Carbie troubles!

rubisubi · Post by **rubisubi** » Tue May 06, 2008 9:13 am

Hey guys, was getting the car ready yesterday for fishing and i had the ignition turned on ie all lights lit up but motor not running! Then i went to start the car and it wouldnt start?? Thought it was flooded so tried to roll start and noticed smoke coming out of the engine bay. Turns out it was some wires which melted???

In the back to the carbie (EA81 Hitachi) there is this small round cylinder type thing which was extremely hot and the wires melted. I need to go buy another one, does anyone know their correct name and what would cause this to happen, or did i leave the ign on to long and purely the current running thru cooked it?

Any advice would be great guys.

Fuel cut off solonoid. Leaving the ignition on didnt kill it it probably had some bare wire that earthed it you may find if you re wire it that it might still work.

Cheers SubiWan, i tried fixing it half way down my street, unfortunately there are no wires left to solder and the unit itself was badly burnt up. Will go to repco today to see if they have any! Not sure who would sell them unless i try a wrecker. Ta RubiSubi.

That solenoid in the back of the carb is the float bowl vent solenoid to the charcoal canister, not the idle fuel cutoff solenoid.

I had the same happen to mine, the windings goes short circuit and then it blows your ignition fuse, good solenoid reads about 20 ohms.

It would have failed on the road, so lucky you were at home.

Spot on Gary, its actually the float bowl vent solenoid (not that i knew), the guys at scorpion subaru were very helpful over the phone. They reckon they are more of a hassle than worth it, their recommendation (which i did) was to take it off, take out the barrel, block off the wires and put it back in. Spot on again gary, ign fuse was blown, put a new one in and it started first pop. The car was cold and now starts without having to even use the choke??? If it runs this well permanantly ill leave it as is. Some might say a blessing in disguise. Cheers for the help guys, hopefully this info may be of help to others in the future.

So you took the solenoid off, took the guts out, cut the wiring and put the now in-operable soleniod back in and it starts without the choke?

If this is what you've done, i'll be looking at the same thing on my L that's running a 1984 hitachi carb that is hard wired to get around the now useless ECU to run the engine. It has major trouble starting when its cold, more so in the morning than the afternoon...

Let us know how it goes, cos i'll probabily do it this weekend...

Cheers

Hey El Freddo, yeah just 2 bolts to take it off, 2 as part of the cable linkage and 2 for the unit itself, pull it off, slide the barrell and spring off, cut the wires and isolate properly and the put straight back in, very simple. So far so good, ive taken the car for several runs and runs fine. Actually its never started better, first pop and it fires up. Good luck.

Mum stole her laptop and took it interstate - how rude! Its the only computer at m&d's joint that can access the internet.

Anyway, today I pulled my carbie apart. Nothing seemed to be wrong with it. I blew compressed air through all holes I could find. No excess crap could be seen to blow out.

I made a new gasket out of a coles cornflakes cardboard (yes, it is good for breakfast with a little sugar as long as you plan eating by 11am) installed it during the-put-back-together-stage, fitted carbie, primed fuel and bang, off she went without much trouble. Interesting test will be a cold start.

On the way to benders she ran better than usual. Good throttle response but still a slight hesitation before the secondaries open up - not as much as it used to though which is good.

Tomorrow morning will be test number one. I didn't isolate the solenoids - ther were two of them and when the power isn't connected to them the engine won't idle - found this out when trying to get the thing going without any wiring to the engine as it is a "temporary" fix to an MPFI problem...

Fingers crossed it keeps me going til I get a "real job"...

Cheers
