lpg idle speed problem

[bartlby bus]

i have a romano lpg system fitted to the van 1.9 dg engine it seems to run fine under power but cuts our when idling

how do you adjust the idle speed ? is it easy or is it a trip to the garage?


thanks in advance

you can adjust the idle speed to a certain extent on the idle screw on the carb, but this also adjusts the fools gold idle too.
not sure about your vaporisor settings, do you not have distructions that came with it from install?
talk to the installer /supplier before twiddling, and mark anything to do twiddle before you change anything.........

A typical vaporizer will have two adjustments, a large one (usually spring loaded and plastic) which controls the diaphragm sensitivity and a smaller (usually brass) which bleeds a small amount of lpg via a jet into the system. At idle the vacuum can be erratic and the diaphragm sensitivity control can be adjusted to compensate for this by turning it anti-clockwise. The idle bleed is normally screwed fully clockwise as a starting point and idle set up with the engine warm using the diaphragm sensitivity control. If you are setting the system for cold starting on lpg then the idle bleedscrew will probably need slight adjustment, anti-clockwise a half turn or there abouts. The idle bleed control will allow a small amount of lpg into the induction system irrespective of the diaphragm setting so do not open it too much. Any adjustment should be in very small increments. All adjustments on lpg are clockwise to lean and anti clockwise to enrich. I would strongly advise to get the mixture checked on a CO analyser after any adjustments have been carried out.
