Need help: My old LML scooter not starting after being idle for 3 weeks

It is a 1990 NV model that I have acquired recently along with a 1995 Bajaj Chetak.

BHPian spawndon recently shared this with other enthusiasts.

Hello, guys.

I have recently acquired two scooters, Vespa derivatives - LML NV 1990 and Bajaj Chetak 1995.

Not very knowledgeable mechanically, I have seen how to pull the side cover and clean the spark plug with a cloth on the Chetak successfully.

While trying to start the LML after 3 weeks, I found that it was not starting in one kick, so I did the above process but with no success, even though the spark plug became clean. Also, I can hear the turn-indicator beep and the gas-indicator needle seems to be jumping with every kick both in Key-ON and OFF positions.

I did the usuals, tilting the scooter towards the right side and holding for a few seconds, kicking in fuel-ON position and then after smelling gas, kicking in fuel-OFF position, but to no avail.

No mechanic lives nearby. All I have is the tools in the toolbox - hex nut, metal rod, screwdriver.

Any suggestions, please?

Here's what BHPian ObsessedByFIAT had to say about the matter:

There can be a lot of things which can stop a scooter from starting. A dirty spark plug is just one of them.

I would look at the following:

  • Do you have sufficient petrol in the tank?
  • Is it reaching the carburettor? Are there any traces of rust /grime / water etc in petrol?
  • Is the carburettor clean with a working float pin?
  • When you try kick-starting the scooter, does the current pass through to the spark plug?
  • Have you tried using a different spark plug?
  • Is the air filter clean?

These are just a few possibilities. Based on what the finding is, there can be a lot of different troubleshooting done.

Here's what BHPian anjan_c2007 had to say about the matter:

Reading your post I feel that being mechanically not knowledgeable as you say about yourself, it is not worthwhile to attempt DIY at this stage with your two-wheeler. Please search for a good mechanic in the vicinity and if he agrees to come to your place it's OK. Else, you can hire a three-wheeler to ferry the scooter to his workshop to get the proper jobs done.

The first job that needs to be done is to check the fuel system fully. Next the mechanicals including the engine and gearbox. And then the electricals. With all the checks and repairs as need be, hopefully, the two-wheeler could be back on the road.

Here's what BHPian SS-Traveller had to say about the matter:

You might want to take a closer look at this thread and troubleshoot accordingly. The LML 2-stroke engine is a simple system by itself, and there should not be too much effort required by any local 2-wheeler mechanic to get it running.
