I have rebuilt a number of victa 2 strokes however I have one that is giving me trouble. Its a standard power torque engine (The new style where the cooling fins are spaced further apart).
Upon getting the mower the guy said it just stopped and I didn�t get much more information at the time.
I completed the following:
Cleaned the carb and added all new o rings (inc manifold o rings)
Replaced the crankcase o ring
Took the head off and removed the piston and rings. Gave them a good clean and re-installed everything as it looked good. Included a new head gasket.
Re-gapped the magneto and checked for spark which was reasonable.
Went to start the mower and NO go.
I re-checked the carb and its was all good. Thought it might be a blocked exhaust. I replaced the exhaust and the engine started however it just wont rev up.
I changed the large carby spring to a firmer unit to try and increase the revs but no go.
Subsequently checked the exhaust port and it was all good.
Checked the carby float (no leaks) . The jet has been cleaned thoroughly. I must be missing something����������
Can a leaking lower crankcase seal cause these problems?
