Baulking under load

[d123456789p]

Not used my 1302 for a few weeks, started her up as normal, reversed out of the garage, went to drive up the road and it baulked as if trying to pull away in 4th
Give it a few revs and a bit of clutch slip and same again with some popping and banging.

My first thoughts were the advance retard in the distributer not operating as it ticks over sweetly.
I eventually got to the end of the road with it spitting and popping so decided not a good idea to go out so had to limp back it idle speed.

Im not sure if this is the problem and if it is, how to check it or fix it.

Any help would be gratefully received

Can we have pictures of distributor and carburetor . What year is the vw . Also has it been tuned up and valves adjusted recently . Have you done any diagnostics .

[d123456789p]

The car is a 1302S 1971, the car was running fine 3 weeks before this point.

I can get pics etc if it will help.
There has been no tuning that i am aware of and I would not know where/how to start diagnostics!!

[mark tucker]

did you have it in the right gear? might be deal motor mount or shift joint....could be wet ignition, dead plug,bad wire,funkey carb, funked up carb.vac leek.oil on clutch.

[rayvwbug]

I agree with Mark. Are you sure you are actually in first gear? May need to adjust shifter.

[d123456789p]

Just tried to go out in it again to make sure I was not missing anything.

Definitely in 1st gear
Ticks over well so I don't think its a plug or lead
Carb ticks over sweetly
Oil on clutch would still rev mine just baulks down and pops/bangs/farts!!!

Not sure I understand the issue very well, but it sounds like the engine cranks, starts, but when you go to move forward the car dies.

Cars left out to sit for long periods of time, with the ebrake on can rust the brake shoes to the drums. This makes the car impossible to move. If that is the case you would need to break that bond with a big hammer or complete disassembly and reassembly of the drum brakes.

Had to deal with that several times.

Don't laugh- but did a critter move into and build a winter nest in your exhaust?
I don't know where Teeside is- or that's a fictional place near the Tee.

No, the issue is it starts perfectly, ticks over, I reverse it out of the garage then when I pull away but the engine bogs down as soon as you put decent load on it, similar as if I was to try and pull away in 4th gear (not that you would)

Parking brake?

Cracked distributor cap?
Points closing up?
Bad condenser?
Bad coil?
Plug wires breaking down?

I bet "Ticks over" is an automotive term many of us are not familiar with.

The solution to your problem is probably in the first reply to this thread. When was the last tune up?

"Ticks over" is pretty much the same as saying fires and runs, so "ticks over well" would mean it runs smoothly without evidence of misfire.

From the description my thoughts would be either the distributor isn't advancing correctly, the condenser is suspect or grounding out as the advance kicks in, excessive spark plug gap, weak spark due to bad coil/rotor/cap/leads/etc, or there is a speck of crud partially blocking a carb jet or passage.

Another vote to see if the distributor is advancing. Maybe the vacuum canister dried and and blew. It would certainly fall on it's face if that happened.

Pics of the engine and a listing of the carb model, make and distributor and number of it would help.

Hi guys

Teesside is in the North East of England.
'Tick over' is the same as idle
The car was running fine then this problem.
My first thoughts were the advance retard, it revs while in neutral but when in gear and trying to pull away.
Is a timing light the only way to prove/fix it.
If it is this......how would i fix it?
I can check the plugs in the meantime but I'm sure they are fine. Service was done in April

[d123456789p]

[wcfvw69]

That's an SVDA distributor. Single vacuum dual advance. What brand is it? The screws say it's an aftermarket, either a Mexican Bosch 034 or worse, Chinese copy of the 034. Yes, a timing light will show you if the distributor is advancing and how much it is.
