The black solid floats cannot be tested in hot water, they should weigh between 10.4 and 11.5 grams, anything more and they are bad. Really bad ones weigh about 15-17 grams. _________________ http://volkzbitz.com

I will go ahead and post my experience from the last month and tonight as well as it seems to be inline with the OPs problems.
Been having issues with fuel spitting down the throat of the carb and gurgling with my new to me 71 super. It's a 1600 sp that was very well maintained by the previous owner. Has a newer (less than 2 year old H30/31 carb). I got her October 1 and drover her home from Tulsa, a four hour drive nonstop @65-70 mph. When I got home I could hear the gurgling in the carb/intake. Also the fuel in the oil caused my oil cooler seals to go. Also had a few times where it would hydro lock from fuel in the cylinders. She didn't like to start hot either.
So I started checking things. The needle was clean and I added an extra shim for good measure. The carb would continue to spit fuel down the throat after the car was off. The float is the black solid type and it passed the float test in hot water. So I changed the fuel pump as it had a small leak under the gaskets anyway along with the stand and shimmed it per the Bently.
Problem still happened.
So, today a friend of mine gives me an old German solex 30 pict 2 which had the solex float (brown and hollow) which I put in the newer H30/31. I did the float test again and it too passed. I compared the black solid float with the solex hollow float and the weights were extremely different. Lo and behold after installing the hollow float the problem is gone. Hot start issue is gone as well. Cranks and starts easlily the first time, every time now.
Bottom line is I think the fuel we have with the ethanol is bad for the new solid floats if they are allowed to sit for any length of time.
Sorry this post is so long but I thought I'd put it here for anyone else having these issues. |
I'd say you and I were in the same boat...! Thanks for sharing! _________________ Our 1968 Zenith Blue Beetle: http://www.thesamba.com/vw/forum/viewtopic.php?t=619501

Makes me wonder how many engines have been destroyed by these solid floats. It seems they fail in stages. 1st stage is hard hot starting and thin oil. 2nd stage is loss of idle after warm up.
I also wonder if the manufacturer is aware of this or if they care? My carb is less than 2 years old. Anyone with a solid float needs to be aware of it. _________________ 72 Super Beetle

It's pretty darn sad that these "new" carbs (like most "new" parts) are so shoddy quality wise. It also reinforces why so many folks are buying rebuilt/refurbished original German made Solex carbs.
All my stock VW's have their original rebuilt/refurbished German Solex carbs on them with their original 40-50 year old floats that don't sink. _________________ Contact me at [email protected]

I hear you. It's sad.
Atleast a hollow float will crap out all at once (usually in my experience). These solid types seem to go little by little as they become heavier.
This is my first carbureted vw in probably 12 years. The rest since have all been FI. This is my first experience with these solid floats as im used to either the white or brown hollow types. I can't help but wonder if it's sub par quality or if the blended ethanol fuels we have these days is killing the solid floats. _________________ 72 Super Beetle

Certainly the manufactures in China or S. America have to know these carbs will go into parts of the world were ethanol is used in the fuel. That's the biggest issue for me. Companies continuing to make and sell products that they know are shoddy. Think EMPI. _________________ Contact me at [email protected]

It's quite amazing that anybody can make a plastic float that lasts 50-100 years, but weber and solex did, give credit where it is due
On another Board, I and a few other fellows came to the conclusion that it's not JUST the ethanol that causes problems, more likely it is other small fractions of oddball chemicals that just happen to go along with ethanol. Same way hangovers are not caused purely by ethanol either, but just as much by the other contaminants in your beverage, point being, the quality of booze added to the fuel is not tightly controlled, and problems can be regional, and yet, these OE floats survive it all |

So the carb kit that I ordered from Carb Junky arrived in the mail today. After work, I decided to throw in the float, new gasket and give her a try. As always, she fired right up and the anticipation mounted as I waited for the choke to release. Once it released, to continued to idle like her old self. I let her run for about 15 minutes, throttle was responsive and no more rich smelling exhaust. I still need to adjust the mix as she’s idling a little high, but I also need to get the oil changed again since so much fuel had seeped into the case. I’ll get around to that on Friday evening. So for now, she starts right up, cold or hot and idles like her old self. Thanks to everybody who chimed in with advice.

Awesome. Feels great don't it?
Mine runs like a striped ass ape now too. Night and day. Amazing what those solid floats do when they go to hell. _________________ 72 Super Beetle

Nice job staying with it and methodically working through the problem!
I'm not sure if it was your camera's mic angle but it kind of sounded like your valves needed to be adjusted? Just an observation. _________________ Contact me at [email protected]

After running so crappy I'd recommend checking/changing the plugs and checking the valves as wcf suggested. That's on my to do list as well. _________________ 72 Super Beetle

Ok, one more update because I know somebody else will run into this issue...Got Mabel out for a long drive today (almost 80 degrees in Ky. in early November, love it) I decided that since I replaced the intake, distro rotor, cap, points, condenser, plugs, etc., I figured I'd go ahead and install new plug wires as well. After a half hour of driving, motor good and hot, she started back firing...not horribly, but I could hear it and feel the idle was rough. She did idle and ran good at higher speeds, but lower speeds, not so well...the back firing was the clue and I already suspected what was going on...Remember, I installed a new intake..I torqued it down with 14 foot lbs on each nut. When I got home, I left her sitting and idling. I took some starting fluid and sprayed the driver side around the intake and the head, nothing...sprayed it around the passenger side and she sputtered...bingo....I went ahead and shut her down to cool, changed the plug wires and re-torqued the intake...sure enough, the passenger side was loose. After I re-torqued, fired her back up, idle was fine, let her warm up a bit and drove her out on the highway for about 15 miles, no backfiring, ran fine. When I got home, left her to idle and sprayed starting fluid around the intake again, no effect. Looks like the intake just needed re-torqued....she's a happy camper and so am I... _________________ Our 1968 Zenith Blue Beetle: http://www.thesamba.com/vw/forum/viewtopic.php?t=619501
