bhp at the fly when she was built so must've been pretty nippy.
