Hi Carbymaster, as we all know this has been a problem for a long time but this will only succeed if the price is right. Going to be interesting what pricing you come up with because replacing the primer cap is going to be the killer here as we are all frugal people here and hunting a bargain is part of the fun. The primer caps are floating around on ebay for about $15 each, are yours going to be a similar price? If so plus the needle at $8 gets it up into the not worth repairing range I think. Might be a few people prepared to pay that but the fact the float needle is the reason for these motors not starting is really only known to people who have really studied these carbs. Personally I feel the market for these is probably quite small.
