Thanks Colin for your reply, The reason that I am searching for a steering rack is that the DPO welded the steering column to the rack where the two connect at...
G'day Jeff Don't you just love DPOs? Grid away the weld where the steering column is attached to the pinion of the rack, dismantle the rack assembly, and I can...
... You know I am constantly amazed at the depth of knowlege around here. I wouldn't have known that the stickers were different for each filter. In fact I'll...
After much scratching of heads over the rattle, we took the plunge and pulled the motor out again. On dropping the sump, we found the culprit.Undersize...
I used to run in new engines the old way. My latest engine was broken in with 100 miles of flat out racing. now ,no blow by through the vent in the catch tank...
Hello gents, I've always used full throttle in intermediate gears(sometimes top gear), at medium revs (varying the revs thru the middle toque range),...
I've added more pics to "Hobbit" in the gallery. He's back as a daily driver and causing much pleasure. Added some airhorns on the weekend to frighten the...
Whilst running in Hobbit, I must admit to taking things a little carefully. Nothing special, just avoiding max revs and keeping things with as little load as...
Hi all, have posted photo's of the cylinder head porting job that I have just completed. Have reduced the compression ratio to 7.9:1 by enlarging the...
no interest...just seems like a good find http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Parts-Other-makes/Electrics/auction-126086257.htm ... ...
The Queensland Sprite Clubs Annual Expo was held on the 28th of October. As usual we had a great day. The weather stayed dry, although it started off very grey...
Hi All, For those who may be interested,I have posted some photos of my new Sprite engine. I have rebuilt the engine using 1.5 roller rockers,Omega off-set...
Hi Colin, Been awhile! Very interesting pictures. Fyi, just managed to find time to install the Midget crankshaft and flywheel from you. Bored out 60 thou,...

Excellent! I'm toddling in tomorrow. Thanks for the advice. Baz. ... your existing unit and have it back to you better than new. We will repair and calibrate...
Hi All, These early BMC tachometers use a very simple and crude multivibrator circuit to run the moving coil meter in the tachometer.They use germanium...
Vizard's book devotes two pages to measuring the compression ratio - I won't set it all out here, partly because I am a lazy bastard and partly because it ...
Hi Bruce, the compression ratio is the total volume in the cylinder including the combustion chamber volume ,divided by the volume left when the piston is at...
Hi,My post was to Treaka not Bruce who covered the subject well and also mentioned the piston dish volume that must be included in the calculation. Cheers...
G'day all Garth, do not lose sight of the fact that the static compression ratio (as explained in detail by Vizard, Miles, Phillips et al) has very little...
I could go in to the zen art of compression ratio's and spridget maintenance. However I was recently asked what the compression ration was of my car... I didnt...
Treaka, you are right.It is an art.The static compression ratio has little relevance on a working engine. With static C/R,the cylinder is completely filled...
G'day Garth The short answer is: You can only calculate the compression ratio when the cylinder head is off the engine. One of the factors that go into the...
G'day all. I've driven my ex-US, '73 Midget nearly 100 miles in the last couple of weeks, and it is almost ready for registration. It drives well, and is a lot...
G'day Don, and congratulations on the progress. We will not ask how you have driven it 100 miles, before getting it registered! I can supply inertia reel seat...
