Chainsaw Bogs When on its Side?!?!?

[BurnIt13]

Hello everyone! I have some questions about my chainsaw. From day 1 my Ryobi MY10532 has bogged when cutting on its side. Most inconvenient when trying to fell a tree. Here's the thing....its not bogging because it doesn't have the nuts to keep going, it bogs because it acts like its running out of gas! This happens even if I'm cutting down 1" saplings.

The weird part, this problem doesn't happen when I have a 100% full tank of fuel. As soon as the tank gets below 75% it will bog and die when running on its side. It runs exactly like its out of fuel.

Any ideas?

Possibly a deteriorated fuel hose in the fuel tank that crimps shut when the filter moves into a different position when its on the side?

look inside your fuel tank and move the fuel filter to a better location.

Yep, sounds like your pickup line is sucking air.

Empty the tank and then look inside while laying the saw on its side to make sure the line will flop to the "bottom".

I'd be willing to bet it isn't the fuel line but rather a bad crankshaft seal. If the line checks out ok, check your crank seals. Make sure they are in tight (probably bolts on the bottom of the engine, they can get loose with time). After checking that, soak the crank seals in motor oil (30w works great) and then give it a go. The best/easiest way to do this is to poor some motor oil on the outside of the crankshaft and then also fill the engine with motor oil. Obviously pull the carb and exhaust when you do this. Let it sit overnight, then drain all the oil out, put it back together and give it a go. I've fixed a handful of Poulans this way since actually replacing the seals wouldn't have been worth it.

Hope Your wrong but Great Tip....I Have a old Mac that I will give that a try on....The reason I would say your wrong is the amount of gas is making a difference.

Color me wrong then, I didn't read your entire first post lol. The other guys are almost certainly right if it is only doing it with a lower than full amount of gas in the saw.

Ding,ding ding.

Hey, I admitted I was wrong. Like I said, I didn't read the entire post. Just that it bogs on it's side.

Not faulting you - just showing another confirmation of the likely problem.

Hey I love the fix though........My mac is not worth breaking it down thats for sure!

Joe - I'm glad you posted this and I bet the others are also. I'm often confronted with less thatn perfect saws when traveling in remote areas. This will surely be helpful in the future.

Thanks !

There is a known issue with that model. The original fuel line is too long, which doesn't let the fuel filter/pickup sit where it's supposed to be.

SOLUTION: shorten the fuel line. Some have even added weight (washers) to the line to keep it down.

Thanks guys! I'll give that a try next time I go to use it. I was checking out some of the threads on the arboristsite.com forum and holy crap those guys are nuts! I think I've got the chainsaw bug. Now I'm looking into modifying the muffler and jetting it!

I'll take that as a compliment.

Me too. I'm a member. Heck, I spent about 2 years practically living on that forum when I first got into saws.
