I'm not sure Rhys. I  haven't put a micrometer on it yet but I will when I get home from work. I'll also do a comparison with the other engine That's in the kart.

Just curious Jim. As you probably know all the TAV units are imperial. At least getting a 19 mm shaft to 3/4 is not as difficult as getting a 25mm to 1 inch :)

Measured the output shaft on the 38 quid engine and it was 19.00mm so an imperial tav should fit.

Standard practice is to bolt the engine down and dress it down with emery tape while you run the engine until you get the fit I was told. Theoretically 19 mm is 0.748, I'm informed some of the TAV won't quite fit.

Just checked and the metric equivalent of 3/4 is 19.05 mm, so it should be a slightly loose fit, just needs a bit of 0.025 shim.

That's the theoretical Chris. all the ones I have had aren't quite that accurate.

Hooray, a day off work today. I put the 38 quid engine in the kart last night. The weather looks like it might be nice today so a little test could be on the cards. Please remember folks, safety is important and when testing, drive it like you stole it.

I managed a longer test yesterday and it pulled real well, Even up quite a steep hill. I need to make some adjustments to the rear dampers possibly because there is quite a bit of shake at low acceleration. Caused by a bit of bounce in the rear springs. I held the accelerater pedal at the point where it was at its worst and lost vision for a moment which made me laugh a lot. Hard acceleration gets past the shake quickly and it smooths out nicely. New choke fitted as well.

Was the TAV a straight fit on the engine Jim, or did you have to shim it?

I am using a centrifugal clutch and it fitted nice on the shaft without any shim. The metal cup is my new choke system. :)

Thanks Jim, forgot you weren’t using a TAV, no matter, the fact your clutch fits without shimming has made my decision for me. A number of the bits that come with a standard engine will be no use for my next two builds, so rather than buying one Honda Gc190, I'll buy a couple of these while they’re available.

I pulled the genuine Honda I have offered via here  (£60 with everything attached, clutch, fuel pump.., no interest) off the shelf yesterday and found yet another shaft size for genuine kart engines, 23 mm!
