017 Stihl chainsaw problem

Could be the spark isn't as strong as you think it is. Could be the spark weakens when the unit is warm. Electronic module ignition needs an energetic pull at the best of times to get a strong enough spark for starting and if it is weaker it would be impossible to pull the starter cord fast enough.
Instead of testing the spark with the standard spark plug try using a spare plug with the gap opened to about 1 to 1.5 mm. The atmosphere in the cylinder during compression is much more dense than in open air and a much stronger spark is needed to jump the gap.

If the spark is satisfactory it could be the crankcase compression that is low, perhaps leaking past the crankshaft seals. If the chainsaw is little used and stands idle for longish periods this could be the problem. Seals tend to lose flexibility quicker under those conditions.

My stihl sh 55 blower starts then shuts off

If it is getting smokey exhaust befor stopping it is getting too much fuel. If not smokey it is not getting enough fuel. If smokey first take out the air filter and clean it. If it runs fine your done. If not smokey open the high needle valve (marked with an H) on the the carb a little (no more than a 1/4 turn).

Will a complete engine from a stihl 017 fit into a stihl ms180 chainsaw.

you should be able to get the engine to fit. The 017, ms170 and ms180 are all part of the same family.

Saw has new vent wont run after hot unless i loosen cap

The vent is not working properly or was installed incorrectly, so there is no negative air entering the tank to take up the space of the fuel leaving it for the combustion chamber. Perhaps your tank cap has a vent as well that isn't working.

Hi, you cant go wrong their both stihls. The 021 is a more powerful saw and the 017 is lighter, so it all depends on your intended use. Regards Phil.
