Hi all I have been tinkering with British sports off and on for 40 years, MGA's and B's, recently got a RHD 71 mini from the UK that has not been run for 10+ years, can't get it to idle, got spark, fuel starts but will not idle. Anyone have any ideas?
Will appreciate any help!
Thanks john

 

so you are familiar with SU carb already????

Since you've played with LBCs I don't want to bore you with the super basics ......

I mean the Mini motor is not all that different from a MGB's (B series vs A series ...... they share a lot ...... like SU carbs)

what have you tried already????

Cleaned what?

futzed with what?

PM me if you want to take it off line

 

The carb is to modern for me I know SU's, pre 60's I can work with!

SU basics shouldn't differ too much. I'm guessing you are used to an HS - side bowl - and you now see the in line bowl? Not any big difference here IMO. The needle remains the key .... but past idle . . . you are familiar with the seat of the pants richness setting? It was just mentioned in another thread here recently ... the one about setting for altitude . . .

Won't idle at ALL, or not at what you would consider a 'normal' RPM? Book says I should idle around 800 but I need to be running for about 20 minutes b4 this happens .... cold idle I need around 1200 ... and after a couple of minutes 1000

First 1/3 of the choke's pull should engage 'fast idle'; doing nothing to the mix.

Have you taken any of the carb apart? I'd at least take the 'pot' off and check for a gummed up piston spring ..... did you flush the fuel system????

Of course a good rule is never mess with the fuel system until 110% SURE the spark is solid. You have spark but is it 'good' ... I'd change the coil and nix the points for a Pertronix . . . wires, cap, rotor . . .

You've checked the timing?

 

Thanks GUYS we are cruzzzzing in the MINI!
