My new to me but used 660 just won't run right. Any help would be much
appreciated before it has to go to the dealer for an arm and a leg per hour.
2 light scoring marks on piston but has 160 lbs compression.
It will pop on choke and then start on fast idle but will not idle unless I feather the gas. New carb kit. Same thing. After many carb adjustments, I finally got it to idle on its own, but if I blip the throttle it revs quickly up and down on its own. I assumed (with no real knowledge) there was some sort
of air leak causing this erratic revving.
Find a crack in the intake boot, so new intake boot and still the same thing.
Other notes: No problem at all to get started, but it will only start if I pop it first on choke and then start it on fast idle. Will not start in the run position. It revs high and fine but dies off like a turd. I can not pressure/vac test myself but if this is my next step, will pay to do so. Impulse line, fuel line, tank vent show no visible signs of failure.
I might have thought I jacked up the carb kit install, but it acted the same before and after the new kit.
Thanks!
