Help again with dissy

<< < (2/4) > >>

gtomo2:
Will give it a go tomorrow.
Yea my timing is a pain as it has to be a 12deg before tdc for the lpg to run

drmike:
Start it on petrol - that's what I did with the LPG. Or did you say it was LPG only?

If it is can't you rig up a temporary petrol supply?

Mike

gtomo2:
No it starts on petrol then switches over to lpg. but have it set to just petrol at the moment.

drmike:
I think that I must have misunderstood the problem. I thought you couldn't start it at all - is that you can start it but it won't run on LPG once started?

I got mine started and running well on petrol and then addressed the LPG which does need different timing but I found that I could be at least 20 degrees out on the timing and it would start and sort of run on petrol.

For LPG I decided to tune for maximum vacuum which I could do as I had a vacuum gauge but I was on carbs and had an early form of electronic ignition. I also found that it was a dead loss relying on the timing marks which on mine were hopeless.

Get the leads right then get it started and just keep twiddling the dizzy round until sounds sweet then see where you are!

Mike

gtomo2:
Oh right no it wont start or run on anything just put  a new engine in her and swopped my dissy over and put newer leads on hence why i think my leads are all in the wrong place. :roll: trust me
