Hey Guys,
I have always had an issue of slight over oil consumption. Just put it down to the OMC guzzler. No issues with it running to WOT and starts fine. I just cant sit and idle for extended periods, she likes to run mid-flat out or not on at all.
After running for a couple of hours she smokes on after sitting off for 10min, even with engine being warm. It bugs me because the plugs get glazed/oiled up from it. They aren't dripping but would be if I idled for a while.
I got back home to flush and the Port #6 was the oiliest. I had erratic revs from 900-1100, so fouled plug I guess.
I use QL78, but I got to clean them after each run almost.
To find this issue I have over the last year totally pulled the fuel system down.
Replaced Carbs & Bowls
Replaced fuel side parts of OMS (It smoked before I did this).
All new fuel lines and primer.
New fuel bracket screen filter and orings.
New fuel separator.
Inspected the vapour pump.
New oil tank vent cap.
I have not pulled the vapour separator float down.
After completing all the above there are no leaks. The primer bulb stays hard over 24hrs, so cant be anything prior to the VRO....
I would say I'm consuming alot more than the oil specs. Tank is 6.8Lts - For 40litres of fuel it would use close 1.8ltrs (Going by that oil tank photo, it was full on on that run). Assume the oil is consuming double what it should be.
I would appreciate what I should be doing next. It's not a show stopper issue, just annoying.
I'm getting pissed off with this OMS if it's that.
My neighbors hate me starting it in the street.
