So I'm having a problem, I think it is a pressure loss problem.
Basically I notice that sometimes (not always, and not all the time) but fuel is not getting to my carb. I don't know how the pressure is being lost. At first I thought it is a leak of some sort anywhere from the exhaust to the tank. But now that I'm thinking about it, to figure this out I took the fuel line off of the carb and started to try and prime the engine and after a few pulls the fuel started spilling out.
So maybe there is a clog of some sort in my carb?
Only thing that makes me really confused is once I give a little trim (little bit more then when "nothing is wrong" and I'm starting the engine) and the engine gets going there isn't a problem for a while.
Only reason why I think it isn't just a priming problem (like I didn't prime the engine when trying to start) is the problem seems to happen while running. I'll just randomly be bashing around and the engine will die.
After walking to my buggy and trying to restart It, I feel that there is no fuel in the engine, so I usually check the tank to see if I'm out and most of the time I still have fuel, usually 1/4 or more of a 75cc tank. So I've come to the conclusion the pressure is lost some where and doesn't push the fuel through. I've also died on a few WOT. I doubt I'm running lean, but I guess this might of been that issues. I really doubt it though.
This whole problem has only happened around 3 or 4 times total but even once is enough to be a problem.
I've just replaced all my fuel lines and I have no kinks or anything.
This whole thing leads up to my main question. Can I take apart my exhaust and clean it out.
I've only ran about half a gallon through my buggy and I've been running very rich, I'm thinking it might be clogged a little bit, but I'm not sure. I don't see why I couldn't take it apart and clean it logically speaking but everything I see says "TUNED" so I wasn't sure if I could like un-tune it or something?
Anyone have anything/advice?
Thanks for reading.
