Hi i have a short wheel based patrol (81) with a 350 chevrolet engine that runs on stright gas (LPG) i have just replaced the manifold gasket and now it has a misfire and will not rev up as it feels like it is starved for gas so i turned up the gas and it has worked a bit and it will now rev but still has the misfire and i am stuck with high revs, so i have turned the gas back .I tryed to tune it but no good still, so i moved onto the spark next. the dizzy was fine, leads were fine, valves where next, but all are moving fine the manafold has no leaks (good old wd 40). can anyone help me i have tried all i can, does anyone know/think what i should do from here. That would be awesome thanks.

I have a 1981 Patrol MQ SWB (p40 engine) with a 4 speed gear box. I want to replace it with a 5 speed gear box. Which model patrol gear box after 1981 can I use.


As long as the cannibalized vehicle has the same engine the gear boxes will interchange. You can also talk to an auto/truck salvage yard, they has cross reference software that can give you more exact information.

A short wheel based vehicle would be the last vehicle I would be towing load of up to 2 tons with. It has the capability to do what you want HOWEVER it does not have the wheel base length to give directional stability when towing. What does that mean ? If you get into a situation where the trailer starts to steer the towing vehicle ( horse moves around and shifts the load position) the distance between the front and back wheels is too short and the towing vehicle will loose control easily.

1985 5.7L Chevy G30 engine problem


do you shut the propane off before turning on the gas ? try turning the propane off and start the MH on gas .. The mixture of the two is whats causing the problem .. Also you need to run it on gas frequently to keep the carb wet so it wont dry up .. it might be already dried up if you run it on propane alot . might be needin a kit in it.. thanks and holler if you need more Jerry

Try adjusting your air/fuel mixture screws. Turn them all the way in and turn them back out 1 and a half turns. This will base line you. Double check for vacuum leaks at the carb. and intake. Spray some WD 40 along the intake where it meets the heads and see if your engine idle changes. If it does, replace you intake gaskets with a good set. Replace carb. mounting gasket. Check for any unplugged vacuum ports. Once you're able to idle it down to 1000 rpm's, turn your mixture screws in until the engine stumbles and turn screws back out until the engine achieves the highest rpm and turn in again only at a 40 rpm drop.
