Over the last two years I have used only NE Gasoline treated with Marine Stabil. This is for all my outdoor equipment. 5 motorcycles (XR650, XL250, CRF 50, CRF70 and PW,50) 5 ATV's (660 Grizzly, 700 Grizzly, Kymco 90, Sportsman 90, chinese 50), Then lawn tractor, push mower weedeaters, blowers ect. Point is this year i have had to take the carb off , push mower, CRF70, Kymco 90 and XL 250. All with the same issue. Plugged Pilot jets. Now the 660 is dripping gas, no doubt that the valve is gummed up and leaking in the carb. Clearly my methods are not working. Im surprised by this because most of this stuff we get out and use fairly often. Years ago i used to use random doses of MMO and didnt have near the issues im having now. Keep in mind i didnt have all the little ATVS and motorcycles that I have now. I have lots of stuff now, MMO, Chemtool, Techron, and Seafoam. I have also read about people using small doses of two stroke oil in gas as most of it has stabilizers in it. Right now i have everything cleaned up and working great, except for the 660 dripping, and would like to start some kind of maintenance dose of something. I have read a lot about overusing strong solvents and am a little worried about it. My current plan is to do MMO with Stabil. Would like to hear your success stories with any given products. Or if you know of a good post that already exists maybe attach a link. End goal is to use something readily available in a maintenance dose to avoid taking these things apart all the time. Thanks I should add that both small CRF motorcycles were used and sat around a lot so maybe had some crud in them already.
