Are you sure it's 2.2? The
Are you sure it's 2.2? The standard fourtrak / Rocky Petrol is a Toyota 3Y 2ltr lump. I had a similare problem with one of those. I had to take the top off the carb and clean out the float chamber, as it had bits of rubish in it. These were getting pulled into the inlet to the bypass jet. So whenever you let it idle (ie the butterfly was compleatly closed) it would stall. It would run like a bag of excrament bellow about 2000 rpm, but after that would run like normal. This would sort it for a while, then it would happen again. I had to do this about 5 times over a 3 month perioud (and change / clean out the fuel fillters) befor it setteled down and kept running right.
And why 'argh' about petrol? I found the F80 I had to be almost as powerfull as the Diesel for towing, better on fuel when being thrashed continually, and better offroad (if you didn't take it near water more than a couple of feet deep).
Any veiws expresed in this thread by me are purely from my own experience, and (sometimes) falible memory. Hope my comments help, but please don't take them as gospel.
dodgy running petrol
Main things with petrol engines that make them run rough is the like of corrosion on ht leads, plugs, ignition coils/timing points, like nev said dirty fuel in carb area - use choke and carb cleaner for filters etc, sounds to me like its just dirt in the fuel mix (i.e carb)
Full of ideas but no time to do them!!
