Chainsaw problems need advice

I have 2 chainsaws. the first is a very old sthil there is plenty of fuel in it but it is only running half way up the fuel line. I have cleaned the carb and fuel lines and all seem to be ok.

Im not sure of the make of the second. It is very hard to pull the starter rope. I removed the sparkplug and it turned over fine. I have not changed the spark plug and im sure its the correct size. I have also remover the exaust but it still will not pull unless I remove the spark plug.

Any help would be welcome Thanks.

Probably a silly question, but are you sure it's the proper plug and not one that's too long?


Measure it with a micrometer; cut it with an ax.

The Chainsaw

Another silly question; Is the safety brake unlocked? It happened to me once or twice.

If it feels exactly the same with the brake on or off, then I would suspect the brake is staying on.

Have you tried to prime the engine with a little gas on the other one to see if it will start?

Might need a kit put in it, the diaphragm may be stiff.

Compression

Im not sure of the make of the second. It is very hard to pull the starter rope. I removed the sparkplug and it turned over fine. I have not changed the spark plug and im sure its the correct size. I have also remover the exaust but it still will not pull unless I remove the spark plug.
What you have is really high compression. Probably greatest when engine is cold. I have a saw which has high compression and I have to stand on the handle when I start the thing. Expecting the rope to break any time. It is a Husky 266 pro.
