Very nice, you look like a professional technical trainer. But let me just make a suggestion, use the gauge perpendicularly (90 degrees) with the piston for better accuracy. I have a doubt, isn’t more accurate to time the valve opening time with the engine head in place and measure directly in the top of the valve ? I think it’s more accurate because you are seeing the result of all the gaps in the mechanical elements from the camshaft to the valve spring. Valve gap influence valve opening time…… What do you think? I’m subscribing this channel just for the quality of this video, thanks 🙏

Great video. Can I ask why you are using a single chain rather than a duplex? I thought chain stretch would be more likely in a high revving race engine?
@HREIRL

Hi Andy thanks so much, Ya we use these single row chains because they are specifically designed to handle the forces of a race engine. they are very light and take a lot of pressure off the Valve train which is why we went that way :)

Another great video. I plan on rebuilding my engine later in the year. Can you recommend what spec torque wrenches I should buy. I've already got one that goes to 150ft/lb. It's only a cheap one. Would you recommend buying decent torque wrenches or even electronic ones. Many thanks Neil

Hi Neil, I use Norbar Torque wrenches I have 3 to cover all bases on the mini. 2-20NM 15-80NM and then the big gun 80-250NM. You could get away with a more universal one say 20-150NM sykes pickavent make a super accurate wrench at a fraction of the cost of the Norbar wrench’s I use,which would work perfect for some who is only building a few engines thanks for stopping buy keep us updated on your progress 👍

Great videos and thanks for the detailed info. Quick one regarding the crank end float. You said you run 0.05 - 0.07 mm which is 2 to 3 thou. In the video you set it at 0.05 mm (2 thou). Cole over at Classic Mini DIY built his bad wolf supercharged mini with 2 thou clearance which is in line with the Haynes manual spec but he said that it was too tight, the Haynes manual was wrong and that 5 - 7 thou was what it should be set to. That would be 0.127 - 0.178 mm. What are thoughts on this? I actually found your channel through Cole’s channel as you’re doing a Q&A with him shortly. Really looking forward to that. Maybe you can discuss crank end float. I’m building a 1275 A+ myself soon so anxious to get a better understanding of what correct end float should be. Thanks again
@HREIRL

Hi Andrew, so basically the short answer to this is. The crankshafts in my race engines are ground and balanced to a very tight tolerance. Meaning when the crank spins 360 across the thrust face there is no run out. in this situation I can get away with 2-3 thou. A standard ish crank like Cole might have used is more likely to have 2-3 thou run out across the cheeks of the thrust faces. which means it can tighten when rotated or when the clutch is depressed. remind me the weekend in chat and Ill try explain a bit more 👍

So how did you move the cam timing? Jumping a tooth would be too much. I did not see an adjustment on the sprocket. On the TR3 engine they had 2 sets of bolt holes and you could flip the sprocket over giving you a range of adjustment. Off set Key?

I’m slightly surprised that you are using a simplex timing chain. Both the Cooper S and 1275 GT engines in my day always had duplex sprockets and chains as the simplex chains used to stretch, with the accompanying rattle and presumable inaccurate cam timing. There must be a reason for your choice??

It’s a swift Tune Simplex FULLY adjustable Timing chain Kit there George there is multiple key ways in the drive sprocket all 1 and 1.5 degrees apart so by simply taking off the gear and repositioning it in a different slot advances or retards the cam. 👍 no requirement for tensioner in this kit the chains are changed every 20 hours
