At least that is the case with my 2-cycle Toro.Snow thrower shave plates and skid shoes are subject to wear and damage. Incidently, it is not necessarily bad for the surging as long as under load the surging stops. It sounds like you want to increase tension.Ĭareful with your "wiring of the throttle" such that you don't over-rev. ![]() ![]() In your case, the float of the throttle implies there is not enough resistance in each direction to stabilize the throttle. #Honda snowblower parts hs621 manualYes, bending a tab is what the service manual called for. This was with an air vane style governor with no adjustment. I loosened the tension, in my case by bending a tab and the RPM's stabilized. The spring forced the RPM's higher and ultimately the governor would counter. In my experience, I had too much tension toward wide open throttle where the governor and spring were in contention. I've seen this with two and four strokes. If, by holding the throttle steady by force, the surging stops, then the throttle linkage and spring can cause surging. Does it run well under load with the choke fully open? Can you hold the throttle steady with your finger and see if the surging stops? If it stalls, then it is a mixture problem or some fuel obstruction still. Sounds like you ruled out a carb mixture or clogged jet problem. Can the spring tension on the linkage cause surging?Ĭan the spring tension on the linkage cause surging? This is under the cover of course so not a user accessible control. The snowblower doesn't have a throttle control anyway so the throttle is fixed from the factory, the only way to change throttle position is by manually moving the throttle lever on the carb. But before I do that I'm just going to put some wire on the cam to hold it in place at a set throttle position and see if that does anything. I suppose I should order new springs for the linkage. Is it possible that there isn't enough spring tension? Thus allowing the throttle plate to "float"? If I hold the cam in place the surging stops. ![]() One of the springs seems a little loose and I can see the cam that moves the throttle plate move back and forth when the motor surges. I've no idea what this is supposed to look like now. I think my problem is with the linkage or springs. I took the carb out AGAIN last night to deal with this "once and for all" and cleaned it all out really well. Ok, back again to dig up this old thread. So, is the diagram correct? Does anyone else have this snowblower that can comment? If i am indeed missing this piece can I just improvise something and what would be an appropriate material to use? Also, they don't sell it (part #8 is not in the list). Shows a strainer of some sort but I don't have that. This either came from the gas or could it come from the air intake? Like I said, I'm new to this. #Honda snowblower parts hs621 fullNot sure if it's related, but the float bowl on the carb was full of debris and sediment. This is all new to me but there doesn't seem to be any kind of air filter on this thing. In the meantime, I wanted to ask whether any of the other HS621 owners could comment on the air cleaner on this thing. So, a complete carb dissassembly is in order and I'll be tackling that once the gasket set comes in. I got it to a point where it'll run with the choke almost off but it surges at that point. There are problems with the carb, it only runs with the choke on. I purchased it for my folks so it needs to start easy and work consistently. I recently purchased a used HS621 that wasn't running too good and have begun getting it back to (or trying to) reliable service. ![]()
