Throttle closed, there is no flow from the ports. As the throttle begins to open, first one (very small) port is now "below" the plate and so has vacuum pulling fuel from the pilot jet. As throttle plate opens (moves "up"), more ports are exposed. Jim |

When you said above I thought as in roof, whilst they are on the floor(If the carb was horizontal.. Which of cause it is not.. My bad, thinking of horizontal here, as in all the carbs I deal with at work... J. |

That evening I went to the shop to buy me some jets... Unfortunately he didn't have had any but i went up reading a book about the carbies. I have a 31PICT-4 which is, to what I read, pretty unusual. The difference (there might be a lot more) is the acc pump įnd on a 31PICT-4 there is suposed to be some kind of thermo device mounted with a bracked on top of the carb pusshing the trottle lever open (like the shoke does) without actually moving the shoke. This device is non electrical and is suposed to work on temps below 15 C. I hope I do make some sense.. Since I'm not able to trace the device down, I've got myself a 31PICT-3. Smaller pump and without a big brass bold into the reservoir. Is this the only difference? Before I change it, I still do want to clean the original up, having had advice here on how to do it. And where to look! Thanks all for your input, it is VERY helpfull Roger |
