OutdoorKing Repair Forum Forums Repairs and Maintenance Questions on Engines Questions On Briggs & Stratton Engines Picked up a Masport 400 with a Quantum choke start

MF, the red one actually does have double ball bearing wheels as do at least the 2nd from right. the others have single bearing with rear bush wheels.

The scrawny blade carrier does nothing for power in thick grass - the lack of flywheel effect is marked. you also only have 2 vacuum producing blade lips as opposed to 4.
over thick leaves and tall thinner grass you won't notice and they are a fine choice for most people, but they dont shine in thick grass.

The tornado PT 19s did actually come out with a skinnier disc - they dont run as smooth but still hard to bog out.

If I had time during my yearly lawn reno, i would put a quantum with quadcut next to a quantum with quickcut, victa pt w 4 blade next to skinny 2 blade disc bar.

Ok, as a regular bread and butter mower, I wouldn't mind it. I should be able to fit a quad blade carrier to it later. This would be my mower for life if I got it.

If it were a mower for life you were looking for MF, I would spend the extra $100 and get a lawn marshall mulch and catch. Same thing but with a 159cc cast iron liner motor. Plenty of power and longer engine life.

As you say, you can always swap the disc out later if you found it low on guts.

I have one of these 159cc autochoke loncins on a 19in honda hru19 and can't fault it
Only complaints would be that you can no longer get them down to 1700rpm idle due to lean (and sealed) mixture setting, 2100 is min, and they stumble a bit at idle when cold as the air actuated choke pull off valve doesn't pull the choke off enough for the first 30 seconds

the 123cc and 139cc loncins are a nice motor as well

Why have they dropped the innovative smart flap that allowed it to be a side throw?
Where are they sold? I looked it up and found the specs here.

MF, any masport dealer can order them in - most would have one in stock as they are popular

Don't know why they dropped the smartchute, they were handy

thankfully they have dropped the chipperchute - they were bloody useless

Only thing, if I bought one, I'd want to preserve it and use my 20 clunkers instead!
I think the mulch function was considered the replacement of the smart flap and not considered worth adding to the price.
I had saved a smart flap off a mower I wrecked but disposed of it. May have been worth saving.

Realistically, there is no point of a smart chute for most of us - we probably have utility mowers anyway haha. I have seen so many of them crack near the spring and across the top.

I agree, no point in buying a new mower, I would rather sink the 550 into a top of the range whipper snipper or blower

That's the thing, in first use, that pristine paint finish underneath is damaged that instant you use it. The paint above doesn't take much longer.
550 for a day of joy only for your heart to sink and lapse into depression.
