Well i'm trying to get my Mini's engine happy enough for its mot tomorrow.
I've set the idle speed at around 1100 rpm and it seems happy enough to run at that speed and will accelerate nicely from there.
The main problem is that the exhaust is very loud and making black smoke. Its puffing slightly but not totally regularly. When i put the accelerator down it will make a puff of black smoke and then settle down.
I've pushed the piston up on the carb and the revs got quicker, so i did the nut at the base of the carb up against the spring, testing it every couple of flats. I've got the nut done up fully now, and the revs still increase when i push the piston up. Problem. There's too much fuel in the mixture so could it be a problem with the air supply? I've been tuning it without the air filter on, but putting it back doenst alter anything.
I'd like to check the valve clearances and the spark plugs but i dont have a feeler gauge, i think i might have to go get one this afternoon.
As always, any thoughts appreciated, as quickly as possible!
If i cant sort it i'll have to get my MOT garage to do it... :lol:
