hot start problem...

[whitewolf]

Is there such a thing on the M series?

My taimar cranks over brilliant from cold, but drive it anywhere then switch off and back on while warm still and it'll turn one revolution...stop for about half a second then turn and fire up.


I dont recall having the problem last year but it appears to be here now..

The earth lead used to be dodgy so battered it with a hammer and soldiered the ends.



I have though (thinkin about it) re routed the starter wire from the battery to the bulk head end of the stsrter and then goes along the engine to its terminals, last year it went from the battery to infront on the exhaust manifold then between the manifold and block to the starter connections.



Self inflicted? Or time for a new lead regardless?

I dont think it's the same thing but last year I would sometimes have issues with my starter motor getting very hot, throwing in and then just clicking due to it sitting right beside the exhaust. Sorted by having it reconditioned and attaching a heat shield.

Hi Mick, it could be a timing problem, if it is a little too far advanced, it will cause the engine to lock up against the compression for a moment and then fire up. you can tell as you can feel the kick when it does.

I like Dryden's thinking! You might want to review this thread. Could be that the PVS isn't working meaning that the dizzy stays advanced even when hot. You could try just disconnecting the vacuum pipe from the dizzy when hot to see if the problem goes away.

Ah forgot to mention, since last year and this, I've fitted electronic ignition and changed timing.


Guess its time to check bits :-)


Cheers so far

Mick,

What electronic ignition have you fitted, and whats your timing at (pre-ignition) ?

Powerspark and 14' btdc. (I think)

Its using the timing mark on the casing and tooth on pulley.

If you think the earth lead is iffy, change it..........i've got two, one to the engine/starter-motor and another to the chassis. It doesn't sound carb (fuel or air) related (vapour lock). Whats the condition of the coil, condition of the vacuum plumbing ?

[whitewolf]

I have an earth lead from the back of the engine/bell housing to the chassis and ah yes I see your point, one from the chassis to battery.

Definatly worth a change for a try.

Coil is brand spanker, only month and a half old. Fitted same time as the EI.


Weirdly tonight I did my normal, got home, turned off engine, open gates and garage, restart car (didn't do it as much as normal) and car away.

Keep in mind the elec ignition is a capacitor (do I sound as Doc in Back to the Future, or what !) and need a few seconds to 'load', cold and hot, granted.......

[whitewolf]

Hmmm I didn't realise that as Such.


Regardless she still fires up so possibly me worrying about not a lot.
