FUEL CONTAMINATION
Posted: 15 Mar 2014, 14:26
Storage of bike and fuel systems over the winter (what winter you might add) has always been an interesting subject, with premix and without.
Do you:
1. Drain fuel tanks and carb
2. Keep tanks and carb full
Well for 4 months I kept all the ARs and RD drained with fuel in tanks, no problems whatsoever.
The little IT 175 on premix was also drained, but would not start with new fuel in it, the carb was full of green slime on everything, the jets were all blocked, so what happened, why all the gunge in the carb, and why all green.
It would have been impossible to clean by hand, nothing would get the slime off the inside of the float bowl or clean the jets.
The only good thing is I bought an ultrasonic cleaner with heater last year and have never used it, WOW, it was cranked up to 65 degrees C and cleaning solution added, the carb was stripped and immersed.
After 15 minutes everything looked like new, and it now runs great, glad I bought one.
