Hey guys I have a 2000 evinrude ram ficht 150.....I know I know sell it and buy a different motor lol but I had some one telling me to run xd-100 Oil and a carbon blocker in my gas. I understand the oil but I'm not sure on the carbon blocker. I'm guessing it's different from a carbon guard which is a flushing system. Is the carbon blocker something I run in everytank, or only a few tanks, or is it the same as a carbon guard? If so what brand do I use? Any help would be appriciated.
A good TCW3 is paramount with today's fuels. They are not all the same. Cheap oil's have less ashless dispursments in them. Stick with the OEM names or Penzoil premium plus synthetic blend. I use the latter in my opti.
Carbon reducing additives are recomennded on a regular basis. In your case - of having excessive carbon buildup, I'd add a bottle of quick Silver "Quick Kleen" every other full tank of usage. OMC has "Carbon Guard" and Yamaha has it too. It is intended to clean off the carbon from your piston rings,-plugs, compression chambers (cylinder heads), exhaust ports, and piston domes. Exce3ssive carbon on your piston domes, will bleed over edges and get in to your ring grooves causing them to stick, loose compression and ultimately cause a major failure. I've seen many failures from running cheap oil.
Stock motors are programmed to run rich for warranty protection. So, carbon build up is an issue. Its the nature of the beast with 2 styroke motors. Your excessive fouling and carbon issues should not be. I'd contact an OMC Service tech and ask about a hotter running spark plug for your Ficht. One step up in temp range. You may also have another problem in your ignition or fuel curve programming. It could just need a good "sync and link" to adjust your throttle advance etc. You should do a good inspection of your cylinders with a bore cam (Android Camera), wal Mart, $25.
