  1. Typical of my luck... Out this afternoon in the GT6 and I had a blowout on the nearside rear. Luckily I had checked the spare's pressure this very day and fitted it in no time but I have decided to take this as a chance to replace all of the tyres with new as those fitted are getting on a bit. Which brand of 155/80 R13 would anyone recommend?

    Goes back in quite easily, dashpot between your hands pushing the washer while rotating the Allen key.

    How many hands are required Doug 😉? The washer and consequently the needle seem to be rather stiff to move so they may be against the thread so a simple question is - RH or LH thread?

     

  3. I have been stripping a spare front Stromberg 150CDSE and noticed that the Delrin washer on the needle is about one and a half millimetres lower than the air piston. The rear 150CDSE had its Delrin level with the bottom of the air piston. Based on one of uncle Pete's posts a while back, I inserted an Allen key to retract the needle such that the Delrin washer is level with the bottom of the air piston. The key engaged nicely but rotating it in either direction failed to move the needle up or down. has anyone any ideas why this should be? I had removed the needle locking grub screw although Haynes says that shouldn't be necessary.

  4. I had some similar problems with one carb flooding and it was down to the float needle being jammed open by  Uncle Pete's favourite "little black slivers". The car would start but ran like a three leg dog. I have since changed all of the fuel lines for an ethanol resistant brand (e.g. Gates Barricade) and added an in-line fuel filter - the glass type - between the pump and the carb inlet which means that I can easily monitor what is going to the carbs. Since fitting the replacement fuel lines, that filter has stayed clear and there have been no further instances of carb flood.

    tie it round the front Xmember  under the engine

    Just make sure that you don't have a brake pipe alongside this bracket which you end up wrapping the tow line round and damaging.

  6. Interesting thread - engine gets hot and carbs malfunction (spitting back). Is there too much heat from the exhaust manifold adversely affecting the carbs? Where do the carbs get their cold air from? Cold air has to be essential in being both dense as required for effective combustion and cold for helping to cool the carbs. I had an exhaust leak on a Kawasaki 4 cylinder bike that directed hot gasses straight at the float chamber of number 4 carb. It caused the engine to run very rough. Took the exhaust apart, refitted it with some exhaust paste on the joints and the problem was cured.

  7. A starter motor when not turning over is effectively a short circuit - super copper conductors connected between +ve and -ve. Only when it starts to rotate does it develop a 'back emf' which is the resistance that prevents it from cooking. If the motor can't turn, it will cook! I would advocate removing the starter motor and making sure that it spins over OK when disconnected from the starter ring. That's a good starting point in your diagnosis. If it does, then your next step is to make sure that the engine turns over freely. A newly refurbished 'tight' engine shouldn't appear that way to a starter motor that is designed to turn it over. If you have any doubts about your starter motor. get it seen to by ROTATING ELECTRICS of Birmingham. These guys are brilliant and relatively cheap. https://rotating-electrics.co.uk/ 

    High Torque starter motors are good but a functional standard motor should be just as effective at turning over your engine. How many people have bought a High Torque motor believing it will cure all of their starting blues only to discover that it hasn't made any difference as the fault lies elsewhere?

  8. Welcome to the madhouse! I'm just down the road on the east side of Swindon. If you fancy showing your car, some of us in the North Wilts branch will be exhibiting at the Swindon And Cricklade Railway's event which is listed in the events forum. Be good to see you there as it's only thirty miles from Didcot..
