So my toro personal pace lawnmower was running fine at the beginning of the spring and I changed the oil and spark plug, got a new air filter fresh gas and everything. Ran fine until lately it's been hard to start when it's cold and I cleaned out the carb and everything but it still has trouble I can't seem to figure it out it may be that there's something wrong with the primer bulb and it's not getting enough gas I'm not sure. Please help someone because I do a few different lawns and I need it to run right in order to keep up with everything. Oh and also I noticed the gasket for the bowl on the carb has a tear in it not sure if this could be another issue
