Vespa pk50, malossi 136 and Carburetor kit MALOSSI Pbhl25

my engine will not run very well. it runs on idle, but not on speed

Should this be installed?

But if I buy it anyway, which flywheel weight should I have?

 

I have 105, what do you think? I have malossi 136, malassi phbl25 and polini Evolution.

One more question. (Piaggio ape50)

When I shall change the bearing in the crankcase fan side, shall l put the new bearing into the fancase first and then put the crank into the bearing??

 

Or maybe you could explain me this?

 

Thanks

Hi

 

 

I think that the best way would be to fit at first the bearing in the engine casing.

 

 

cheers

ok

I'll buy a PARMAKIT for my engine. It has electric start. Which set should buy?

I use airfilter like this: Art.Nr. P2030063

and I think the ignation is fixed perfectly.

Tomorrow I get my "CDI ignition unit AddOnV",  what ignition should I have before the installation of it?
kkh

Should I buy this: "CDI ignition unit AddOnV Vespa"?

Hi

 

Of course man - the ADDonV is awesome, much cheaper than a complete racing ignition like parma or vespatronic.

 

 

 

But also a Parmakit ignition could be a solution because you can choose different flywheels weights and the quality is very good.

 

 

 

By the way im not a friend of the HP4 Wheel !

 

 

cheers

Hi

 

105 should be ok, but please check the "sparkplug color".

 

 

cheers

I do not get my engine to run at rpm. I get no more than about 5000 rpm. It runs fine at idle.

The setup is:

MAZZUCCHELLI Full circle crankshaft Vespa
Malossi 136cc
malossi 25, 108jet. (spark plug brown)
17 degrees ignition
Übersetzung 24/72

I do not understand what is wrong.

Hi,

it sounds a bit that your engine couldn´t "breeze", what airfilter do you use ?

 

Are you 100% shure that the ignition is fixed perfectly ?

 

cheers

Maybe I have the wrong spark plug? I have Bosch w3ac.

Hi dude

 

please notice that the parmakit is not for e-start.

In your case it´s the best to use the addonv.

 

 

cheers

Hi dude

Yes youre right - you have to install this part, its the venturi sektion.

 

What jet sizes do you have in your carb ??

 

cheers

ok

Hi dude

 

I recommend you to change the airfilter with this filter 40330000 otherwise your engine cant breeze enough air !

Please try to fix at first the filter problem and then add the Addonv !

 

 

cheers
