Gas converted engine sounds dry and very noisey

Hi I hope someone can help me. Just fitted a second hand gearbox to my recently aquired stage 1. It's gas converted and starts well but is very noisey and sounds "dry" and the revs seems high. I am out of gas so have only run on petrol for a short time, but it does not sound right.
Only found this out as I test drove it to check gearbox tonight. It's too dark now to start looking into it. So I just wondered if any one had any ideas.
Cheers
Chris

The note of the engine generally can be changed with the timing, so that would be my first guess. Check to see if it is correctly set. Also, remember that the timing for gas is more advanced then petrol.

Hi
Thanks for your reply. Just in the process of putting new plugs and leads in. Have topped up carb dash pots with oil and that has helped but think that the engine is not firing on all cylinders. Oh and the altenator has given up the ghost so replacing that.
Cheers
Chris

Sounds like typical landrover stuff

but hey, these cars make you learn all sorts of things. I had an alternator problem which kept on going for about 6 months before figuring it out. Electronic distributors certainly do have some quirks.

Hopefully what you are currently undertaking will sort the engine out.

Just a couple of quick Qs.

Did you run the engine before you fitted the S/H gearbox? If so, did it sound different?

Just to be clear, is it the same sound on both petrol on gas?

A good way to test the ignition side of the engine is to buy some of those things that fit between the spark plug and the spark plug lead (see through plastic widgets that look like the end of the lead); these flash when the spark plugs spark, and this method has the advantage that you can plug them in, start the engine, and see if all eight are sparking and, if not, it will show you the dead one (much preferable to the 'hold the plug to the block' method, which usually results in 'ouch!'). Someone on here will have a name for them, but have a look online.

Oh, and don't get dispirited - this is very important

Not quite, Larry - though one of those would be useful.

Hi
Thanks for the ideas. Dummy my hadn't checked the oil pump!
Primed it and funny enough it sounds a whole lot better

Cheers Chris

Sometimes it can be the simplest things! Glad you got it sorted.
