Well I bought a carb kit and thought I could re-built it with no manual and zero mechanical no how. That plan didn't work out! As I was testing on the IRL I ended up losing a few parts in the water and made it back to the ramp with some help from an old A-team episode I remembered. Anyway I took it to my local place I use and told them the following: 1) I had a list with order numbers of the parts I lost 2) Told them everything was fine with the motor until I tried to re-build the carb. The butterfly was not opening all the way on the throttle and I was getting about 10mph loss in speed unless I manually opened the throttle up. I was not leaking any gas however. 3) So I made sure they understood that the carb was messed-up by me and I did not touch anything else on the motor. I left the boat/motor and about a week later the service guy calls me and wants to confirm what the problem was and I made it clear that the carb was the problem and I did not mess with anything else. Yesterday I get a call from him saying that they got the "inexpensive" parts in that I lost ($50) and would begin to fix it. They have had my boat/motor for 2 weeks now. Today the guy calls me and says I really F******* the carb and I would need a new one because of the spring/needle/ball bearing "THING" was broke and that small piece could not be ordered alone. He then starts to tell me the damage! He says he spent 3 1/2 hours trying to find the cause of my problems with-in the carb @ $80 per hour and can't really tell me why my motor will not run. Soooo I have $280 in labor + about $50 in parts and he says a new carb is about $300 + labor to install. I was slightly pissed and don't know if this is right! This place seems honest, but why didn't they just re-place the carb instead of spending so long trying to fix it when he tells me " I have never seen a carb this messed up" I don't want to screw anyone, but this just sounds stupid to me! ANY IDEAS? The work order said per my request "If the charge to fix this labor/parts is over $300 please call me first. BTW, this is a Mercury 2003 15 hp 2 stroke in very good condition.
