How much is one of the carbs? How hard to replace? Are they available?
Not the same probably as the RV mounted ones.
The carb on my snowblower was leaking and engine surging. Rebuild kit was $12. The whole new carb with primer, hoses, gaskets, throttle handle, choke knob was $18. Yup replaced it.
My old hand me down generator with Briggs motor I couldn't get a carb for under $150 and even they were limited. I took it apart and fortunately was able to clean it up. Learned from those like Uncle Dave. They all have fuel shutoffs now. I also run some TruFuel or VP Racing through them first, then shut fuel let it run out. Restart 2-3 times as it sits, then drain the bowl. No matter what fuel it will evaporate out of bowl sitting and leave all the junk. Old snowblower had issue every year (sat in shed in sun). Shop finally said We love helping you but all we do is clean out your red Stabil every time". Told me to do as above and no issues since. I still go there for other services, parts, 2 stroke and VP ethanol free. Hard to find an honest place, I try to support those that I do.
It was the RV unit - I had it in a toy hauler.
I think it was about 150 last time I bought one, there was no rebuild kit when I looked.
