New project...

[kennypinkerton]

Just recieved a new to me carb! /ubbthreads/images/graemlins/grin.gif Thanks Doc. Needs a good cleaning and I'll try it out on the MGB /ubbthreads/images/graemlins/thumbsup.gif Interesting choke mechanism. I pushed the piston up and sounds like there's some of that florida sand in there. /ubbthreads/images/graemlins/eek.gif Of course it stayed up. Oh well... I'm gonna have fun with this one /ubbthreads/images/graemlins/thumbsup.gif

Puh-lease... That bread-tie is an indication of fine craftmanship and care.... Just man-up and bolt her on! /ubbthreads/images/graemlins/smile.gif

Is there a grease of some sort that you should add to the groove that this piston rides up & down in or is it metal to metal?
I would think that a shot of lithium or somthing should be used but you don't want it to cake up over time.

What does everyone use?

 

[jsneddon]

very close tolerance metal to metal. No grease. And don't go crazy sanding them either. If it is sticking you've got a cleanliness problem or a "ovaled" dashpot, mis-aligned needle, bent damper rod, etc etc etc. Grease is not necessary. On a good working one you'll get a very satisfying "clink" when you push it up all the way and then let it drop.

 

[kennypinkerton]

There's some crud in there... I could feel and hear the cruching of dry crud when I lifted it with my finger... and it stayed up (I only went about halfway)... I think it gets lubed by the dashpot oil.

Weird thing though is there are 2 fuel nipples on the float chamber... I'll need to take it all aparts and clean it up good... something for tonight when Julie's on the computer /ubbthreads/images/graemlins/thumbsup.gif

 

[Nunyas]

*refrains from making comments about the float chamber*

 

[kennypinkerton]

Oh, well... I couldn't wait to play with my new toy... so I took it apart and cleaned it all up - Wow /ubbthreads/images/graemlins/eek.gif what a simple carb! piston now works very nicely. /ubbthreads/images/graemlins/thumbsup.gif

...and it's a little prettier too...

 

[kennypinkerton]

Does anyone have a closeup of how the little damper piston is supposed to be assembled on the shaft? Mine is very hard to insert after I put oil in there.

 

[jlaird]

Yes, will be tight as you push down and oil leaks past the plunger, but should not be a big deal. If so the bypass is pluged, dirt.

 

[DrEntropy]

Nope! I scrubbed it and cleaned it out a bit. It has all the bits and just needs a good rebuild. The damper SHOULD be hard to put in with oil: that's its job... If not, it's shot. the second outlet is because it's the "first" in a pair and the "twin" is supplied from the other tube... Rob has its "twin."

That dirt is Genuine Florida Dirt! AKA: SAND. Chaos and Mayhem PTY., LTD. are pleased to supply your gritty needs /ubbthreads/images/graemlins/grin.gif Sorry 'bout that. I scrubbed the crud off'n it and partially disassembled to insure it was "all there." The carb bits, not the grit. I didn't notice it'd been "contaminated."

 

[DrEntropy]

The damper is assembled correctly, BTW.

That bread tie was to keep the throttle plate from harm in "passage"... he also got some sections of pool noodle. /ubbthreads/images/graemlins/devilgrin.gif

Lime green! /ubbthreads/images/graemlins/grin.gif

 

[Nunyas]

saweet! I still got my sliced up noodle aroud here somewhere!

as for the plunger:

I've not deployed mine yet... waiting to see if I hafta go visit a butt sniffer this year. Plus, mine needs rebuild. The jet tube at the bottom was a little on the brittle side... /ubbthreads/images/graemlins/smirk.gif
