Pleased to say my copy has just dropped through the letter box. Some interesting articles and machines in this issue.

Engine date I recon is 25th May 1965 (650525 part of engine number).
Why do you think the coil needs replacing? No spark could be as simple as corrosion on the points, easily cleaned with sand paper. I have used Briggs Bits in the past for engine spares.
The Hayterette was launched in 1957 and continued in production, with various changes, for 62 years. I have a very early 2 stroke one.

Your old mower is a Hayter Hayterette. The engine can be dated using the engine number see Briggs and Startton website

Time and patience is the only way, it pays off in the end.

As I remember someone saying, every 5 minute job is only a sheared bolt away from been an all day job. I have seen the weld a nut on method of extracting tight or sheared bolts/studs used by my son with good results.

An interesting find. Looking forward to seeing the next instalment, maybe something to send to Alan for The Cultivator?

It looks like a Starky duster.

I remember talking to Ian Cox at Cox & Turner Engineering many years ago about sourcing a similar piston. One option he suggested was to find a piston for a diesel engine with the right diameter etc then machine the top to the required profile. A diesel engine piston apparently has a much thicker crown. No idea if this would work for the SIMAR engine. A more certain source would be a scrap machine.

Good news, a request placed on Facebook has come up trumps with someone who is willing to do the work.

I am fortunate, so far, not to have had to rebuild an engine to that extent.
Looking at the parts list diagram the pin will only come out one way. If it was me I would heat the piston to see if that helps.
I am not aware of anyone having spares, but there is a drawing held at MERL, drawing number 5269 MERL ref TR/DX/1607/8/5269

Sounds like con rod is broken or big end. The only way to find out is to strip the engine. If the piston is not moving that would explain why no compression.

John, you will need to contact the Museum of English Rural Life (MERL) at Reading, I only have a list of the drawings. The drawing you require is drawing number RD.310 the MERL reference is TR DX 493/1.

The only information, (taken from Brain Bell’s book 70 Years of Garden Machinery), I can find is Wrigley motor truck was invented in the early 1930’s and Geest made their motor trucks from the early 1950’s.
