I know you suction tested the fuel feed and changed the filter but twice now I've had insects cause my mower to bog down under load. In both cases I disconnected the fuel line after the filter and because fuel drained out I assumed it was all OK. In one case it would run for an hour and cut 1.5...
I would clean out the fuel tank, the line to the filter and any fuel switch in that path.
Twice I've had bugs get in and mess with the fuel flow. They were big enough to partially block the fuel flow at the exit from the tank and at the switch. Replacing the filter alone may not be enough...
Due to the very high cost of OEM wheels where I live I'm looking to make up some 4 stud hubs and buy wheels and rims for the front of my Toro ride on.
The standard wheel is an 8" rim with 16" diameter 7.5" width tyres. Google says this width tyre ideally needs a 6.0" wide rim. I've been unable...
When you fitted a new clutch a year ago was the bolt tightened up to the correct torque? Did you follow the instructions on conditioning the clutch before use (typically engaging the clutch 5 times at low/mid engine rpm). The makers say they can wear out prematurely if you don't get this right...
In my experience mowers rust and wear well before the engines give out. I've got perfectly good engines on mowers with welded up rusty decks and torn up grass collection bags.
On ride on mowers I've gone through sets of front wheels as when the bearings fail and caused gradual damage to the...
I had an issue with my B&S stopping after after 45 - 60 min running. That turned out to be the remains of insects that had got into the tank. Despite bouncing around over rough ground they would somehow settle out and restrict the outlet. They were bleached the same colour as the tank so v.hard...
On my B&S engine the valve adjustment was quite critical to getting the decompression cam to work. It wasn't working at .008-0.010 but was fine at 0.004.
Took me several goes to get them spot on because the locking seemed to effect the setting quite a bit. Have to recheck after locking.
If...
That really sounds like the decompressor isn't working. I'd have the valve covers off again, recheck valve clearances and look for the little extra lift when turned over by hand.
With the valve cover off turn the engine over by hand. Check the intake valve (I think) for a slight movement just before TDC. If no movement then it looks like broken decompressor. Think it's needs a new camshaft to fix that.
If you need to use the machine sometimes it will start if you...
My understanding is that the B&S has an extra little centrifugal widget that opens a valve at low rpm to decompress the engine to make starting easier. Apparently it only opens the valve a tiny bit, because if the valve gaps are slightly too big it doesn't open it at all and it becomes hard for...
+1 to cleaning out the fuel tank. I had a bizarre problem where the mower would run fine for an hour then start bogging down or stalling. Someone suggested I check the tank. I couldn't see anything in it and anyway my garden is bumpy so the fuel is being shaken up the whole time. I couldn't see...
I had same issue on a B&S. Definitely check the valve clearance is spot on.
Apparently the decompressor only opens the valves a tiny bit so if the valve clearance is slightly out they don't open and the starter can't turn the motor over. Adjusting mine totally fixed the problem.
