OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Victa Two Stroke Engines victa commercial 1980

I am rebuilding one of these is there any tips.. It was siezed but moves freely now, have pulled apart and cleaned, i really want to get those back wheels turning.

which model commercial mate? like a 505 s/p?

where can i check that. numbers i have are. EN 71935A. thanks for the help

if you have a look at the post headed ' can anyone put a name on this mower ' , that mower is a 505 s/p , is that the same as yours? the number you have sounds like a parts # for an engine part.

Its a victa 550 full crank series 80 mk II.

Yup, so that makes it an early 1980's model. The last few series of the full-crankshaft 160cc engine, with electronic ignition.

These were made from about 1980 to 1984, when the PowerTorque half-crank engine replaced the full-crank one.

That alloy deck looks like it's a 'Pro' series to me, but hopefully someone with greater late model Victa familiarity will chime in.

Cheers for the input mate. is it worth anything?

yep, 550 pro series, ( all these where sold as pro series) and are a great slashing mower, they came as push or self propelled. I have had two for years and they are well worth saving. The only real difference to the rest of the Victa range is they run a longer lower crank than normal, yours has a very interesting tread pattern on the rear wheels.
As for what their worth........the last one i got was from the nature strip

thanks for the feedback, thats where i found mine. i have the motor back in the lounge room with my toolbox and some gasket goo and some gasket,type, paper. I really appreciate the input mate, couldnt get the thing going, obvious gasket fail so i will replace the head gasket. i got a new one going to stop getting angry. sorry new hobby

lets know how you go getting it going, i wouldn't recomend gasket goo for head and base gaskets, get the right ones if you can, makes life much easier.

just got given this for $20 keystart commando 2. am thinking of just changing the engine with one i know works?? i think where you turn the key is stuffed.
Any ideas?? thanks

Yep, there's a lot missing there. The pull starter assembly, cowl, carby, intake snorkel and most importantly the top half of the electric starter motor. It's definitely an eaasier option to replace with a known working motor than trying to get all the bits you need for that one.

I have all the other parts will put it together this afternoon. will let you know how i get on

running just need battery, woohoo

i am back to working on my series 80 rebuilt motor, has compression, dont know how the carby hooks up, has no spark, think i forgot a washer between the starter and the motor. uuummmm

one of the reasons for no spark could be the coil wire needs to go to the plug ( in front of the head) ,and not the plug you've got in the decomp hole ( the one in the top)....... two wires in the back of carb are kill switch, if their touching it wont spark, and there's no washer between the starter and motor. but they are tricky to put on if you've had it off.

cheers for the input, yes i will put it back properly , the starter? how tricky??

have you had it off??

yes

hmmm, i;m not sure how to describe the method, it goes on the reverse of taking it off, if you noticed how it was and put it back the same it should be ok, if it;s not working right then it may need explaining.

is there a washer between the plastic and the motor, where the centre bolt of the starter goes??

from memory no, you need to line up the plate on the back and put the two top screws through, fit it to the motor , making sure the spring is in the right place, then screw in the center bolt, then the top two.

i will take a pic

squizzy thanks for the help i got destracted by other(easyer to fix)mowers. i hope i have learned from the experience. got a tecumseh going today.
have to turn on my victa brain. that starter has got me.
when pulled it wears the plastic
i do have all the other parts, plus more.
