hi i have a toro personal pace with a techumseh engine and it had trouble starting cold took a few pulls once it ran it started first pull but i cleaned out the carb and that did fix the problem, it started right up but it idles pretty low and i adjusted the idle speed but it didnt make to much of a difference and it sounds like it looses some power when i push in the personal pace to make the rear wheels spin but i did notice that the top of the carberator bowl is alittle corroded and the gasket for the bowl is cracked a little. could this be the problem on why its idilng low and not running right?
