Starter Handle difficult to pull:.
1. Remove the starter cover. Does the starter operate smoothly? If Remove the yes, reinstall the cover and continue with 2, if no repair starter.
2. Is the saw equipped with a decompression valve? Yes continue, no proceed with 3.
· Leave the ignition off, set the valve and pull the starter.
· Pull gently to release the valve. Is there a difference in the effort required?
· If yes continue with 3, if no repair or replace the decompression valve.
3. Was this saw perhaps operated in a lean condition (metal transfer from the piston to cylinder wall)? This may be caused by many things including but not limited to; leaky intake connections at the engine or carburetor; leaky crankcase seals; or running on gasoline containing no 2-cycle oil.
· Remove the spark plug wire and plug. Remove the muffler, hold a light at the plug hole and inspect the cylinder through the exhaust port. Is it smooth and shiny or does it appear speckled with dull gray spots or smears?
· Pull the starter slowly, inspect the piston as it rises and falls. Is it a dull gray without scratches and gouges?
· Hold the light at the exhaust port and look through the spark plug hole, inspect the cylinder above the exhaust port. Is it shiny and smooth or speckled with gray spots or smears?
Any spots or smears on the cylinder or deep scratches and gouges in the piston indicate the saw was operated in a lean condition. Repair of this on a home owner quality saw often exceeds replacement cost. A repair estimate by an independent saw shop should be considered.
4. The last likely possibility is the saw has jumped timing. This problem or any not discussed is usually beyond the ability of the operator to repair. Please take it to a good local saw seller/mechanic for a written diagnosis before authorizing any repair. HTH

Causes for excessive fuel consumption in caterpillar D398 Engine


V12 twin turbo with 2x 6cylinder injector pumps.

Excessive fuel consumption can be ...
fuel leak on to the ground.. Obvious
fuel leak into sump via fuel pump body... Check sump oil
worn piston rings... Grey Smoke
glazed cylinder walls...smoke
burnt valves... Need compressin test
faulty turbo(s)... Sound, check manifold pressures
blocked exhaust line/muffler... Smoke black
faulty thermostat so motor doesn't get up to temperature, what is motor temperature ? ... Smoke black
lack of oil, wrong grade of oil for temperature
scavenge fuel line from injectors blocked or not returning to tank
faulty injector(s) causing poor fuel spray
faulty injector(s) bleeding fuel into cylinders... Smoke black
faulty injector pump balance
faulty injector pump timing
faulty coupling between injector pumps, even can be one 180deg out of timing
bad diesel fuel

Are there mechanical losses in motor load ? Alternator fault ? or gearbox fault prop fault ?

What is the exhaust colour ? Black or grey ?
What are the inlet manifold pressures ?
Using a thermometer ( IR if available ) what are the cylinder head or exhaust manifold temperatures ? This may isolate problem to one or more cylinders.

If you can supply more information I may be able to help track down the problem.

What has gone wrong?


No compression? You checked this how? With no compressin, this means there is no closure going on in the engine. You might have a broken valve (s); a hole in the piston; blown head gasket; or other problem; or a combination of problems. If there is NO compression, I would start by emoving the heads and having a look. It may not be economical to fix, rather, if this requires engine tear down, you might want to replace the engine or the entire machine.

Automatic compressin releases are connected to the starter circuit. As long as you hold the starter button down the compression releases will be open. Check the push rod adjustment if they are too tight it will cause the symptoms your discribing.
