After having lackluster results cleaning and soaking my daughter's TRX90 carb I decided to just buy a new one. I thought it was a 2005 so I ordered 16100-HF7-A11. Ten minutes later as I was reading and looking at pictures I realized I had a 2006 which has a different looking carb.... 16100-HP2-671 or 16100-HP2-672 or 16100-HP2-673. So now I am trying to cancel and replace order. Just an ongoing frustration with dealing with this carb. It ran perfect until the petcock starting acting up by not allowing me to turn off the gas 100% and run the carb out of gas after riding. So ethanol free gas still screws up the carb if it sits for only 2 months! Great. Yeah, I can always take it in to the shop and spend who knows, 300 or 400 dollars for somebody else to just do the exact same thing I am doing over and over until it finally works right. Very demoralizing.
DEFINITELY OEM HONDA. I would not even go with chinese if it was free. I screw things up bad enough when I do everything right! I will update progress as to the supplier (ebay seller) and the actual end results. I might even make take pics and post as I go in case I still need help after I get it installed and it might help others in the future.
Following up... I put the new oem honda carb in and it runs smooth and perfect with no effort or tweaking or setting. So happy with the results I am considering buying a new carb for my sons crf70 just to have it ready for the inevitable. $100 is not bad for being able to have it run perfect with 20 minutes of effort. Seems to make more sense than rebuilding and rebuilding and still not having great results.
