    Valve Timing 4 Stroke

    This could be a long post but bear with me. I purchased a Chinese 4 stroke from Stirlingkit last year. Very happy with it until a grubscrew failed on the small gear on the crankshaft which jammed up on the larger gear on the cam side shaft, both gears suffered some damage. After a lot of shaky...

    Valve Seats

    Not the smartest kid on the block but have managed to build a couple of engines that actually run. I always have trouble with valves & seats and lapping them in.

    Thread Dial

    I finally decided to have another crack at single point threading following my past failures. I have an AL-320G lathe with a metric leadscrew. I changed the gears for a 1.5 pitch on a 16mm rod. I ran into problems engaging the half nut, then decided to leave it engaged and reverse the lathe...

    Engine Specs

    Hi All, regarding engine specs, is it just a matter of changing specs to a half size or are there other issues to consider.

    Minitech Engineering

    Hi Aussies, Does anybody have any problems contacting Minitech. I've phoned and e-mailed several times, no response. I got half my order with no advice on what is happening with the rest. I seem to get better service (although more expensive) from US. Kpar
