Hi,

Have been having trouble with my girlfriends ra40 stalling. It's an automatic and at first the problem started happening in gear when stopped, so I thought brake master cylinder, vacuums or torque converter. But checked all the vacuum lines and they seem fine, replaced o ring on master cylinder so that's not leaking or anything.But now its started stalling in neutral too, it's not idling at all anymore. Thinking carby or something could be the problem but not sure. Just after any tips.

Cheers, Jake

Check the point gap, they may have closed up.

I'm assuming it's got points?

yeah- check the points gap, preferably with a dwell meter as they give a more accurate answer on used points. maybe fit a new set if they are badly burnt, then check the timing.

 

If it still stalls then check the carb- can you sort it out with the idle mixture and the idle speed adjustment screws, or if not, can you pull the carb apart and flush out the idle system using a syringe and some petrol??

Don't really know what to do with the points, I don't have a dwell meter and don't really know what I'm checking haha but I'll read up and then check it out, cheers.

Simple enough, but fiddly as you can only read it with the motor running, then adjust it with the dizzy cap off, then read it again to see if you have it right, then take the cap off again to change it ... Feeler gauges you just set with the cap off then you're right.

 

However points burn metal from one side of the points and deposit it on the other, which is why they now put a hole in one side of them. This gives a wrong reading if you push a feeler gauge between the volcano and the hole, and your points will be too wide. Not a problem with brand new points, so if you have feeler gauges just buy new points and a new condenser.

 

The condensor (which is a capacitor) stores the electric charge until it discharges through the points, but an old condensor leaks power away and causes the points to burn. The other major point of wear (Ha! Great pun!) is on the rubbing block that wears away rubbing on the square dizzy cam all the time. This closes the points gap, retards the ignition and kills performance and idle speed. So always put a spot of grease on the dizzy cam with your new points.
