Capacitor = condenser.

Thank you Master!!!

Yes!!

It's still not running right. Idles great but serious flat spots when i try to accelerate!!!

got it. I thought Condensers were either good or bad? I didnt know they could be ' kinda' not functional

I've seen them cause high rpm missing.

The electrolyte and or conductive substrate can break down. Instead of storing a charge it can leak through.

Last nights actions.

Since the rebuild carb was installed the engine is idleing fine but i was having trouble with acceleration so the first thing i checked was to see if i had a good stream when the throttle was juiced. There is a nice stream so that is not the problem. I decided since i had changed the timing i wanted to go back to the old carburator to see if that still had a problem, which was no idle, but strong acceleration. With the old carb it still won't idle but the acceleration and running at speed is fine, so this elimiante the timing as being an issue.

Back to the rebuilt carb, adjusted the volume control screw but i still have a bad flat spot when accelerating and it stuggles to get up to speed. This tells me it is something in the carburator, but what?

I took it apart and the main jet in the carb bowl is clean and the same size as in the old carb. I removed the air injection tube and that is clean.

Any suggestions on what part of the carburator might be casuing the problem I am experiencing.

When i rebuilt the carb i removed everything and let it sit in a can of caruberator clean for about 30 min, then washed it out and blew out all the orifices with compressed air.

I'm stumped. I quess i could try rebuilding another carburetor but i would like to know what is causing this problem.

keep me posted Ken. I have 2 freshly rebuild carbs from TS, both of which are dogs now. My slammed thing used to spin the tires around turns, now is a pig. The baja cant go over 55. I think its bc of the carb on both points. I have a few carbs I'll glass bead and clean out, but time permitting. I know minimal about the solexs and wish to also broaden my horizons.

Will do! I'm going to see if i can find something on the workings of hte Solex 34 PICT/3 Carburetor.

since keifernet is longer reachable...i would suggest you let ed rebuild your carb...There is a little more to it then just installing gaskets and jets..
it is worth the money...even if you stored the carb without gas and you did not relax the carb pump it will not run well

Glenn and Matt thank you both! Although your advice makes a lot of sense and if it was a daily driver I would do it.

part of me wants to know what it is that is causing the problem I'm fairly confident the problem with the carburetor that will not idle is a worn throttle shaft/bearing surface but i would like to know what is causing the other to not run at speed. I'll plod along some more and always consider the professional rebuild as an option.

By the way Matt, unless i am reading it wrong the site you referenced does not rebuilt the 34 Pict/3, only the older style. This is disappointing because they look like a great company and i like what they do.

Thanks Again!

It's your accelerator pump. Make sure the tube is pointed in the middle of the carb throat and not touching the wall. Make sure fuel is not seeping out of the pump on the side where you replaced the diaphram. Make sure the little tube is not clogged and that it is tight in there. There is an adjustment on the pump rod to increase or decrease the amount of fuel pumped, crank it up and see what happens.

I'll check it out! The stream does look strong but maybe the tube is not in the right place.

I'll keep everyone posted.

Maybe it's a prostate problem.

Who's going to reach up into the muffler to check?

Gynecologist mechanic:
A gynecologist was getting tired of his job and decided to switch careers. He'd always enjoyed tinkering with truck engines, so he enrolled in a school for truck mechanics. When the class ended the students were given their final exam: strip a truck engine completely and reassemble it in perfect working order.

The gynecologist did his best - and was amazed to find he scored 150%. "How could that be?" he asked.

"Well," said the instructor, "I gave you 50% for taking the engine apart. Next, I gave you 50% for reassembling it - a fantastic job, really. And then I gave you a 50% bonus for doing it all through the exhaust pipe."

I pulled the carburetor off the car removed the top and adjusted the accelerator pump tube so it squirts unobstructed down the carburetor. I also swapped the pilot jet from the other carburetor into this one but i'm still having a acceleration issue and also running at speed.

I'm stumped about what else could be causing this problem!!!

the solex issue continues. Keep us posted on your ideas to resolve it.

I figured out the problem with the idle on one of the carburetors. I read on TheSamba that it is not unusual for people to over tightened the Pilot Jet which is also called the Idle Jet. I think this ends up cutting off fuel flow at idle. I loosened the pilot jet about 1/4 of a turn and it idles very nice. I just have to apply some sealer or something to hold the jet in place.

I still have the acceleration problem on the other carburetor but one step at a time.

I think there is an o ring that holds the jet in place. Is it missing? Could be a place for a vaccum leak too.

No o ring for the Pilot jet. i read about some guy who modified the end of the pilot and others who cut the nub off so i'm still playing around with that.

Are you talking about the modified pilot jet or pilot jet in general?
