This by far would be the worst carbon deposits iv ever seen in a small 4stroke engine. It got to the point where the engine couldnt be pulled over top dead center at all. It wasnt using oil & not blowing blue smoke. In fact the in side of the engine is very clean. This generator has had long hours with a light load.

My solar panel has done long hours with a low load and not a sign of carbon . . . and no fuel either. Or noise. Cheers, Tony

Yep - solar panel - no carbon, no noise, does job.

Solar doesnt cut it were this person works. He also runs a 3Kv diesel generator for large cool rooms.

would running kero thru the carby remove some that buildup

Hi dogbox, I dont know, it was very hard carbon as it stoped the piston from reaching TDC & was imposible to turn over that point.

what brand of petrol were you using ??? if it was Caltex or Shell i can understand it being like that

Out here in the country you buy fuel where ever you can get it. Bit different to city fuel buying.

A lot of gen operators never seem to load up the genny and think that a 3 KVA unit is required to power a light and fridge so the poor old thing just lumbers along and Wham O the genny gives up they need a load to function as the specs say they should

I recall from a previous life when I was gainfully (?) employed that we often used "dummy load" resistors or otherwise take steps to provide a load for generators especially those with turbochargers fitted (diesels in the 25 - 50 kva range)

Digressing slightly I know, Daryl, but in the last couple of days I came across some comment that these newer (sine wave) inverter type generators may have issues when operating into loads with poor power factors (0.7 or less)....have you come across this at all?

Hi Jim, Havent heard of that yet. Any idea what its suposed to do to them? Re loads on generators I tend to run flood lights when there needs to be a reasonable load.

running kero thru the carby till the engine just about stalls is suppose to cause the carbon to burn an turn to ash
