Hello, Im here because I have a volkswagen jetta


No one can help on a car with 150,000 miles

You need about $500.00 worth of testing, to see
if is worth keeping the motor mechanically

People get rid of vehicles for a reason & your not
told why.

Start with a cylinder contribution test, followed by
a cylinder leak down test

If the valves are no good,rebuild the entire motor

1997 exc 250 dies at about half throtle just had a complete rebuild


Seeing as how you have had the engine rebuilt, I would start with the carburetor. It could be that the float is not functioning properly, or that you have a dirty jet. It could also be the firing system, and you may want to check that out.

Just bought new pump. My old one lasted for 12 years. New one is 4 months old and recently started to make a loud whine or screeching noise when operating. It works fine but is very loud. I have trouble...


Most likely the bearings on the motor are going out. 4 months is way too soon, but it is possible you got a lemon. Unfortunately I wouldn't expect the new one to last 12 years. It's possible but unlikely. You should however get at least a few years. If the shaft seal on the motor shaft between the impeller and seal plate failed then water can drip back along shaft and get into motor bearings. This will cause motor bearings to fail. Even if this is not the case the motor bearings can fail even though it is rare to do so within first year. I would contact the place you bought the pump from, or whoever installed it. It should have at least a one year warranty. If for whatever reason this motor is not covered under warranty and you have to replace it, I would consider rebuilding it. Normally I don't care for rebuilds, but if the motor is truly only 4 months old then rebuilding it would be a good option.

New alternator fail


If it was rebuilt, could be it was just not a complete rebuild. Some remans are just fixed and cleaned up. Some are completely gone through and good as new. You should have a warranty. Most good remans come with a lifetime warranty or at least one replacement as long as you own the car..

2005 Mercury 50hp 2-stroke outboard motor very sluggish when accelerating, stalled twice when trying to exceed 50% throttle capacity. Last time I used my boat was about two months ago, so I don't think bad...


The carberator is gravity fed and there is propbably gunk in it, when you give it more throttle, it needs more gas but can't get it. Then a build up of gas in the float bowl occurs and nothing works right. It has happened to me and its aggravating, do a complete rebuild on the carb or just replace it and you will be happier quicker.

Hope this helps, Coachtheune

Motor starts, but no electricity...NEW


Make sure the motor is turning the alternator--check the coupling device between them. Is there a circuit breaker on the alternator--reset it? Plug a lamp or something into a socket. If it works, the voltmeter may be in trouble. If still nothing, an inspection of the interior of the alternator is required. If the engine is off, there is no danger of getting shocked. Look for broken wiring anywhere.
