2nd Peugeot Speedfight 2 in Halifax

Post by willowglenn »

Hi,
running out of options to get my 2nd Peugeot Speedfight 2 running properly.
I suspect there aren't many Peugeot owners on this site, but I suspect my problem can be solved by a general scooter expert...
I just purchased a 2009 Peugeot Speedfight 2 LC 50.
It was new (14 kms) but had been stored for 7 years, so the gas was crap.
Drained the tank, put new gas in with treatment.
Only would idle, die when trying to accelerate.
Checked the vacuum to the petcock, it was strong, but changed the petcock and the fuel filter anyway. No improvement.
Took the plunge and took the carb off. Float bowl was full of crap.
Cleaned it and the jets properly. Now it will accelerate for about 4 seconds, and then die to an idle.
Seems like fuel starvation, but can't figure it out.
Next step is to pull the plug to check its color (shut off exactly when it stops accelerating).
Any thoughts?

Replace all the fuel lines and add an inline fuel filter(clear would be best) then run again and see if anything ends up in the filter. But it does sound like it has a clog somewhere along the line. Sometimes it take awhile to make sure all the crud is out of the system after a prolonged storage.

Replaced the clear inline fuel filter when I replaced the petcock.
The old one had a little gunk, but not bad...

With the carb rebuilt for the 3rd time, it ran like a top for a week (80kmh).
Now it bucks. Full power for 2 seconds, dies, full power for 2 seconds, dies.
The clue is that the engine oil light is on the whole time.
There is lots of oil in the tank, and the engine is not seizing, so it's confusing again...

Is it possible that you have an oil level sending unit that is failing, telling the scooter that you are low on oil ? ( when it is not low on oil )
Is it possible that your scooter has a system that protects the engine from seizure when the oil is low ( or thinks it's low) and cuts engine power to protect the engine ?
I think you should fix the low oil light system first then drive it to see if this is the issue.

I was thinking about a low-oil spark cut possibility too.
The CDI box on these scooters also tells the electric oil pump how much to send.
On a hunch, last night I took the CDI box off my other Speedfight and put it on this one.
It ran perfectly.
Now I just have to convince the European ebay sellers that a small $40 cdi box shouldn't cost $60 to ship to me.
Thanks for your thoughts.

It is always good to hear of progress, especially when it comes to intermittent issues.
