I have a Qlink frontrunner 500. It was sitting through an unusual amout of rain. When I tried to start it, it would not. So, I changed the battery. It would turn over, but not start. I took off the line going to the fuel pump and it was dry. I changed the fuel pump and it started, but was running really rough. I ran the gas low and put in some heet, thinking that the gas had water in it. I also connected the fuel line to a can of sea foam. It started again, but ran rough. I went in to change the plug and notice the nipple broken off of what looks like the oil and water separater and the top hose was dangling. After a couple days of glue, I replace it, but now it wont even start. It just turns over, but will not start. Can you give any advice
