Car running fine on petrol but rough on gas

Post by TH850 »

My 2.6 duel fuel rodeo has started playing up abit on gas. It idles fine but once you accelerate it starts to feel like it's bogging down abit until about 2750rpm then it's fine, until you change gear again. Any ideas on what it could be?

Diaphram gauze in the gas converter may have broken / become blocked. Happens fairly regularly on some gas systems. Gas converter has a drain plug as well try opening this up if there's water coming out then its running way too rich either from incorrect tuning or broken diaphram.
