A while back i began having trouble starting my 450. I suspected it was the valves as the hours
were getting up since rebuild.
So i reshimmed them , only one intake valve was slightly out of spec.
I also cleaned the carb whilst i had it apart.
I put it all back together and seems even harder to start.
The only way i can start it now is by push starting it, and then if it fires keeping
the throttle on etc, even then it dies quickly, but at least it does start.
I did put new fuel in and made sure the airfilter wasn't over oiled.
I suspect the carburetor still isn't right?
Would that plate that goes onto the slide inside the carburetor possibly
cause these sort of issues if i mistakenly got it upside down?
Also i noticed the bowl leaking a bit which it didn't used to so maybe that
Appreciate any ideas.
