About P.K. Jones Expertise I can answer most questions about commercial and residential outdoor equipment. I can also help with questions about import atv's, Karts and scooters. I can't help you with generator electrical output however if it's an engine problem, I'm more than happy to help.
I'm in the South, so snowblowers and snowmobiles are outside of my area of knowledge. If it's a question about the engine on a snowblower I can help. But I'm just not familiar with the drive systems for snowblowers.
Experience I own Grand Junction Small Engines and Grandjunctionsmallengines.com, a full service shop and national parts sales site. My shop is an Authorized Repair Center for many brands and we work on equipment from most manufacturers. We are also a dealer and service center for several lines of outdoor sports products such as atv's, utv's and Karts. Personally, I have over 25 years experience working with small engines and outdoor power equipment.
Education/Credentials I've attended many small engine and power equipment factory schools and seminars. I average 100 plus hours annually in update schools and specialized training schools and am current on all brands my shop is authorized to do warranty and factory service on.
Question I have a stihl 028WB chainsaw that sometimes idles but
when I try to accelerate it spits fuel out of the carburetor
throat, smokes heavily out the muffler, rarely reaches full
throttle (and then only for an instant) and then dies.
Sometimes it doesn't do that well and just tries to start.
I've replaced the fuel line, cleaned and rebuilt the carburetor, tried adjusting the carburetor(it didn't help),
replaced the head gasket and replaced the spark plug (it
seemed to work better w/ the wrong plug). The muffler is
oily but clean, I've not replaced the fuel filter or the air
filter but I've tried to run it w/o them (no change),the
compression is 150 psi, and I'm using a 50:1 mix. Also I
would like to know where the best place is to get a stihl
service manual for an 028WB chainsaw. I found one @
tradebit.com that's "supposed" to be for almost every stihl
machine made before 2008, but I wonder if it's true. Thank
you for your help.
Answer You'll probably need to replace the carburetor. First I'd make sure the diaphragm pump in the carb is on right. If it's against the body instead of the gasket being against the body of the carb, then you will have way too much fuel.
As for manuals, your local Stihl dealer might order the manual for your saw. I don't believe that Stihl dealers are supposed to sell service manuals, but you can ask. I'm not familiar with any one-size-fits-all Stihl manuals, I have seperate manuals for many models. They're just paperback manuals of about 50 pages or so. There may be a comprehensive manual but I'm not a Stihl dealer and don't know about all their publications. Thanks, PK.
