This 'Echo 2-strok- engine has three intake ports on the cylinder and each port has a designated reed, any one of which if slightly loosing pressure will result in bad performance not easily identified.... Testing all 3 reeds only takes a minute when the carb is off: Use a short piece of 1/2 'hose and draw negative pressure with your mouth through each one of the 1/2" ports, it literally takes a minute to check... There should be ZERO leakage even if a little negative leak it's bad....Check this first and in the repair you'll feel more confident.. Also this 'Echo carburetor is old school with both high and low speed needle valve adjustments for that smooth transition in between High/ low rpm's. Doing these two things is a great foundation for a good diagnoses

We’re do you order chains and tires from

It runs good on high idle could be points or condenser

Good Evening Sir, that is an interesting engine 🤔👍Nice tips on how to torque the bolts for the head gasket 😇👍Again You Are Truly An Expert Sir 👍😇👌Be Well Cheers 🍻🍻

I've got the same spark tester Artie but for some reason I can never really tell when it's sparking! I could see your spark good I see them good Ole Craftsman tools in the bag👍🏾

I think you are right, from the marks on the block it does look like the head was leaking. It does seem to run a lot better now but I guess the popping suggests valves. Running on load for a while could help a lot

An interesting setup with the way the valves are on ether side of the piston. I haven’t seen that before. It does seem better.

Hi Artie, so you say this started after it revved up fast, so could it be something to do with the inner workings of the governor 🤔,or the timing off a fraction

👍🏻👍🏻👋👋

great vid on channel thanks lee

Lol not a std thats good artie dont want a disease tractor. Nice one my friend

Artie I think you solved the biggest issue by replacing the head gasket. It looked blown to me in the video and the block was really sooted up in that area too. I do hear a little flutter in the exhaust every now and then though. Could the points in the magneto be causing that? I know sometimes in the old engines a worn valve guide can cause the exhaust valve to not seat properly sometimes and that can cause a flutter in the exhaust every now and then. It's hard to guess what's going on in an engine from 1956!

You’re getting there Artie. I was told to use oil on the head bolts. You get better torque on the bolts. I do three tightenings. Let’s say it’s 50 ftlb you need. I go to 30, let sit for 10 minutes or so, then to 40, let sit, then to 50. Just an example. Different looking engine than what I’m use too. Sort of a hemi head design. I find a lot of flat head small engines pop out the exhaust. The spark didn’t look right, but seemed to run. Take a break from it Artie. Then go back at it another day. Have a great Thursday Artie. 👍🏻👍🏻👋👋🚜

Good idea to replace those bolts when they get hot they stretch replacing them give you a better torque value

A crazy question did you try a new spark plug?

Sounds like the valves are not seating all the way to me. But I am sure you will figure it out 👍🏻

How's she goin'? Wow Artie, this old Gravely is a mystery for sure eh. That was a good test taking the carb off the good machine though. Now you know it's not a carb problem. When you added the note about 'ignition', I'm thinking you have a half idea what might be wrong!! LOL You're cagey like that Artie!! LOL Take care!!

What a frustrating job! It will be interesting to see what the issue turns out to be.

Nice work brother, lil late on this but ill catch up 😄

It is an interesting but frustrating problem. Great idea to put a known good carb on. It could be valves or head gasket but it may be worth swapping some electrical parts first. It is very handy to have another machine

If it helps, I don’t have a clue but I know you will sort it out

Good day Sir, You Will Find That Problem Sir Since You Are THE BEST GRAVELY REPAIR EXPERT TOP MECHANIC SIR 🧐👍👌Be Well Sir And Keep Up Your OUTSTANDING VIdeos Sir Cheers 🍻🍻

My guess is the timing got out of time when the governor put it to full throttle. Kicking back when you try to start it is not good and an indictor of the timing off. Head scratcher for sure Artie. Take a break from it. 👍🏻👍🏻👋👋 Great video.

The way it’s kicking back on you when you’re trying to start it leads me to think your timing may be off. It looks like it’s trying to fire too early, before the piston is at TDC.

Artuu you’re the best ❤love you cuz ,hope you’re doing well

This is a head scratcher Artie, but you will get there in the end 👍

great vid on channel thanks lee

It sounds like the condenser has a Erratic spark...maybe start their thanks for sharing brother 🙏

Nice one Artie. Warm wishes from Millionaire Paul 👋

great video artie sounds like you had your work cut out for you but you got it running in the end 👍👍

Thanks mate

Head gasket coming up, after all that work its not the carb, patience hey artie

I took off head gasket .Original has paper surround metal around it. Bought new, no metal surround at all. What do you think ?

A real mystery and a great entertaining video Artie. Full watch. Warm wishes from Millionaire Paul 👋

Cool sharing

omg, great video, funny too. loved the part where the hose was fed thru the wrong hole. been there done that with other shit. thanks for putting this video out there.

How's she goin'? This one is eating your lunch Artie. I was thinking maybe poor compression and then near the end of the video you mentioned about checking the compression. That may be worth a check. Keep at it buddy, you'll get to the bottom of it I'm sure!! Take 'er easy!!

Good on Artie. Gremlins. That’s what it is. They sneak around at nite to peoples garages and fool things up on you. I’ve had my share of them. Hehe. Hard to know what goes on Artie. I’ve put machines away at the end of the day, working good, and the next time you use them somethings wrong. I put a tractor in storage years ago. Drove it in. Sat all winter. The next spring it would not start. Took a used plug out of another engine and put it in. Tractor started right up. How does a spark plug go bad, sitting all winter not being used. 🤦🏻‍♂️. It’s a wonder I haven’t pull all my hair out over things like that. Have a great day and weekend Artie. 👋👋👍🏻👍🏻

Take care of dad‘s machine good video Artie

Pretty frustrating job. Now it works, now it doesn’t. A head scratcher for sure.

Lol artie sometimes you just got to throw down the wrench and sleep on it lol

It looks like the identical carb fitted to the some of the Bolens we have with Wisconsin engines and we have lots of problems with them. Great idea to spray brake clean around the gasket to see if it is leaking

Hi Artie, you don't have a dodge fuel filter do you 🤔, it sounds like fuel starvation when on tickover 👍

I think I know what happened here. I just had something similar occur. You had the system open while working on your head gaskets, I had mine open while fixing a rotten hose that comes from the top of the block in that same area. When I got a new section of hose installed it fixed my coolant leak but then I lost heat inside the cab. I flushed like you did a few times and backwards a few times also checked the dash selector as you did here. Still didn't work. Then I wanted to see if it had flow so I opened the line just before the selector or actuator whatever. Turned the truck over but it had no flow. I was worried when you said yours had no water/coolant when you opened it. Mine had very little. I let truck idle for a good while but even when hot the coolant never flowed. I then grabbed the throttle body and rev'd the motor. Water then started to flow with higher rpm. I did that a few times then reconnected the coolant line to the selector valve. When I got back inside the cab the truck had heat again. Seems like that valve just needs to have the system primed/bled at that location. Cheers, this video still helped me dive into the trouble shooting. Thanks again!

Good Morning Sir, You are truly THE BEST GRAVELY REPAIR SPECIALIST SIR 👍👌🧐For me, at the end that engine run fine 🧐👍👍Be Well Sir Cheers 🍻🍻

Grimlin's brother....it happens 😊 great show buddy 👍

Switch to 93% gasoline on my Graverly, car and all powered hand tools. Much better performance and reliability.

Nobody knows what happened overnight Arty, it’s magical. 🤣🤣🤣never never land,, so funny. Leaking like a siv,,, it just got worse so funny but frustrating I’m sure. Brilliant video Sir

Hello brother Artie 😀 fantastic repair buddy 👊

Thank 's A lot of help. The shaft & impeller must be tapered like GRANDPAW's old DRILLBITS.
