Hi all,
I've had an 038 AVS Farm Boss with the Bing 48 carb for 5-6 years now, only had occasional use under my ownership as a secondary saw and spent the latter half of that time feeling a bit redundant at the back of the barn after I bought an 066.
I recently decided to dust it off and give it a well-needed rebuild with new barrel and piston - now going very strong - to keep in reserve as a backup saw for bigger jobs should anything go wrong with the 066.
Thing is, it's always had this issue where the in-carb filter keeps blocking up during use; obviously causing the machine to play up, stall and not want to start again until you've dismantled the carb, cleaned it out, and reassembled it. I've done that countless times. But it's a bit of an inconvenience - especially when it can happen multiple times in a day - and doesn't make you look "wasting time tinkering with an unreliable machine" during paid jobs.
The carburetter gasket/membrane set was changed during the saw rebuild; the problem persists nonetheless.
I've never had this issue with any other chainsaw or garden machine, and I run quite a lot of them. First thing I tried was swapping out the fuel filter in the tank, with the theory that perhaps it was letting through some tiny particles that in turn got stuck in the in-carb filter; unfortunately that didn't fix it. I use the same fuel mix from the same gallon can as I do in my other machines, which don't block up, and having already tried two in-tank filters kind of eliminates dirt in the tank from being the source of the blocking particles. The tank itself was thoroughly cleaned out when I rebuilt the saw. More recently upon further inspection I came to the conclusion that dust particles must be coming through the little hole at the top of the carb (pictured) as the chamber underneath is always full of dirt and somehow passing from there to the little filter (not sure how they would get past the gasket), and blocking it.
Surely if this was the case it would be a known issue with this model, however I find no other threads mentioning it. Has anybody else experienced this? Any other ideas as to what the cause and solution may be? Seems a shame to change the carb when it's the original, and working very well when it isn't getting blocked.
