Morning All. :D
Today is my official lie-in day of the week, but as usual I am up first. :)
It gets to a point where my lower back is screaming "get off this bed NOW!"
I am carrying out a sperry-ment with the Mini. Just occasionally I get this loud "front-fire" through the intake side.
It only occurs under hard acceleration from a low speed. I don't think the timing is off because the thing performs so well generally. But, I think the sudden opening of the throttle is making the carb piston rise too quick and so it is leaning-out so much it pre-detonates. So the 20W oil has been swapped for 30W to see if a slower rise rate of the piston will help keep the mix a little bit richer. If 30W doesn't do it, then some 20/50 will be tried.
I seem to have an oil leak (yes all old style Minis leak) but this is getting a bit more severe. I think it is either the timing case seal or the crankshaft oil seal. Neither of which is fun to replace. :(

Have a great day!

Just sorted the last item in prep for my 2 x holidays this year. Insurance. Company I used last year wanted over 400 sovs for an annual policy, a massive jump from last years premium. Got quotes from Co Gompare for this year, got suitable cover for 150 sovs. Which will also cover me for next year if I take an early holiday. Or two. :cool:
