OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines Over Revving Victa 550

Hi all I have a Victa 2stroke 550 that screams it tits off. All o rings have been replaced bottom engine seal/bearing have not. Any ideas?

Have you tried another carby on it Heff?

Does it run the G4/LM carby?
If so make sure the poppet valve is set in its right position...

Well you sucked me in, I had never heard of an Over Erving mower. Apart from that, can you get to the throttle and check that it is closing at low setting?

If it is a full crank engine a dodgy decompressor can cause over revving as well as a crank case air leak or blocked jet.
If it's a power torque it could be the top starter oring which is common does the engine respond to throttle at all ? Or does it just scream the same all the time

Perhaps the rarest of all Victas.

I will move this topic to the correct form and re-name it shortly.
