Hi all, I just got this mower given to me, it has a
Kirby Tecumseh 274
2 stroke engine � made in Australia.
Model: KAV 74
Spec No: E6653
Serial No: 9323 7782

I am not sure if Yeoman is the brand name of the mower or not, I have never heard of it.

It has the "Trip Release" impulse starter and it appears to have a broken main spring.

I managed to get it started by using an old rope starter cord I had, and after a couple of pulls away it went, that was after I spent 1/2 hour trying to work out where the throttle was (lol) (see pic no:3).

Any one know if it is possible to get a replacement spring for it and/or know the part number???.

The other question I have is can anyone tell me what fuel mix these take, it says on the label mix 1/3 pint of 2 stroke oil per gallon of standard petrol.

I have no idea how to convert that to 25.1, 50.1 mixture ect, I also presume that being an old motor ethanol fuel is a no no.

Thanks in advance
