|
| I have a progressive carb on a 1835cc sand rail and I am having problems with the carb linkage sticking open for the secondaries. I have cleaned the linkage with carb cleaner and I am not lubing it just leaving it dry. It will work fine until sand gets thrown up and gets into the linkage. Is this a normal thing for the progressive? I put a stiffer spring for the secondaries but I think the problem is in the linkage for the main's. I have not taken it apart yet to see if something is worn out in the main linkage. Is there an easy fix out there or a kit to fix this problem? I also have been thinking of making a thin aluminum deflection plate to block the sand from getting to the linkage, has anyone tried this approach? Thanks for any and all help. |

| Shield sounds like a good idea. |

| I was thinking about this and was wondering if there is a way to make the secondaries open/close with the mains so it is no longer a progressive but like a single 40/44? It is in a sand rail so fuel economy is not a big concern. Would there be a problem tuning the carb this way or do you think that it would work? Has anyone attempted to do this before? Thoughts concerns? |

If I am going to go with a new carb it will be the single 44. That is what I am going to try to make mine like. I don't know if it will be possible or what the tuning problems will be but I would think it can be done if I can figure out the linkage situation. I have a couple of ideas to look into to see if they will work or not. If anyone else has tried this and has a sure way to do it, I would like to know how it was done. I will update on my findings. |

| I will be interested to hear how that goes. I have a progressive that only performs well when the secondary is operating. I have to keep my foot in it so they may as well operate together. |

Do you have the carb tuned right? I know that these are a pain to properly tune/setup. I was lucky and seems that the guy that had the motor before me had it tuned pretty good.
It will probably be a little while before I get to this but might be able to get to it next week. I will keep everyone updated and will give the best parts list to my ability if all works. |

| OK I forgot about this thread but here is an update. I did attempt to "sync" the main and secondary with two of the aftermarket linkage kits for the 32/36. The flat spot on the butterfly's are not "clocked" the same so it didn't work out as planed. I still think it is possible but you would have to custom make your own circular cams that mount to the butterfly. I am over it and getting a single 44 for this car. |

| whenever i was into large scale r/c (1/5th and bigger) we would put o-rings on the outside of our carb shaft and cover them in dielectric grease and put a balloon over that to keep them from sticking when duning... may be worth a shot, just a one trip use, then wash the o-rings off, rinse the grease, and start again for the next trip! |

Thanks for the tip, I might of tried it before the last trip. I tried to make a shield and that didn't work either. I am sick of ruining trips because of this carb, I am getting the single weber 44 setup. |
