The new Sears Weedwacker 31 cc 2 stroke would not run at full throttle , right out of the box. Neither was the line head stationary at idle. The old faithful Ryobi 790R had stopped after 10 years. Was it the coil? Below are two handy tools made from "floor sweepings" which solved my...

I have looked into ways to add a dashboard overheat warning light. This is for air cooled tractor heads. Any interest?:anyone:

IMO the oil sloshing around in the air cooled engine pan should run from 212F to 250F, but can still lubricate at well above that, say out to 320F. The additives start disappearing at the high temps, and around 390F oil will vaporize and ignite (flash). The term "breakdown" is undefined, but...

WHY WORRY HOW HOT Air cooled heads do not remain at sump oil temperatures. According to experts their heat can rapidly increase and surpass the oil temp when doing hard work (power demand, high ambient temp, lean mixture -and/or combos). Oil coolers do not alleviate this inherent weakness...

Ever wonder how hot your sump oil or head(s) are? Maybe you should unless you're content with the short life predicted for air cooled tractors. A useful technology widely used in industry is the "K" type thermocouple. Sounds too technical? It's self powered , very accurate, and cheap (for...

After 10 trouble free years trusty, powerful trimmer friend began to make a little noise and loose some RPM. Opened the darling and entered into an new adventure. I f anyone is interested I located some parts places online, got burned by one, defeated a "no tamper" screw and ruined a perfectly...

Today is 93 F ambient, 1800 ft. Mowing dry short grass on medium grade. No bagger system today. Grass straight out chute. Tractor has oil cooler and fan. With fan on average oil temp 270F climbing very slowly to 285F. This happened twice in 1-1/2 hours. At 285F pulled into shade until oil...

Feel free to ask questions about the referenced thread. We know that some things are not as clear as we think they are. No question too basic. No question is dumb. This message is especially for DIY'ers new to grinding. Maybe a better explanation or PIC s could help. I looked today in...

The most I know (apparently not enough) about red sorrel (aka sheep sorrel) is that you should try to kill it in early spring, and that a different spray is reuired in summer. It rains so much here in spring you do not have 2 days with out moisture so normally effective "crossbow" cannot be...

BACKGROUND: In another thread I wondered again about blade balancing after sharpening. No need here to balance was ever indicated with the Craftsman defined "bolt" method. I had not seen a blade sharpener so started from scratch (well this is not exactly new). The bearing blade balancer...

TWO WAY TOOL: This tool works on my Craftsman DYT 4000 - 24 HP Intek. The sketch can be revised to fit your mower. Originally developed to help pull the flywhweel (100 ft lbs), it morphed into a blade removal aid. The red head is off a bent T post. If the SK is hard to read I'll scan it. Let...

Unbalanced grinders are frustrating and unusable. My pedestal grinder sometimes "walks" when a new wheel is put on due to severe vibration.If your grinder vibrates check the wheel concentricity with a pointer held on the tool holder (screwdriver tip, pencil , anything). Rotate the wheel by...

If enough demand I might do a pic tutorial on how I sharpen. It's sure to stir everyone up. Well...?

Hello tractor survivors. My craftsman ytd 4000 24 hp shed its sump bolts this week. Oil mess , rattling and no idle . Found two retaining bolts completely loose and standing on their heads in front of the oil filter (tightening sequence #4, 8). Was able to start them by hand. Then I backed...

Motoman (newbie) here to tell a tale of woe and redemption in the Cascades of WA. It all started with a new Craftsman 48" /Intek mowing the 1 1/2acres of grass of my new digs. All was fine the first year. Summer of year 2 one cylinder went away. Compression good. Baffled. Finally pulled right...

Hi grass people, Against my better judgement I bought a home with 1 1/2 acres of grass about 7 years ago, and innocently bought a Craftsman YTD 4000 48" lawn tractor. As a maintenance freak with cars I thought careful oil changes etc would hold me in good stead... what an education! Anyway I...
