 Posted: Tue Mar 11, 2008 7:52 am Post subject: 28 Pict return spring |
 |
|
| I've searched all over the place for an answer to this question, and haven't really gotten anything that really helps. My problem is that I am fitting a 28 pict to my 40 horse and don't want to/can't use the stock tube/spring/cone setup. It's a long story, but in the end, I have decided to just figure out how to put a return spring right on the carb. I know that other people have done this, any ideas or comments? Can I use a later model throttle arm from a 30/31 pict? Any help would be greatly appreciated! Thanks! |

| I considered that, but I kinda wanted something more permanent. |

No... the arm you need would have to come off a 28 pict 1 or a 30 pict 1 that was set up for the "late style" return spring and not the early style on the long accelerator cable guide tube.
The tops of those style carbs also have a threaded screw hole and screw that held on another bracket for the return spring. You can get by with making one off the front screw that holds the top to the carb body though.
You can see the arm I am referring to in this pic I dug out of the classifieds...

You could swap over the top from a 28 PICT-1 if you don't mind that, it was a factory approved upgrade to get the new-style choke.
The later tops have a "stop" to hold the bracket in a certain place as well as the screw keifernet mentioned but the bracket will stay in place without that stop... most of the time.
You can see the edge of it here on a 30 PICT-1:

| A close up of a 28 that has been modified to have a return spring on it would be great too. I've seen some in pictures taken further out that appear to have a spring running from the throttle arm to a little bracket on the back driver's side screw on the cab bowl? |

Are you referring to my engine? Yes, the points and condensor may have been changed at some point. I also replaced the fuel and vacuum lines for safety. I can check the condensor for Bosch-ness if you wish.

None of the 28PICT or 28PICT-1s had the late style return spring. That was the 28PICT-2 carb that was so equipped.
Another thing with the late style return spring, is you cannot just bolt that arm onto an earlier carb - the "flats" of the throttle shaft are at a different angle on the earlier carbs. Compare how they attach at the throtle arm between this 28PICT-2 and 28PICT:

| yeah because i have a 28PICT 1 and it didnt have a return spring so i took one off my 30PICT to use and it wouldnt work because there wasnt a way to mount it so i used the cone/spring type that was used on the 28PICT 1. also, my carb leaks fuel where the arm is going through the carb to the oher side on each side , is that normal ?? i put a rebuild kit but nothing to do with that "through shaft" type part. ? |

| To fix the loose throttle shaft. you'd have to remove the butterfly and the valve, then have the whole carb body drilled out, brass bushings pressed in, and reamed to size. Not something most backyard mechanics are set up for. |

no, leaking fuel is not normal, but it is common at least for a little while... 
Actually that green wired condenser in Ev's distributor could be Bosch their newer condensers often have green leads. |
