Update — just checked pump flow rate as Charles suggested. I have a brand new electronic pump from MGB Hive and am getting only 0.6 of a pint in 30 seconds from copper pipe end in engine compartment plus flow seems very aerated. This equates to about 9 gallons an hour and am wondering if this provid...

Hi Charles, Thanks for suggestions. I have replaced fuel filter and fuel pump, but not sure fuel comes thru at speed you quoted. Fuel line comes out of side of tank where I believe gauge is also placed. Is there any in tank filter that could become clogged? Have checked carb to carb fuel line and fu...

OK — just about reached the end of my tether with my car. Thought I had it running reasonably well so would take it for a test drive today. Started the car, it popped and banged and just died refusing point blank to start again! It is as if it is not fuelling properly, if at all ,but I ‘ve had carbs...

Thanks Paul, at least I can now set off on my first drive with the switch in the right position!

Cheers, David.

My early rubber bumper roadster has the column mounted overdrive switch but my handbook is for the slightly later model with switch on gearknob —- so simple question — to switch overdrive on do I push lever down or up? Sounds silly I know but I don’t know which is the off position! Many thanks, David.

Hi Vic, Haven’t touched the internals of the choke devices. I have changed the connecting spindle levers location though. Initially these were resting in the large upper square hole in each choke quadrant, however I moved them into the lower smaller square hole as this gives a more efficient mechani...

Hi Charles,
Yes, new points, condenser, rotor, cap, leads and plugs.
Carbs cleaned, float valves replaced and new jets in place.
Tappet clearances checked.
Cheers, David

That sounds quite reassuring Charles! I have had the car for 9 months, previous owner delivered it to me and I’ve never driven it. Planning to take it out next week, if it ever stops raining, and will check plug condition before and after run.
Thanks David.

Hi Vic, Thanks for your response and I see where you are coming from with the choke suggestion, I will check to make sure cable fully closes mechanism. The reason I’m confused is that surely the choke in each of the 2 carbs services 2 cylinders each, but I am only getting excessive carbon on 1 cylin...

Hoping to pick your brains again chaps! I have just succeeded in getting my early rubber bumper car up and running. Have HIF carbs, 45 distributor with points (for the moment), silicon leads and NGK BP6ES plugs. Static timed at about 12 degs BTDC. Dry compression tested at 140-150 for each cylinder....
