Work on the JAP 2A
As promised I am posting some pics of the J. A. Prestwich 2A which is now starting to come together.
It was bought in this condition with half an HT lead, a holed exhaust, and paint that had been applied with a yard brush.
The engine was not siezed but due to the lack of an HT lead it was difficult to assess the condition. Once the HT lead was repaired it gives off a nice big fat spark so, touch wood, she should be a runner as there is plenty of compression and some nice exhaust pops when turned over. The starting pulley was also chewed up where someone had used a chisel to try to remove the flywheel, presumably to fix the HT lead. As they had failed miserably, the pulley has been replaced. All of the tinware has been removed and taken back to bare metal with a wire brush in the drill. Red Oxide was brush painted on and then flatted and sprayed with..... Yes, I decided to keep the red colour as most of my other engines are green so it makes it stand out a little bit.
Here's the tank hanging up to dry
The fan shroud now painted
The tank brackets (straps still in primer as these will be black)
I have replaced the exhaust and cleaned up the block. Just the air filter to sort out before putting everything back together.

Re: Work on the JAP 2A
Looking good, I must get my 2a finished, I managed to pick up a set of rings for it last year and the vavles need doing as it is very low in compression. In fact the rings would have been done if I could of found my socket, I couldn't so started to do something else

Re: Work on the JAP 2A
That's always the way. I might have to strip this one again yet as I haven't had it running. Luckily I have got another 2A which I use for spares.

Re: Work on the JAP 2A
Think I'll have to take the carb off next week and give it a good clean. Probably end up making new gaskets like I had to for the Briggs & Stratton

Re: Work on the JAP 2A
Hope you get it sorted soon and it's not to big a job, keep us posted on the work you've had to do to get it up and running.

Re: Work on the JAP 2A
There a nice small engine to work on Neville not to complicated. Some of the early engines bring good money for a small engine (£75-£80) and can be picked up cheaply. Also a lot have a generator or water pump attached so your all set to show.

Re: Work on the JAP 2A
Mine's actually a 2S which is basically a 2A with a larger tank and a bigger sump designed for longer running applications. They are a nice engine to own if you can find one.....

Re: Work on the JAP 2A
Stu i am looking for something small that i can work on away from my workshop which is a few miles away.
i was looking for a villiers but this will do nicely, something i can practice getting really good paint finishing on and have a play in the evenings and weekends at home, also something i can lift onto a bench in the conservatory.
it needs to be cheap too.

Re: Work on the JAP 2A
Well it's been a day of mixed emotions today. I had a bit of spare time so I decided it was time to try and start up the JAP. I poured a bit of petrol into the tank and a drop down the plug hole for good measure. Second pull and she was away. No smoke, just running nicely except for a slight leak from the petrol tap.
All good then ??
Ah, that leak. I had sprayed the engine cover and tank with some red multi purpose paint that I had bought from Wilco's as it was a good colour match for the paint that the engine came with.
Let me advise you all now........ do not use paint that is not up to the job !!!!
The paint just peeled off under the petrol. I have had to strip the tinware and the tank off and will now have to sand it all down again and repaint it GGRRRRRR.

Re: Work on the JAP 2A
I think a lot of us has done the same thing, we should just be patient and paint a small square let it dry for a few days then give it the fuel test. Save us all a lot of grief and hard work later.
