no power 225hp

[tropic]

Hi, my 225hp 1994 V6 loss power for no reason, its no overheating, the fuel primer its new and lines, filters etc... also its hard to start, and when goes from foward to neutral the engine stops. Them its hard to start again and not suport the idle speed. ah the stator its new too.

Re: no power 225hp

Have you checked the plugs and spark? The carberator may also be clogged. If the engine does start can you rev the idle w/o problems?

Re: no power 225hp

Sorry, the plugs and the sparks are new. The carburators have new kits (all 6). What its clogged?full of gas?

Re: no power 225hp

Lets define the issue a little more. Does the motor lose power when cruising or only at low idle and / or going into neutral? If the motor only has problems going into and in neutral I'd look at the neutral sfaety switch adjustment.

What spark plugs are you using?

When you installed new carb kits, did you soak the carbs?

do compression test

Re: no power 225hp

Sounds like some cyl's aren't firing. Spark, Air , Fuel.....
I'm just a regular guy but I'd be checking spark first then compression while the plugs are out. how's your fuel? Is it fresh? Got a filter /water separator? Tank vent is open. Bulb's not flat.

What have you done so far to trouble shoot?

Re: no power 225hp

It sound like when the carbs were rebuilt, the jets were mixxed up. Verify your jets are correct.

Re: no power 225hp

Thanks for the replys, yes the carbs are clean (for a OMC tecnichian) the compression its 90min --- 110 max
the spark plugs are champion (sorry i dont have the number here) whit no electrode you know that spark plug.
I think its something wrong in the carbs
the engine its too hot when its a 4000 rpm or more the water pump its all new the tstas are new. This engines may work whitout termostast (here the water its no cool at all) thanks again,
Carlos

Re: no power 225hp

I would take a look at those cylinder walls with that 20# difference.

Re: no power 225hp

Dont take out the thermostats.They are important for the function of those engines. Your problem is elsewhere.Unless they came out with a new spark plug.That doesnt sound right.I cant recall the number,hopefully someone else will correct me.You say your gettig hot.Why do you think this,is the alarm going off,or do you have a temp.guage.
