so i'm taking the oft repeated advice to service the carb on my recalcitrant jonsereds 535.
Easy access to the diaphragm with one screw without taking the carb out of the saw, but from other threads I've garnered that the actual model # of the carb is going to be on the body near the mixture screws which is obscured without removal. Other than identification, it looks as if I were careful pulling the mixture screws, I could just about flush it out with air and carb cleaner in place.
Haven't found any listing for carbs on Jonsereds models that might help me narrow it down without getting an identification off the carb itself (which I understand is the gold standard). But if I can narrow it down to a couple choices I could order a couple kits and see which one fits, but if the choices are myriad ...
... or, if I'm missing the importance of getting to some part of the carb that is inaccessible while installed for a good cleaning then my next problem is that I'm mystified by the method of attachment of the carb to the cylinder. It would almost seem that the carb is installed the way it is so it can be more regularly accessed, cleaned and serviced without complete removal, which is sensible given the prevalance of carb issues generally, esp. when saws sit. But if I do need to pull the carb, either for identification or service, I've hit another dead end.
It seems that the body of the carb is molded to a rubber boot and that boot is secured on a short horn coming out of the engine but I can't observe a traditional clamp of any sort. There appears to be a wire molded into the boot that just has very short ends emerging that are twisted around each other almost like a bread tie.
Maybe this is actually more robust spring steel than I imagine and I should just take a pair of pliers and untwist and the will snap off each other without breaking off, but I've not run into this system before so any 1st hand experience or cautions appreciated.
thanks,
brian
