914 things..... need help

Um, hello all! College student with a have-to-daily-driver 914. Car is bucking every once in awhile at all RPMS, had a problem with Fuel Pump Relay continunity, seems to not switch unless positioned a certain way. I tried spreadding out the contacts on some pins, do I need a new relay or what? Also, how hard is changing out the condensor? I changed the points and I have heard the condensor shoudl go as well. Please help?

de-fuzz teh end of a Q-tip then wrap it with a little pc of fine sand paper. Radio shak sells contact cleaner that works well also. If it is really nasty, just take the relay board out of the car to make it easier to do a good cleaning jog. Its only held in by 2 screws

relay board

have you heard of soldering those rivets in the relay boards, i have never seen one out of the car and with the tar taken out, but I assume that all of them were riveted?

You should also check your timing. Too much total advance (vacuum + mechanical) can cause bucking in all gears.

although I was only addressing teh electrical issue, Guy has a very valid point. always check the cheap or easy stuff first. I re-did the joints on a relay board once but it is a time consuming affair that might not cure a simpler problem. air cooled engines can be severely damaged if the timing is off.

Just set it actually....it ran fine until the relay stopped working....but right now i have the retard disconnected as the AAV doesnt work at all (closed all the time) but maybe i need to hook that up...just doesnt like to run with the host connected to th retard (and yes when the retard is unplugged the hose is plugged)

it can sometimes be a real pain in my-you-know-what, but i do have a 2.0L D-Jet '74 with the FI system still going and going with the occasional squibble. what about yours? most people dont like fooling with the FI so they get carbs...i am just worried about gas milage....heard it kinda sucks

I advocate keeping the FI unless you have a hyped up stroker. My daily driver is a 72 1.7 D-Jet. My previous daily driver was a 74 1.8 L-Jet. I really liked teh L-Jet car. My fun car is a 73 with a 350 Chevy. the first thing I do with my FI cars is go through ALL the FI connections and clean them. My 1.7 gets close to 30 mpg if I keep my foot out of it

yeah I would do the same but i simply dont have the time....taking 16 hours of classes and working 20 hours a week is something I am definately not used to. Good news is that I am studying to be a mechanical engineer, so I'll be able to make parts when they break I am saving that for a nice summer month or so....

the only thing that scares me about the L-Jet car is the backfire issue.....is it really that bad bc i have heard that L-Jet is actually better in some ways..

I removed my relay board, chipped out the tar (what a mess!) and checked all the connections. I resoldered a few but it was apparent that the "repaired" connections were no better than the aged ones, and I nearly melted the plastic ridge separating some of the circuit paths in a few spots, so I stopped. There is a diagram that shows where the relay connections exit the board at the multi-pin connector near the firewall. I believe if you really suspect a bad board you should do some continuity testing to see if the circuits are good. I don't think the effort I put into rebuilding that relay board had much value.

yeah a high-watt soldering iron will do that... I have a 40 watt and a 15 watt, which is good for small stuff. My dad actually has a 100 watt iron. I might as well just set the relay board on fire....lol. that tar is a mess, but if relay board repair doesnt do any good I will move on to the relay. it DOES work and it is sealed but I have a new relay waiting for me in Louisville....hopefully. so i will try the contact cleaning then the new relay then the relay board repair

well the VW guy who i got the car towed to ordered another relay for the relay board. but he switched them and it worked fine. it's only making most-of-the-time contact. the socket is rusty so I am going to clean that off..
