Help diagnosing Briggs and Stratton “Victa” 375 Sprint issue
Hi All,
From my rudimentary understanding I think I know what’s up, but would love some additional thoughts and support.
I bought a Victa 375 Sprint from my mate. He sold it to me very cheap saying “it runs on methylated spirits because it runs rich”.
Took out on face value. Sure enough runs OK on metho. But after sitting for a few weeks it won’t start. Primed it, pulled, spluttered.
So, curious, I pulled off air filter and drained tank to replace with Unleaded 91. Air filter is clean. Tank had some gunk. Certainly came out with some bits and pieces.
Anyway, before replacing or cleaning carbs, decided to add a bit of 91 and run it.
Starts up OK then just barely runs. Very choppy low revs. Sounds like no fuel getting through.
Ran it to mow lawn. After about 5 minutes it really fired up but then spluttered again and died.
So I think I’m confirmed. Gunk in fuel. Carb probably blocked jets.
My next plan is to pull the tank, clean it, and see if I can also take apart carb and clean. Should I just replace the carburetor? Anything else I’m missing?
