Thanks all for the advice, am taking it out for a spin tomorrow so will do some testing with the retarding. Ill let you know how I get on. Chillihot Boats coming out for an anti foul - whats the best product on the market?

Now confused, different people saying different things, Am I too far advanced or too far retarded?????????????????

Thanks - just to qualify the jargon backoff means retard the timing? would that be correct

Thanks all for the help yesterday on the Alternator issue - think I got there, however will need to buy a more substantial unit. Moving on to next challenge.... On my 1600cc cortina inboard I have recently upgraded the points to an electric ignition. All went well and engine runnung smoothly. However when I start the engine on the first couple of rotations, I get an explosion (sort of a squeeky hiss bang) and a puff of exhaust gas coming back through the carb. The engine then fails but starts Ok shortly afterwards and runs fine with a smooth rev curve. Again when I stop the engine I get the same explosion. Something can't be right, as it didn't do this on the mechanical points. I have checked the valve tappits and shoved plenty of redex down the carb to ensure I have no sticking. I think it could be timing issues but a bit lost. These explosions can't be doing the valves & pistons any good.... Any help from the pro's ?

Right - opened up the Acorn Unit and it was fried !! so disconnected it. Also replaced the bulb on the dash just in case and Installed the new unit. Seems to be running OK now , however, only getting 13.2V across the battery terminals when running, is this down to the Alternator only being 35 amps? Im a bit concerned still that the batteries are not charging !! Any advice?

Thanks, Just spoke to the MD of Acorn who has ginen a fet tips as the unit isnt working !! Thanks

Ok undersatnd that bit, so lets say I'm at that stage as its half hour each way to the boat! when I do this what's next?...........

Thanks all for the feedback, I have tried to post a picture of the old LRA100 but having upload problems. I have found out that I have a Kestrel 90 alternator controller and this "field" wire might be someting to do with it !! The new 101 dosnt have this and could be the problems to the light and charging (any one know if this is the case??), Can I adapt the new one to host this wire , with some soldering etc...? So not now sure on my next best steps.... Put the old knackered one back? Adapt this new one? or spend £100 on a different one? Best advice please, but for the time being would like to utilise the new one....... Thanks for your help Simon

Hi - I'm sure I'm not the first or will be the last but need some help on an alternator swap. I had and LRA 100 (old lucas) alternator on my boat engine (late 70's Cortina 1600cc), which was old and not pulling its weight. I have sourced an LRA 101 which I was told would do the job. However on the new unit there is a wire missing !!. On the old 100 unit there was a green wire which was a perminant fixture and came out of the alternator's housing, this connected onto a connector and disappeared into the wiring loom (not sure if it was an earth or someting to do with the charging light). The other spade connectors seemed to be the same (2 wide and 1 narrow). I have now installed the 101 and althought he engine starts I'm not convinced it is performing. The problems I am experiencing are; - The charge light on the dash is now constantly out. - I have not connected the green wire as there wasn't one! - I have a test device to put across the battery and the charge is not higher than when the engine is not running. Can anyone off up any help? Thanks
