wolf creak has the kit and so does H&L
Thanks, that's exactly what I'm going to use. After re-gaping to 0.020"That is not the correct Bosch spark plug. WSR6F
I think those may be made in China or Brazil now?
I'm using NGKs more often now. BPMR7A
If I need a carb kit for the "China" carb where would you get it? Doesn't matter, all the same? ebay?Your "made in china" carb looks to have come in a genuine Stihl box and labelling- so it highly likely genuine. Stihl owns a plant in China to supply like items.
Your original is a Tillotson- they came with those, or earlier 038's came with Bing carbs. This is normal- not unusual and they are not marked for Stihl- they got carbs from known carb manufacturers- just like they did with cylinders and pistons.

Tillotson makes carb kit for theirs and Bings. The Bings were on the later 038M. They also have a new manufacture replacement.Are you getting a bit ahead of yourself? Thought it worked well when on the saw?
That carb is the current available Stihl Zama offering for the 038/380/381- C3-S148 so a Zama kit for that carb will be available almost anywhere- Zama RB-167
It does until buried in the wood. Then it surges. I don't have much experience diagnosing/repairing saws. Just thought maybe some of the rubber parts in the carb may need to be replaced. Planing ahead, plus I have other saws to work on too. Knowing where to get the reliable parts is just part of the process.Are you getting a bit ahead of yourself?

I did check the spark plug wire, but I'll check it again.Look over your fuel line well. I've had 038 fuel hoses go bad and you can't see the cracks without taking it loose from the carb and bending it a bit. The cracks being between the ribs on the hose
In my case the saw would miss in the cut almost like an ignition problem.
Also check the ignition lead to the plug. If the AV buffers wear out the wire can get damaged/pinched and give an intermittent short. Had that happen too.
I did check the spark plug wire, but I'll check it again.
The AV buffers were changed when I change the gas tank a couple years ago. I'll still check the wire, thoughAre the AV buffers in good shape? That wire ends up getting pinched between the fueltank/handle assy and the crankcase
Yes the impulse hose can be removed and installed as I described previously. Make sure to remove the air filter cover and top/cylinder cover. You’ll need all the wiggle room you can get.@ballisticdoughnut, can you completely remove the impulse hose by the method you described earlier? Using hemostats and fishing around? Can you replace them too in the same way without anything else?
Thanks. I do see both ground wires and how they function to shut the saw down. I was hoping it would be a quick fix.The wire- you are correct- the break in the insulation and proximity to the rod could allow current to jump the gap- but it needs then for the rod to be able to carry that current to earth/ground to kill the spark.
There should be two wires on an 038 going through the "firewall" of the air box- the black one you show that is the trigger contact- and another (blue from memory) that has an eye connector at each end, one eye goes under the metal tab the switch contacts- held by the screw that holds the metal to the base of the air box- goes up through the same grommet at the top and down to where the top cover bolts to the crankcase- this grounds the switch in the plastic tank models.
Personally I change position of this wire to ground on the AV mount so it does not get forgotten of the top cover is removed.
Impulse line is fitable with the tank insitu- but is not dead simple to do and yes, long hemostats are a big help to get it seated on to the cylinder barb.
I have used AM carb kits- but we do not have E fuel either. If you are not sure about anything or have doubts- use genuine kits.
The main carb parts you are wanting to replace are directly under the cover on either side- but pay attention to both the order they are fitted in and the orientation of them as you replace them.View attachment 1153426View attachment 1153428
next time drop the rear av mounts on the rear and pull down on the handl for acsess to the lower cylinder /impulse hose locationPut everything back together to see if the hoses made a difference. Surprisingly the saw runs great. Either it was the hoses or the wire.
Thanks everyone.
