Geoff the zenith web site lists a c1407 or c1406 24t2 for the jap 5
But the listing says a c1247
Any idea which kit it needs?
Not much difference
Choke 13 main 62 air 175

Geoff did the later japs have z24t2
I’m told the flange is bigger but would later manifold fit a jap 5?
What jetting would it need?

Thank you Geoff

Is it it easy to convert to zenith, same fitting, linkage etc
What main jet would I need?

[vhgmcbuddy]

Any decent machine shop will make them for you.

One last question will I need to add a lead substitute in the Petrol as this engine probably designed around leaded ?

[vhgmcbuddy]

Okay cheers. Looking it up found engine range (80200 to 81299). Also can be used as powered wheelbarrow if you find the parts

Thanks for replying. Not sure how to download pics. I did a bit of research. Alloy head with eight bolts. Models 17/19/22 ? Also logo fits between 1976 to 1985. Rotavator has not been running since late 1980s I think ? One interesting thing the fuel tank, pick up and carb are in excellent condition. Not like some old motorbike tanks I’ve seen. Might be something to do with leaded petrol !

Thanks Dorigny, your help is greatly appreciated. The chap I bought it from said it had a BSA engine in it when he first had it, I think he was probably mistaken.

Thanks Charlie
How do I go about putting an advert in the Cultivator

[vhgmcbuddy]

Me again with my Dynamow questions,

I appreciate you guys taking the time to reply to these, as im guessing they dont really fall into the vintage category.

From your last replys, im assumed that these where pretty rare, however ive seen at least 1 pop up on ebay every 3 months or so and a couple elsewhere.

Do any of youy own these machines, or know of anyone else that does? Just trying to work out how rare / common these things are. From the looks of it the body panels are the hard to come by part.

Or anyone know of a more fitting website i could look at to satisfy my Dynamow curiousity?

[vhgmcbuddy]

Thank you for the information Charlie. Regards, Paul.
