I have a problem with my Holden 186 powered 2A (I know the best fix would be to get rid of the Holden all together....but that's a job for another time) It starts fine from cold however when it's hot it is a real curse to start, when it's hot it turns over very slowly to almost not at all (sounds like a almost flat battery, but it has a new battery) leave it 15 min and it fires up fine again, I have replaced things like the coil and it has a new alternator. It has had this problem for some time now and I want to solve it, any ideas would be great

Hi Medic,

do you have a heater hose pipe going from the water pump to the inlet manifold and back. on my series one which has a 186 in it coolant flows through the inlet manifold and back.

im taking a guess here, when the engine is turned off after running, it builds up a little more heat and can affect fuel in the bowl in the carby, fuel lines and the filter causing a "Vapor Lock" interupting fuel flow to the engine when trying to restart.

if this is the case, might have to put a heat shield between the carby and the manifold and insulation around fuel lines, etc.

Have you got any problems with the Cooling system?

regards,

Chris

The slow turning suggests an electrical problem. The most likely is a bad earth between chassis and engine, but it could be the starter itself, with a problem exacerbated by being warm.

I kind of thought it might be electrical, ie huge voltage drop when hot. I was hoping that the all seeing, all knowing out there would be able to steer me in the right direction

Is the battery under the seat? Does the exhaust run under the battery? I had a 2A six with the muffler under the battery, and it did wonders for battery life. Have you fully charged the battery?

Starter motor poling. Needs new bushes. They really are cheap and easy to fit, just soak them in oil for a few hours before fitting them. By all means look around for more problems like loose connections but if the starter also makes a "whirring" noise when operating the its the bushes. Metal gets hot, armature expands. Fix it quick before you burn it out.

Also, what is your static timing advance? Too much static advance will cause the motor to turn in short jerks as it fires before TDC. Retard slightly and try again.

My series 3 was hard to start when we first got it, turned out that it had the holden and land rover solenoids in paralel, so both had to open to turn her over. teh holden one was on the starter motor under the extractors, and the landie on visible in the engine bay. put them all on one side of the landie one and she worked fine!

You know, strictly speaking, throttling the staff is my job

Has it always been like this? this can also be a sign of tight rings. Unlikely if the engine has not been freshly re-built.

My guess is that it is the starter, in need of Brushes and Bushes, it is probably a Bosch unit, but could be a Lucas as they were used on various years of the Red Motor,also the Chassis/Block earth strap could be loose or missing,goes between the top and bottom nuts on the left hand side engine mount, usually left off on engine changes or by slack mechanics,it is essential for good current flow between chassis and engine and affects the generator/alternator to battery charging and also the instruments readings, remembering that all and every piece of electrical equipt and light has it's own earth, it can be the root of a lot of problems.

cheers
