I had half an hour spare, so just had a quick look.
I unplugged the maf....and when it,did finally start, it won't idle and just cuts out.
Unplugged the lambda, and still difficult to start, and no real change.
I disconnected the fuel pipe to the fuel rail, and there is only fuel when the engine is cranking. On my 145 with the CF2 engine, the rail is primed when the ignition is turned on....is the CF1 different?
I checked the breathers from the rocker cover, and one to the throttle body is full of gunk....I stuck a screwdriver down it and got some of it out, but will take it off and clean it out when I get time.
And I think that there is a slight leak somewhere in the intake....it sounds like its somewhere on the throttlebody. If I virtually just touch the throttle, and there's a slight whistling sound...any more throttle and it disappears.
I also unplugged and replugged in any other plug I could see.
Anyway, I took it for another drive....started first time, and plenty of power again....
