Howdy gents
I know this is technically more of a weedeater but I've got a pole saw that I found in the ditch.
It's a ht 131 stihl.
First one I've seen that has Stihl's so called 4 mix engine which is kinda confusing.
Wouldn't run for more than a few seconds. Tore the carb apart to find all the gaskets to be stiff so I put a carb kit in it. What bothers me is I dont understand this spring loaded button and extra tube that runs to the bottom of the crank case. I have to assume this is the impulse line because it ties in to the pump side of the carb?
What's that spring for?
I removed the limiters from the high and low settings because that's what I do with all my two strokes
The saw started and runs decent on the high side (limited coil b/c leaning up the high did nothing) gonna have to tune it in the wood.
Problem is as soon as I let off the throttle from starting it would die. I played with the low and idle but no such luck because it never restarted for me.
I wrote down the base settings before tearing the carb apart
The high was 3 turns out (seems very rich but I know nothing on these 4 mixers)
Low was 1 3/4 turns out
I cannot get the saw to restart but I noticed after cranking on the pull rope for a while I had gas in the air filter box. Is the carb flooding or would this be a tank vent issue?
(Separate hose running from fuel tank to the filter housing)
Thanks
