Drew 0 #1 Posted March 4, 2014 Hello, I have a weird one. I trailered a Raider 10 with a K241S and transported for 4 hours on a trailer on highway. It did get some salt and spray on her, but hardly anything on the engine itself. When I returned and started it up, it runs REALLY rough. It doesn't stall, blows black smoke, and will throttle up, but it struggles with loud pops. I pulled the spark plug and it's oil covered, and I can see oil on the valves. Anyone ever experience this? I can't imagine it's coming through the piston just from a trailer ride. Maybe through the intake? Any recommended steps to rectify? Thanks! Share this post Link to post Share on other sites
cleat 5,777 #2 Posted March 4, 2014 Check the oil level. You may have dumped a lot of gas into the oil if the float got bounced around too much. Just a thought. Share this post Link to post Share on other sites
Kelly 1,029 #3 Posted March 4, 2014 I agree check oil level, and smell it, only 2 ways oil can get to the head past the piston or the valves. Share this post Link to post Share on other sites
Anglo Traction 761 #4 Posted March 4, 2014 If you haven't already solved the problem, try checking the Air Filter Element. It may have got wet and is creating an intake blockage. Could explain all the symptoms it has, and that I was ok prior to the Trailer Ride. Share this post Link to post Share on other sites
Drew 0 #5 Posted March 4, 2014 Guys, Thank you very much for your help. I'm almost embarrassed to post the resolution, but I found the choke control was moving the sheathing and not the cable. The choke, basically, was stuck on and I didn't notice until checking the air filter and carb for blockage. . Still doesn't explain the oil soaked plug, but she fired up this morning purring. Oil was full, but smelling it is a good idea. Are you suggesting the oil level might be overfilled now if gas leaked in? Share this post Link to post Share on other sites

It wasn't oil, it was suet and gas mix 1 Share this post Link to post Share on other sites
