Puolilämpimän auton käynistusongelmasta saat irti kun laitat kaasutimen ja imusarjan väliin lämmöneristyslevyn, vaika tästä:

Jos sulla on Solex kaasarina, niin pitäisi menna heitämällä, kun Weber DGV pulttijako on samaa. Tietysti on sellaisen levyn itse tekeminenkin helpo, teollisuusmuovista vaikka.
Omalla oli sama ongelma viime kesällä, nyt vaihdoin kaasarin DGAV'n ja laitoin samalla lämmöneristyslevyn - starta hetkessä
The usual problem is that the whole engine gets thoroughly hot, and when you switch off, there is a 'heat soak' period when the temperature in the tinware and engine compartment rises because the residual heat in the cylinder/heats isn't getting blown away by the fan. The heads run at about 265-285oF (130-140oC) and can run up to about 355oF (180oC) on a really hard run which is pretty hot.
This causes the metal fuel line around the tinware, the fuel pump, and the carburetor to all heat up somewhat, causing either excess vaporization of the fuel in the carburetor, or and actual vapor lock in the fuel line or fuel pump.
As a result, starting is sometimes hard. With hot fuel in the carburetor, the least reduction in pressure (through the carburetor throat) causes instant vaporization, perhaps of fuel in the float bowl too (which breathes into the top of the carburetor throat), and of course a vapor lock in the fuel line or pump is even worse, because it will result in an empty fuel bowl in the carburetor - the car uses that fuel and stalls because it can't get any more. Then it takes a lot of cranking to fill the fuel bowl, once the vapor lock itself is cleared.
Kylmänä ja kuumana taas hörähtää vallan mainiosti.
