I have a Stihl FS85 with an issue. It will start and idle but will not accelerate to WOT. The carb is a Zama C1Q which is also marked with a small 82. There are no other numbers. Installed carb kit and cleaned carb in and out. New hoses and filter. Fresh gas. When squeezing the throttle it...

Thank you Mechanic Mark. Especially for the manual. Figured it out I believe. Plugged fuel filter. I was fairly sure it was a gas cap vent issue but I ran it with cap on tight at WOT and no problems with new filter installed. Thanks again. Knots

Blower starts and runs fine for a couple minutes and then starts to slowly reduce speed with throttle wide open until it quits. Pulling choke will let it run a few seconds longer. Will start again in a few minutes with same end result. Any thoughts about where to start would be greatly...

Engine data for this thread Kawasaki FH580V. Mower is Toro Z400 Z Master Serial 270002174 Engine was running ok when parked after use. When tried to restart, barely ran and no movement on one intake rocker. Pushrods not bent! Whatever happened, happened all at once. If camshaft was wiped, I...

Don’t have all engine data but have a general question. Zero compression on one side and intake pushrod not moving. Suspect wiped camshaft but is there any other possibility like a lifter stuck at the top of its bore, etc.? Thanks, Knots

Many thanks to all that offered helpful comments to my original question. I truly appreciate all your help. Knots

Burnish is the term that both Scag and the clutch maker,Ogura use. The issue is not the definition of “burnish” it is whether or not the well defined burnish procedure should be done on a new factory Scag, Ogura manufactured PTO clutch. That is all I am trying to figure out. I am well aware of...

Thanks sgkent and star tech. The main reason for my question is that the new clutch from Scag (gt-5) has a big brown tag on it that says “DO NOT BURNISH”. Ogura disagrees with that tag. Knots

This is an OEM Ogura clutch from Scag. Knots

Question: Do Ogura replacement PTO clutches need to be burnished before use? This is a Scag Turf Tiger 35 hp Briggs. Tag on clutch from Scag says “do not burnish”. Tech service at Ogura clutch facility says “they absolutely should be burnished”. I told him about the tag with Scag’s name on it...

Scag Turf Tiger Model STT61V-35BVAC-SS Serial. E5400225 Any thing unusual I should look out for when replacing PTO clutch on above mower? Any special tools needed. I am guessing that it might be really tight on shaft. Please advise. Thank you, Knots

ILENGINE, Thanks for the prompt reply. That was the diagnosis I came up with but wanted to hear it from someone that knew what he was talking about. Thanks again, KNOTS

Another question concerning Scag Turf Tiger 35 hp Briggs. What should the amperage draw be when clutch is engaged with meter in series with wires feeding clutch? This one measured 15.24 at engagement. Only connected for an instant as I was afraid of cooking my Fluke 88. Resistance at clutch plug...

ILENGINE, Thank you very much… Knots
