Hello. I am trying to help out a friend with his Sportsman. I'm not with the machine and when I get up there, Internet will be spotty at best, so I'm trying to gather as much info as possible beforehand.
What I know is that the engine would idle fine, but it got progressively bad where when rolling in, it would bog down. Eventually, you couldn't drive it all. He took it into the dealer and they rebuilt the carb and it was quite a bit better, but not 100%. He drove it awhile and it started getting worse and worse and now it's back in an undrivable state.
He cleaned out the tank and line and (I think) installed a new filter. He also replaced a fuel line to the pump due to a leak.
Is there a way to check fuel pressure? From his description and his feeling is that it's a fuel problem, but what if it isn't? Could it be something else like timing? (I'm not familiar with these things, so bear with me and any irrelevant questions.) Are there parts in the carb that typically fail/wear out?
Lastly, what is a reliable and quality source for parts outside of the dealer since he needs new rear pads and rotor and both rear CV axles.
Thank you for your time here.
