Hi,
Can you explain the nature of your starting problem? I have an LPG converted ls400 that has a starting problem, I wonder if its the same thing. After leaving it overnight, I turn the key and it fires well, climbs quickly to maybe 1000 rpm, then drops to zero. It tends to do this 2 or 3 times, and then on the 3rd or 4th attempt in quick succession, it climbs to 1000, drops to nearly zero, but just catches itself and climbs to idle at about 600rpm.
Touching the accelerator as I turn the key solves this, but obviously this shouldn't be necessary.
I was wondering if 600rpm was a little slow for a cold idle. Do you think my engine is attempting a 'warm' start, even when its cold? Or do you think it has worn valves like yours? It doesn't have flashlube; I better get that fitted.
Many thanks,
Rob
