When I accelerate I slow down?

I slow down for the first few seconds when accelerating, no matter the gear I am in. Any clue to what causes this?

Does the RPM/engine go up but the vehicle slows? If so, sounds like clutch disc slippage, and then replace the pressure plate, throwout bearing, disc, and resurface the flywheel.

No the whole this slows down speed and engine. It back fires sometimes, Carb maybe?

Are you running a 34pict/009 combo?

Oh! and she shuts off some times when I hit the breaks. Solenoid maybe?

Take the cap off the distributor and tell us if you have a solid state electronic part in the distributor

If so -- what is the MF Name

Go ahead and take a picture of your whole engine and post it.

I think they are trying to see if you have points in your distributor or pertronix type electronic ignition .

Have you made any changes to your car recently?

Well you do have an 009 dist ( non vac. type). Take the dist cap off by prying off the two clips on the sides of the dist and take a close up picture for us, we'll be able to tell you if you have an electronic ign. or points and cond.( which I'm sure you'll be able to tell if you have points in there). Maybe a good tune-up is in order. A service manual will be a must. Also the "bog" you are esperiencing could be a simple adjustment of the mixture screws on the carb or ignition timing adjustment.

Well if you are running a 009, it really helps to time it correctly.....

http://www.type2.com/library/electrip/bosch009.htm

If you have points (and not a points replacement module like a petronics or something) make sure the dwell angle is set correctly before you adjust the timing. A point gap of 0.016-0.018" will get you close, but you want to see a dwell angle of 47º +/- 3º.

And be sure to have a look at the accelerator pump inside the carb (it is a little brass tube that squirts gas into the carb when you step on it).

No, taking the cap off doesn't ruin your timing. Put the cap on the way you found it, not turned 180 degrees, and you'll be back to "normal."

Go here: http://www.vw-resource.com/tune-up.html and start with #2.

You should probably get some literature. As an introduction, I'd recommend How To Keep Your Volkswagen Alive. It's not the most accurate or thorough, but it's a good basic introduction to VWs, air cooling, and motors in general, plus it's a fun read and has cool drawings. A Bentley manual is a more thorough source of knowledge, but it won't hold your hand and make you feel better the way John Muir tries to.

Edit: Oh, and as everyone and their mom will tell you, your carb and distributor setup isn't ideal, but you should still be able to get it to run OK if you know where to find and how to follow directions. Haters gonna hate.

Vwnewbie, when you put the cap back on you will notice a a little protrusion on the cap and a corresponding notch on the dist body itself (right on top) can't mess it up...well you can but look and you will see it.
Cap and rotor look clean, almost new looking on the inside. I do spy the dreaded fuel filter located by the 'ol dist. drama which you may want to relocate. First get the bug running right and check back and you will get a whole slew of answers on where you should put the fuel filter Wink

Well here is what I know,
The 34/ 009 was with the car when I bought it oh... 6 months ago. This is my first car and I have put a lot of work into it. I own a haines manual and the famous john muir book. I have put a lot of mileage on my baby and she has never let me down, just acted a little funny, at times. I am broke and do what I can. I try to knock out the small things first before I have a mental break down of," Omg my car is screwed and needs rebuild." Because I'm sure she does but I deal with it as it comes.

Now. What distributor should be on there? and carb? It will have to wait but if I know I can keep it in mind.

Will someone help me with my initial problem?

No I can not take her completely apart and leave her in the garage for a month so starting small is the best way to go.

Thank you.

Vwnewbie don't let this get to you, VW's are simple machines (as cars go) but if you are new to tinkering with cars it can seem a bit overwhelming at first.

Get the Muir book to start, it's not the greatest as a tech manual but it's got a lot of really good info and it's intended for people who don't know much about cars (actually as I recall it was intended to help hippies keep their VW's going!), so it's very laid back.

Read through this site, it's FULL of good info, and if you start feeling overwhelmed go do something else for a while.

Most of all have fun, these days that's what these cars are all about!
