Hi, i hope someone can give me some advice here. I have a Toro 325d. the last 10-15 times i used it it was very hard to start-had to crank and crank. last time it would not start at all. i have replaced both fuel filters, fuel pump is pumping, electrical seems ok(fuel cut out works), fuel injectors have been checked(i was told they are a little weak but should be ok), i had fuel injector pump rebuilt, i was told compression was"pretty good in 2 cyl. and a little weak in 1"..... i was told the only thing they could do was to replace engine because this engine couldnt really be rebuilt or wasnt worth the trouble. other than this engine problem it is still a good mower.......what do you think?
