I can't remember the amount of times i un-nessarily stripped then cleaned down the carby, also cleaning the sparkplug, only to get a ever worsening hunt in eco-mode. Stripping the carby was to no avail. A drain, dry, fresh plug an' oil was all it really needed..
The design of the machines is pretty cool, the block/head splits diagionally, they are not symetric.
It was my fault carbon built up by running it only in eco-mode. The muffler filled up too. I split the crank to clean out the carbon that had packed and filled the 20mmx30mm irregular exhaust port/manifold (expansion chamber?) and valve stem. I fired the muffler
It ran like new with a new plug and single 30 grade oil, it ran whisper quiet, very very steady.
After the strip down i stepped up my prevenative maintence running it full-on for short whiles and swaping in a new plug and oil every 3-4 tanks.
Before I put a fuel filter and catch-can on it, occasionally the carby would need a sun-dry and blow if I had left it sitting, put containanated or wrong or old fuel or too much addative in it.
Mine has now done over, an astounding, 80000 Hours. I was full-time on-road for three+ yeasrs.. The first decarbon was at only 1200hours, that was my fault. The second decarbon was done at 50000Hrs using the method in previous post.
Im going to polish the ports and manifold the next decarbon to see how long i can get away running it in eco-mode...
Way way back and unlikekly to affect now and urban-hub-bub had it that the first batch if is's to Australia had packing gel inserted into thier fuel lines as an shipping requirement. Un-usually this small genny required pre-delivery at the distrubuters. Somtimes this wasn't done properly and people had hunting problems,.. That was wayyyy back, almost ten years ago. The dealership also told me to keep the oil topped right up, it helps in the sound-proofing.
Have a good run with yours, they are a good machine
