1969 starting issuses

[campdog2]

I have a 1969 VW dune Buggy. Engine only has about 7000 miles on it. I recently have been having problems starting it after I drive awhile. When it's cold it starts right up but after I stop somewhere and try to restart, it is very slow to restart. From trying to turn it over several times the battery goes dead. Battery is only about a year old. Is it a starter issue or is the generator not charging the battery fully? Any help would be appreciated!

Howdy ... and welcome

Try checking :

*choke adjustment
*too much timing
*dwell angle out of spec
*fuel tank venting
*vapor lock
*vacuum leak
*fuel delivery
*weak spark

Some here claim that is normal for ACVWs, it even mentions it in the owner's manuals. I have never experienced that in any of the numerous bugs I've owned - always starts right up & drive away immediately.

Maybe post what engine, carburetor, distributor, & etc you have.
Pics could help also, we like pics.

Verify charging system is working & should clean grounds just for insurance.

Do a load test on battery to rule out a dead cell. If it poops out after a few cranks that's not good. Check electrolyte level, unless sealed unit.
Fully charge battery, let rest 6hrs.
(don't be fooled by "surface charge")
Record voltage
Record voltage while cranking
Record voltage after cranking
Loss should be no more than 12%


Trying to help, good luck ... stay safe

Are you saying the starter turns the motor slowly, or it takes a lot of cranking for the motor to start running?

[campdog2]

Yes, the second start is slow.

I also replaced the carburetor. After all this began.

As jinx suggested, a systematic troubleshooting process is needed. Replacing parts without a confirmed reason to do so can get expensive and actually complicate the problem given the generally poor quality of many aftermarket parts and assemblies sold today. Posting several photos of the engine is a big help. It allows us spot things that are amiss that we otherwise wouldn't be able to point out.

Check out Speedy Jim's page on why an engine won't start. Even though you can sort of get yours running, the page is a great review of basic things to check.

It cranks slower when hot. I haven't had time for a load test.
