Picked up another MSAA Craftsman line trimmer recently ,they are just a cheaper version of the Echo line trimmer , don't see that many around now so thought I would add some pics to the forum.
This old MSAA was quite easy Norm as it effectively was a scaled down mower carby -although it has a sliding barrel throttle. No diaphragm and tiny one way valves
Had points though - no great hassle though
Newer ones are not so easy
I started it up yesterday arvo - 6-8 months dormant and went 3rd go
The choke plate is the rod ,it has flat sections machined into the rod so when the choke is off the intake is less restricted but yes they are not the normal type of choke butterfly.
Yes that should make them start quicker Tyler , that green Ryobi in the pic had a smaller hole in the filter housing but I was missing the filter cover so I installed an older housing with a larger hole and it now runs a little rough down low.
I have 2 of the green model and one has always started first or second pull - which is nice - the other 3 or 4
Have had issues of the spark shorting out within the plug boot - fixed with some insulation tape
Also have a brand new one in box - got it for about $100 on clearance a couple months ago - its the one bunnings sell with the chainsaw and long pole attachment. Effectively, for the price, I bought the chainsaw attachment and got the engine and extension pole thrown in
I agree Max - those ones don't have a choke plate in the carby - just the rod and another enrichment method
The later ones have a too large hole in the choke plate - I cover half with epoxy and they start easy - otherwise 5-10 pulls
Or get a replacement where the hole is way too small and the trimmer floods on the very first pull. Been there once. Should had to modify a new carburetor but I did to get it work right.
