I read the post about your last engine having to be replaced. How does the new one compare to your old one power-wise? The old one may have been starved for fuel or running lean leading to the engine malfunction. If the new one runs well and has plenty of power and doesn't smoke, it might be in line with what it's supposed to do

 

I would be curious to know as well if anyone has any input on this topic. I literally just experienced this last night cutting my back yard (4500 sq ft). Fuel consumption seems to be getting worse and worse on my TM. It has always been bad but last night I used a full tank of gas and was still a few passes from finishing before she ran dry. First thing I checked was the carb thinking it was leaking , then checked over fuel filter and lines and didn't come across a leak. I called a local repair shop and they said that it is a common problem with the timemasters and nothing you can really do without replacing the motor .not sure if they were blowing smoke or what not .

 

Hey Harry,

performance wise they are both the same and performed great. even high, somewhat wet grass it leaves almost no clippings when mulching. they stated it was a lack of 'lubrication' on the old engine, but not sure how accurate that is as it had oil.

thanks!

Could be a different blend of fuel, more ethanol in it, or winter vs summer blend, air filter could be plugged, could be a bunch of things.

A buddy and I bought identical new Stihl chainsaws from the same shop at the same time. We were clearing a cedar thicket with 8" diameter cedar trees. I could cut for 15 more minutes than he could. Every tank

 

I was at a crossroads last fall, faced with spending hundreds to repair my old mower or buy a timemaster. I was sooo close to buying the timemaster.

But nearly all the comments I read online mentioned the fuel capacity. Some even said they'd have to stop to fuel up multiple times on the front/back yard.

That was a total deal breaker. I bought repair parts. My current mower probably has 2/3 gal tank that can mow the entire yard twice before refueling.

 

How thick is the oil? Thicker oil uses more fuel. And are you changing oil yearly? Most likely you are, but needs to be asked.

 

regarding the oil changes, I just recently did an initial '5 hour' oil change on it as its a new engine.

could there be any kind of break-in period as its new this year?

thought the filter looked good, but would be easy and cheap enough to swap out.

going to try some tru-fuel soon with it and see if completely non-ethanol makes any difference too
