Mcculloch chainsaw will not start. Fuel line problems.

[@barchetta7559]

brand new last summer. started it with a small amount of fuel let it run out. now it wont run more than 5 sec. I use pre mixed fuel in a can. THANK YOU!

[@HomeGaragechannel]

I see two possibilities, either the fuel filter is clogged somehow or something strange happened inside the carb because the primer bulb staying collapsed.

[@onesadtech]

This little series is saving my mental health right now! 😂👌 Thank you so much for this! Just picked up a little "Power Mac 145" with a cracked primer bulb... replaced the bulb no problem, but the priming line from the fuel tank cracked off (more like split in 5 places) when re-installing, then I start digging in and check the other lines, the fuel tank to carb line literally fell to pieces between my fingers... I spent another 20-30 minutes trying to figure out how to remove the fuel tank, the trigger setup fell out and apart... anyway, this appears to be the exact same saw, just a different name, so this video is perfect! Thank you!!

[@HomeGaragechannel]

no problem and thank you One Sad Tech

Thanks for providing excellent videos. I have the same model with a cracked primer bulb, this video along with Part 2 video give me the confidence to tackle the repair. I like that you put all parts back together between videos, that way parts don't disappear.

[@icin4d]

I have this same saw. If you look on the back side of the primer bulb, next to the short nipple, mine says "in." That should go to the tank.

[@HomeGaragechannel]

Yes you are absolutely correct.

[@briangafford920]

I have the exact same chainsaw which I bought brand new some years back and it has the same cs 38 em model on the sticker with the side cover having ms1435. I'm not sure why they did that but that's the original side cover for yours.

[@HomeGaragechannel]

I do believe the side cover isn't original. Parts for these saws are almost non existent so you have to rob other parts from a different saw

[@briangafford920]

@@HomeGaragechannel I neglected to thank you for your videos as my chainsaw has been sitting for many years in my garage after I only used for the first 2 years after I bought it new. You can imagine sitting for so long the primer bulb and fuel lines had all dried up. The primer bulb cracked into pieces at the first touch and the fuel lines broke with the slightest movement.. I was able to get a repair kit on ebay and your videos enabled me to successfully replace the deteriorated parts. Thanks so much

Same here.Very strange.Its a great saw.Im replacing the oil pump and all the oil and fuel lines in mine. Hope I can get it back together,it was very difficult to take apart.The flywheel was stamped Aug.2000

it's what we called the 'Mike Jones rule' in mainframe computers... " Don't assume it is a complicated problem. It's probably something simple or stupid... ". A pinched line is simple and obvious!

[@barchetta7559]

good video. my saw won't keep running. the primer ball stays collapsed when pushed in. saw starts when I pour gas into carb, but only runs about 5 seconds. any help is welcome. it's a new saw ran once.thanks

[@captaintruth3219]

Nobody replaced the cover. I have the exact same saw except mine is called a MS1635 Instead of 1435 if you look at the model on top, you’ll notice it says 38 cc but on the side it says 35 cc apparently McCullough before they went out of business decided to play games with the model numbers. I believe they are all 38 cc did you ever get yours running?

[@HomeGaragechannel]

thank you for the information, and yes in the second part of the video, I get it running.

[@gearjunkies2193]

I have the same saw that was gifted to me. For the oil:fuel mixture, do measure it out exactly? Or does a cap full of oil work for a full tank of gas?

[@HomeGaragechannel]

I would suggest measuring it out

[@MegaYangman]

Have the same model from a yard sale. Unfortunately even after putting fuel into the carburetor, it does not start. So it probably has a blown motor I assume.

[@HomeGaragechannel]

Thanks for the comment. Please put some gas in the carb throat and try it again. If it doesn't start check for spark. Hope it works for you

[@Falcon-vu5qp]

Just pull the muffler off and look inside at the piston and cylinder wall. If it looks good and not marred to hell check spark plug. If both of the two look good but it isn't running check the fuel and fuel lines. If at that point it runs but like shit its most likely a carb thing. Small engines only need compression spark and fuel to run. I fixed a really old mac 3200 in a few hours paying $14 on a new spark plug and fuel lines from ace plus some carb cleaner. But yeah before you buy any piece of equipment always see if you can at least pull the spark plug to check the cylinder walls and piston and if they are real nice ask to pull the muffler to check the side of the piston and its rings. The only thing that cannot be fixed for cheap is compression. Hope this helps.

[@jonnysnipes3123]

MegaYangman most likely someone was fooling around with the carb L And H so as long as it’s got compression and spark you will just have to tune it. You’ll know if your piston is scored from your exhaust blowing out a good amount of oil due to the extra amounts of fuel being forced into the cylinder through the score cracks and not being burned off so if you see that take the exhaust off immediately and check the piston for scrapes and scratches

[@turkeydog9148]

If you ever have that saw idle but not rev, make sure the muffler isn't full of fuel.. Don't leave it idle for long periods.

[@HomeGaragechannel]

Thank you for the tip I appreciate it

[@petermawko1378]

I've got a mcculloch chainsaw as well that has the covers not matching up. The side cover says its a MS1636NAV yet the top cover says its a MS42C. I even found a parts chainsaw with the same mismatched model# as mine. Be nice if sone light could be shed on this cuz finding parts is not easy for my trying to fix up mine.

They don't make parts for these saws anymore so parts are a huge hassle. Thanks for the comment

@@HomeGaragechannel got one today same as yours just like that. Says cs 38 and on side 1432. I am sure it was cheaper to use different side covers.

[@ronviebke4098]

In the saw that's featured in the video, It has a 14 inch bar, and 35cc engine. So the MS1435 is the correct cover. (I have an MS1432. And it's a 32cc.)

[@HomeGaragechannel]

sure, either the carburetor is having problems delivering enough fuel to cold start, or the engine is worn to a point where it's hard for it to kick off like it used to. I would do a compression test to determine a wear issue.

[@haroldfearing7363]

Good video. I looked in the fuel tank of my old MAC 3200 and I can see the fuel line is broken into a couple parts. Where do you suggest I get the proper size/type fuel line and fuel filter for my chain saw?
