Mr.Dodd you have really opened my eyes intact I now realise that I was blindfolded walking around in the dark. I thought that I could tune an engine until I watched your videos and how wrong could I of been I have followed your advice on every little detail and wow what a difference I'm still possibly not spot on but in the ball park thanks to you , your videos are educational and inspirational please please keep making them

Great information Always enjoy seeing what you know and can do Just wish I was near you and was able to afford you to look at mine Your knowledge is amazing Since I became poorly I am these days limited to what I can do, but your videos have inspired me to have a go at servicing and cleaning carbs but definitely not to your standards as I’m no engineer It’s your knowledge that has inspired me to try my hand at cleaning and service twin carbs And I’m getting better at them My kindest Regards Simon

Good stuff I'm picking my engine up from the machine shop tomorrow, you've given me plenty of food for thought!

What ARF gauge should I use? Is the vmaxscart one any good ?

What sort of AFR are we talking to see bore wash to this extent? I’m assuming it’s not just a little bit rich but right down into single figure AFR? (Ie at least 50 percent more fuel than there should be not just ten percent for example)

Pretty much. From a well known 4G63 engine builder - you need to be running less than 10:1 for bore wash to be a factor. However! If it's a new hone and rings, running very rich will glaze it within minutes. A profilometer will show this.

That’s likely well into the 10’s but the point is any excess fuel is too much for running in. The point is what happens if you set the idle screw to make the engine drive nicely, it ends up being far too rich at idle and part throttle speeds. Bore wash quickly follows.

Certainly a good reason to have an AFR gauge handy when running in.

Hi, I apologize for the off-topic question, but I'm curious about how long the valve seat cutters you use last before they need to be replaced. I subscribed to your channel after watching that particular video. Thank you!

Interesting. For 'standard' use though, wouldn't a set of rings and a re-hone return a serviceable engine?

No, how can it, if the bore is honed to clean it up it’s too big for the original piston that runs in it.

@@ACDodd Well.. I guess the question is 'when can you simply change the rings'? I get that that may not lead to the absolute maximum performance, but from a pragmatic point of view, what's the tolerance?

@@gsdavies100 if your piston to bore clearance is less that 0.0035” and the ring lands had less than 0.004” side groove it will work, but don’t expect top power.

What's the difference between bore washing and bore glazing please?
@ACDodd

Same, although the term bore washing leads to glazing, the term bore wash simply describes how this glazing has happened.
