Will my scooter not start due to leaking air?
Hello,
I'm currently repairing a Speedfight 2 LC and have encountered a problem. After completely rebuilding the engine, the scooter won't start anymore.
Gasoline is reaching the carburetor. The ignition spark is there. The electric choke is working. The engine's compression is also correct.
Well, today I made a final discovery: the seal between the carburetor and the intake manifold isn't completely tight (though it's not loose or anything like that, just slightly leaking), and now I'm wondering if that could be the reason why the scooter won't start. If not, what else could be causing it?
Thank you very much for the answers 🙂

Certainly not because of a little false air, even empty gasoline feeds can be the cause(underpressure), try to spray the following,Startpilot/Bremsenreiniger directly into the air filter/gasifier, if this is not available, out candle and spray a little gasoline into the cylinder!
Thanks for the answer I’ve tried everything anyway
Completely disassembled engine, KW bearing and simmerings changed, new piston (correct, after marking) installed, ring impact play of the piston rings measured with the sensor gauge, piston rings mounted properly around, squeezing edge checked/measured with a piece of solder tin, ignition and gasifier set….just to name a few important points.
Then it can really be on the false air, because the window for ignitable mixture is quite narrow.

Thanks for the answer yes I have already thought at temperatures that can already be

Well, if that’s the mistake…
Did you check the spark? Ignition correctly set? Come on, gas? Is the float okay and the chamber doesn’t run over? Did the carburetor equipment change?
In addition to false air, these points are also not insignificant (small cause, great effect)
Okay, gasoline and sparks are okay. Is the ignition time right?
Do not know exactly how to control that I will try this morning at daylight and then again thank you for the idea
In any case, as soon as it is leaking or even licking, it does not work.
I’m sure he’ll start again.
Of course, the part draws false air, so right in which there is no gasoline, so tell how to do that part then, yeah how?????
First change seal. And then keep looking.
So this could be the reason?
Yeah, what do people write to you?
Yes logical.
