1300 Toledo acceleration problem - please help!

[stevetheartist]

Hi all,

I've had tolly for just over a year and have done various bits to her just in keeping her running and maintained. This is my first classic so I'm essentially learning as I go, but this one is baffling me and I don't know where to start really.

She has become more and more jerky on acceleration. It started a few weeks ago. I havent been on long drives recently, only short journeys so I thought the battery was dying. But I charged it and it said it was full. Ive cleaned the carb, and in checking things pulled the tube out of the fuel float which came out very easily. The rubber holding it in was decimated, so a new one of those ordered and fitted, but she's still jerking- more than ever if anything...

Pressing the accelerator pedal down half way she accelerates, but any-more and she dies. Its like she can only get up to a certain amount of revs. and then something happens... such as lack of fuel?.. and suddenly looses all power.
The jet tube into the carb is bent/ creased. would this cause that serious of a fuel shortage? also could it be the fuel pump not working properly? ... I'm going on my guess that the engine is choking from lack of fuel.. but am I wrong in this assumption? Is it some other problem?

Ive changed the spark plugs recently, and up graded to electronic ignition instead of points, and replaced ignition leads.

Any suggestions/ advise is much appreciated. Thanks in advance!

You might have to replace your needle as well. Shouldn't they be repalced at the same time as the jet as they wear together?

Shouldn't this thread be in the "Dolomite Related" section?

Sounds like fuel starvation.

Try cleaning the filter on the fuel pump if you have that type of pump. But these do have a limited life so be prepared to buy a new one.

It does sound like the old jungle juice is not getting through properly sir...! Check the fuel filter and change it as a precaution, it is better to do this really... I'd check the fuel lines for cracks/holes as this will obviously cause a problem... It may also be worth draining the fuel tank, taking it off and giving it a good clean out as any muck in the bottom of that will get pulled through the fuel system causing no end of troubles...!!! I do hope you get this sorted as a Tolly is a joyful thing to drive when it's on song...

A weak coil can display similar problems, the spark finding it ever harder to jump through a more dense mixture as the throtle is opened further...its got me before.

When it starts doing this pull the choke out and see if that helps. If it does then you can say it is fuel stavation and at least you will know where you are aiming at to rectify the problem.

I had this on my 1500 years ago and also went onto a electronic ignition but it only helped a bit so striped the carbs and replaced the needles and was ok after.If you run on a nearly empty tank you can get alot of **it into the carbs.
