2C OS not 2B OS. An OS 25 FSR Question.

Hi all,

Please pardon the terrible title, but it played right out of my fingers without even thinking.

Today I received what I was told was a new in box 100% old stock OS 25 FSR as seen in this link. Unfortunately it is not as described and someone has put a used and stuck OS 2CB carb in the box. It should have come with a new OS 2B carb. The two carbs are very similar and this mistake would be OK if the carb actually fit the engine but it won't because it is intended for the larger bore of the 21 FSR-C and 21 FSR-M. The seller claims no knowledge of engines and, having asked, he does not have a 2B carb to send me. Apparently he got this in a large lot of old tamiya buggy stuff which explains why the carb has been swapped out with a buggy carb.

Other than this the engine does genuinely seem to be unused though it shows a fair amount of wear and some discolouration on the case where someone sprayed some oil on it which is unfortunate. So to my question, does anyone have any ideas how I can rescue this situation or should I just return the lot to the seller? It was an eBay sale and I bought on the basis that it was described as new and therefore complete.




Thanks,
Simon

Simon, if what you received is NOT what was offered, I would return it. I don’t know the difficulty in finding the correct carburetor, that may be a factor. If they are rare and hard to find that would push me towards returning for full refund. If they are relatively cheap and easy to obtain, I’d negotiate with the seller to offset the purchase price to make the engine “ new” as offered. Sellers tend to not want a negative feedback from buyers.

That’s my
