Hello again,
well, i have made some progress.
i started by taking the muffler off to see if it was blocked. Due to the shape of it i needed to take the carby and take off to do it (there may be an easier way but the muffler is oval shape so it was the easiest way i could see)
the muffler was clear, no blockage, i could blow straight through it, and see light through it. (i didnt try to strart it as you suggested Grumpy because as it was clear i assumed that would not be the problem.) i pulled the carby off the tank and cot it ready to clean but ran out of time.
Tonight i started again but before i started on the carby i realised my brother has an edger with a Briggs motor that runs like a dream and as luck would have it it is the same motor. So we took the carby and tank off his and raced it back to mine and fitted it. pulled and pulled and the best we got was a backfire with some flames blowing back through the carby..
so i have drawn the conclusion that it is not a carby/fuel problem.
that leaves me with Tezza98 suggestion that it could be a blocked valve.
With Tezza's suggestion in the back of my mind, when we took that carby back off, we slowly turned it over by hand and looked into the ports to check if the valves were moving. The intake valve seemed to be rising and falling about 5mm which was easy to see as it had a clean spot, but the exhaust valve was alot harder to see as there was no clean spot to gauge it. it was however, moving up and down as it should so definately not jammed but not sure if it was actually moving as high as the intake (i may just be confusing the matter so disregard it if you think it is not note worthy)
anyway.. i am again looking for suggestions.. is it worth taking the head off to check the valves. ?? can you still get had gaskets for these old motors??
you help and suggestions are appreciated..
