2001 yamaha 150 two stroke carb"FOULING OUT PLUG"

[jeffstantz]

Was wondering if oil injection can put to much oil in and foul out plugs? I'm having fuel problems but in the middle of fixing that problem just wanted to know if oil injection can cause problem..I fouled out plugs after 3 miles or about 20 minutes of idle and 2 minutes of running...Won't idle and won't go about 3300 rpms at WOT..

It can if the oil pump puts out too much oil. Check your link arm on the oil pump. Is it attached to the carb linkage? If it is, it is not your oil injection system, the problem lies elsewhere. Yamaha oil injection is solid and I have never seen one that over oils if it is connected and synched correctly.
