  1. Let the motor dry out over night - carb open, plug out, fuel off and am going to put a new plug in today.  Was told by the folks at Scooter Speed about a particular shut down sequence on the stock models that I did not know about.  Basically shut the fuel off and don't hit kill switch to prevent fuel from sitting in float or flooding cylinder.  Let's see if this helps!  If not will replace float. 

    I tend to agree on the 12 volt upgrade.  Any suggestions as to which kit for an all stock motor? 


  2. Possible I am getting too much fuel in there. Tried this AM and plug was wet after a few kicks.  I did make sure to turn fuel off last night.  Took off air filter to look inside carb and seemed wet in there too.   What is confusing about this though is I drove her 3 miles 2 days ago no issues at all.

  3. Going to check the float and choke today. Will take some pix too. 

    Yeah I also have a Harley Davidson m65 Leggero. It's great riding up here.  Great roads, never too warm and the mountain scenery. 

    I actually know 3 places that would probably host us.  One in Manchester they used to do huge car shows, Stratton Mountain does events like this and their a town owned field for state fairs called Bondville Fair.

  4. My series 3 Li150 is driving me nuts.  

    Has a new top end, crank shaft seals etc.  Drove yesterday like a dream. Today I went to start it up no go.   I am getting spark.  Fuel has been a constant 1:32. Using a 7 spark plug.  

     

    Thought after all this work I was over this. Also to note it is an original 6volt system. 


  5. Was also reading this for what it is worth.   http://www.lambretta.co.uk/downloads/sparkplug.html

    We did experience a large change in heat and humidity in the north east

    Fouled Plug

    Wet fouled plugs are normally caused by rich air/fuel mixtures, these must be changed as the plug will not operate. The richness is more comonly caused by jetting, but can also be caused by an incorrect fuel to oil ratio. Fouled plugs can also be caused by selecting to colder grade in spark plug which will not allow the plug to burn the mixture efficently. Dry-fouled spark plugs can sometimes be cleaned by bringing engine up to operating temperature.

    Before changing fouled spark plugs, be sure to eliminate root cause of fouling. Running rich can also be caused by a number of other factors, Change in Ambient air conditions, altitude, humidity


  6. Since the bike is not in front of me and I am a rookie I will answer what I can. 

    The choke was off (after it warmed up) and it ran but I was constantly giving it a little bit of gas maybe more out of fear that it would die.  It is on coil and points not electronic ignition.  The only two things that really have changed are the outside temp and humidity and the fuel mixture.  This time the fuel mixture was done by me rather than the restoration shop.  So not sure if the richness has to do with the oil to gas ratio rather than the gas to air mixture even though I know they are all tied together!   But this is why I love the help this forum provides.  :) 

    Carb - Dellorto SH1-18/20 Carburetor - fully rebuilt, cleaned, new gaskets etc only 4 months ago with about 40 miles driven. 


  7. Okay update here.  She started after a few tries today in the driveway.  A lot cooler here but then after getting warm she died.  Pulled the plug and it was black and greasy. I did not have a spare handy but I cleaned the plug a bit and put it back and it started right up.  So what do we think this means?


  8. So my newly restored Li150 S3 has been running great. I had a full tank of gas in it from the shop that worked on it.   I just premixed my own and I thought I did it at 40:1 things seemed to be going well but then towards of the end my ride last night she stalled out coming up my steep driveway (in 1st gear) and then even when I got her to fire back up she would not make it up.   A few things to note. 

    1. When I started it cold that day she was producing a lot of smoke but then when warm was fine. 

    2. It was really really hot here. Like 100 outside not sure if that would be an issue. 

    3. When I originally tried to make it up the steep driveway I had my 150 lbs brother on the bike as well.  But then on second attempt it was just me and did not make it. 

    4. I am using Castor 927 Pro Series as my oil

     

    Appreciate any advice for this newbie.  


  9. I have a stock LI150 S3 that just got finished a restoration.  No mods or anything. 

    What do people suggest for fuel?  Pre-mix like you would put in a chain saw or small dirt bike or mix your own?  I know asking about premix might shun me forever but just looking for some advise.  😀

     

    If you do mix your own what ratio is suggested and any lubrication preference?  I believe LI 150 is 2% ?  


  10. Hi

    I have a 1962 series three that I found in the Bronx years ago.  I am doing a full restoration on it now and found the original paint was a white and blue which made me think maybe it has some NYPD history or NJ police.   What is easiest way to figure that out? 

    Thanks.
