It is a little known fact that distributors should have a drop or two of oil under the rotor button every 6-12 months. To stop the little nylon clip from pulling off sometimes you need a screwdriver to hold down the mechanism. If everyone did that service they would last forever!Quote:

Do you just use a generic one?
The reason for my broken rotor button wasn't due to it being stuck on the shaft. I was doing something that I can't even remember which entailed taking the distributor cap off. I later tried starting it but had forgotten to refit the cap. The rotor hit the cap and shattered :angel: The cap was fine though.
Ordered a Lucas rotor button from Karcraft on Friday and it was delivered to my door on Monday. That's pretty good. Just standard mail too.
Fitted it and test drove it. Still pretty warm here in Brisbane. Idled fine. Drove fine on petrol and on LPG. Switched it off at the shops and restarted it 10mins later or so and it started up straight away.
Hopefully this is a long term fix.
I rang REPCO and priced an ignition module. They only had a listing for a Fuel Miser unit (CM476) and it cost $169.
I thought you could just buy a generic Bosch 5 pin unit but he said there was no such thing.
Just checked the packet the Bosch part came in and it said 'Made in the UK'.Quote:

LPG is very harsh on the HT system as it requires more 'ooomph' to make the fuel burn. On top of that, the V8 is quite fussy about the quality of HT components...
So, I'd suggest you invest in the best quality HT leads you can find as well as a good quality set of spark plugs.

I did another module conversion today, I should remember to take pictures! The module I use is a Bosch BIM024 module, it has 4 terminals and it must be earthed via a good heatsink. I usually pay around $60-80 trade. Also they can be lifted from any Bosch HEI distributor which has the little tin cover next to the cap, e.g Holden VC-VH, Falcon XE-XF. If I get around to taking a pic or 2 tomorrow I might post them up.Quote:

Hi Utemad, did you solve your LPG miss fire issue. I have a 1997 Disco that this has just started happening to as well. Runs OK on petrol, but miss fires when warmed up on gas. I have rebuilt the gas convertor, replaced the filter. New plugs, ignition module and coil. leads are about 1 year old. I'm sure it is an ignition issue. What did you find?
Yes my misfire was fixed by using the Lucas rotor button. Worth every cent.
If you ever get any more trouble pm bee-utey and ask for his ignition amp and coil mod it worked wonders for me
