Foolish thing, but I tried to cross a creek that was too deep for the quad. Tried to keep engine going, but it stalled with water. Thankfully, I pulled plug, dried it, pulled started and repeated process about 20 times. Finally, it restarted and ran fine. No water in dip stick. Got back home at end of day, and now I need to make sure to take care of everything.
Of course, I'm changing oil and filter.
What else can you recommend I do?
Belt is not slipping at all, everything seems fine.
I did find the reason it stalled.
The rubber air tube between the filter and carb has big split in it. The air filter was dry, which led me to look further, and sure enough, I found the split which must have drawn water in.
Need to get that fixed too.
Thanks everyone, first time back here in a while.
