Here We Go Again! Tarpen Take 2

as for the piston situation ive not read all the postings but get an idea
the steepest angled side of the crown usually goes to the sparkplug side on a 2 stroker

Funny that, I would have said the spark plug goes on the sloping side, not the shelf side (if you see what I mean), but it's different on different engines, which is why I said it's in the wrong place on the Stuart Turner. It's more to do with the transfer & exhaust ports with a deflector top piston, as they are shaped so that the action of the petrol/air mixture coming in drives out all the exhaust gasses through the proper port.
But you know all this anyway, & if you ever make the mistake of putting one in the wrong way round then you'll soon know what it feels like, just hope nobody's there to see it!

Matt everyone makes a mistake now and again, so what, as long as no ones killed there's no problem thing is you sorted it even tho it's left you red faced and you didn't take the stance of saying no it's right and trying to get the engine running as some others would do and not own up to it.

Cheers, Stu.

I've found the phone number I was looking for, so my next project might be in the pipeline. Just need the bloke to pick up his voicemail messages now. That's if he's still got the engine I was after....

Fingers crossed for you Nuts that you get what your looking for.

Just had a call back from the bloke this morning, the engine is still there, can pick it up this weekend or next, so just need to sort the transport out now & a new thread will be started soon.
