hi i have got a 1991 mini city e auto

998cc standard hs4 cu carb

i brought the car from a guy not to long ago it had been sitting up his drive for about a year and when you try and rev the car up it takes abit of time to build up to a hi rev and while im trying to rev it up it sounds like its popping not popping in they way of back fire just apopping noise from the exhaust and when you do get to a serton rev its okay

also when the car is warmed up it runs abit better Does it just need a good tune up or is there something wrong opinions please

thank you

lee

sounds like it needs a good tune. if its been sitting for that long i would start by changing the plugs points and condensor, it its got them, and then check the timing

Look to the air filter -and does the piston in the carb rise easily and fall back with a nice clunk? Also put 3 in 1 in the carb damper. Then check the vacuum advance is connected and working as it should. Suck the pipe and watch to see the dizzy baseplate move - and retract.

If the car has the same petrol in for a year the petrol can break down and not burn correctly, you could drain it off and put fresh in, or even a drop of octane booster for a better ignition burn, if things do get better you'll know it could be fuel problem, also the float chamber dries up when a car stands a long time, this causes the needle valve in the chamber to stick or partly stick,which could starve your engine, Good luck
