My friends were doing a tip run, so I just asked if there were any mowers in it, bingo one Mustang. A guy did it up and they paid $100, but now it uses too much fuel and is a bit hard to start. I cleaned the G4 , put in a decompressor and put in the outer long spring in the carby. Runs sweet now. It has done little work, plenty of compression and little wear on wheels. Got it on gumtree for $75..... it's old but it's good. cheers jack ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-8869-29588-thabeban_20_aug_2016_004.jpg) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-8869-29589-thabeban_20_aug_2016_005.jpg) I was telling him what I really wanted was a old punt to fit in my trailer....... come this way. Bought this old De Havilland 11ft 3in for $300, so I'm happy. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-8869-29590-thabeban_18_aug_2016_2_008.jpg)

Speedy, it is a 2 stroke, they do that to you, there is a reason they moved to 4 stroke motors for mowers. You now know why it was heading to the tip, the average joe blo can't be bothered with the problems, the fact the missus wants the lawn cut is bad enough for many

The jet in the G4 carb was for a 125cc motor.... I will try another tomorrow. It started today after I put a ne needle valve in. Now it won't start. I will try a different coil as I have a few........ My back is sore from lifting mowers onto my bench....... Gotta get it going and sell it cheap. My neighbor said I'd sell my missus , but I'd never get what I have already invested in her... cheers speedy

Oh now now NormK don't be like that.I think there's other reasons they are changing to four strokes.Possible as they can build them at an 8th of the cost of making two stroke engines. Anyway speedy I just wanted to let you know that your mower isn't a mustang.That particular base wasn't used for the mustang at all.It was more of a Corvette base or a Corsair also some store brands used that base although I think they were still a low arch.I know it has a Mustang cowl on it and I can see it doesn't have a snug fit like it should.Also it is an 80 series full crank engine so I know the carby wouldn't be a G4 it should run an LM carby. Similar but not the same. This is what a 80 series mustang looks like,with that cowl. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-5048-29636-104_0808.jpg) These two model Mustangs ran from 1979 to 1981 (I think).Also they were the first model Mustang after the VC was dropped from the name. And this one is the one that took over in I believe 1982. This one however has been awesomely restored. This mower is one from an ODK menber. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-5048-29634-8570_4.jpg) ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-5048-29635-8571_5.jpg) Just thought I'd let you know more about your mower. Cheers.

Hi Speedy, i'm going to ask a couple of obvious questions before you change the coil. Has it got spark, if not try isolating the kill wires first and make sure you have a known working plug in it. Does the primer prime? Have you checked the piston to see if it's cooked? Cheers, Ted

Hi Blumby, I love 2 strokes, I think they are an amazing motor, it is just the average person who has a couple of hours to mow the lawn and the 2 stroke doesn't want to play ball and they got a bad rap when you got half the lawn cut and couldn't get it started again. I think I have 10 or 12 Victa 2 strokes so I am not anti them

Just a Thing I've found with fixing these carbies is that the fuel bowl needle needs to be the white one, I've found the fluro needle is slightly longer causing the fuel bowl not fill enough. Just a though...
Good fuel/clean air & plug I find are key to easy 2stroke operation
Regards, Paul
Such is life....... Nothing better than a "GreenField" just mowed..

Awesome good to hear we need more collectors of 2 strokes as it won't belong now and they will be a thing of the past.Up the mighty 2 stroke. Also there SuperDooper I have in the past,and I know this might sounds silly. I've even had the needle stick in it's seat.Took me a long time to work that problem out. I've had that in a few carbys now.

Hello Blumbly & Bigted. First Blumbly I was thinking you must have either forgot to take you medication or taken too much, as I used two Mustangs in a mowing business in the 70's, but don't remember all the details.... Your probably right as the guy put this machine together with any parts on hand then sold it. Now bigted, there is a good spark, a new chinese plug from cheap shop. I put the correct jet in for a 160cc engine not a 125 that was in it, and I put a black needle in. It's got a white poppet valve with ABC in, but I remember my old Mustangs had a black poppet valve as I used to clean the carbs every week...... I left the white one in. I dump the kill wires, fill the space with hotglue. I put a new started cord in. Anyway i started ok, mowed the front yard, let it sit for 15 min, and restarted ok. then started it later in the afternoon, it started again, so I'm thinking it will be ok. I want to keep this one for myself. I'll sell my good 4 stroke my mate gave me instead.
thanks speedy Bundy

Sounds like you could be in the winners circle there.For your poppet valve I'll through this up here for you. ![[Linked Image]](https://www.outdoorking-forum.com.au/forum/uploads/usergals/2016/08/full-5048-29669-poppet_valve.jpg) The black poppet valve of which you mentioned were usually fitted to a G4 carby and they had a flat surface where it seating the carby. The white LM version had a ridge that run round there with two openings in the ridge.You can see it in the image above. As far as medication goes I'm always taking more than I should,but hey it keeps me smiling.

I can assure you,it's not.Those bases were never used for Mustangs.The Mustangs at that time were the top of the line and were at a higher price.Those bases where the next models down.
