Hi Brian I will try as you said but was wondering the old original carb I guess would vapour lock and that is why the is a vapour return line to the tank but now that I am using the Mikuni carb is that line even needed? Should I just cap off the end of the pump and the tank and just run the single f...

Also just found this in my manual, so the top spigot do I just cap it off along with the ( vapour return line) at the tank?

So after lots of searching I found this on a go cart site, does this look correct? So the centre of the face of the pump is my pulse hose and the fitting on the top I would use that as a return back to my fuel tank?

So I have a JD300 and am about to use a Yamaha 300 carb and the fuel pump that was given to me with the carb but am not sure how to run all the hoses. Plus I see lots of pics of my fuel pump but none with 2 vacuum spigot. Also the spigot on the top of the carb is that a vent or a overflow? Thanks

Awesome thanks again Brian

sorry I meant to say sheave alignment I say somewhere that a 400 is 9/32 and a 500 is 1/4 but nothing on a 300 thanks

Hi there

Anyone got pics or instructions on how to align my drive belt on my 1977 JD300 I down loaded the manual and I have looked and looked and it does not seem to be in there.

Thanks

Thanks will do

I see some say to use non resistor plugs and caps also use 7mm steel core wire? Anyone maybe have a plug number or a cap number for me to use? Thanks

Hi there just wanted to ask which NGK caps should I buy to replace the old ones and what coil wire is to be used? I know on motorcycles with electronic ign you need to use a certain cap and wire but being this is points does it matter? Thanks

Thanks guys I had a spare motor and had a look at that one and yes the wire was broke so I replaced the whole unit.

sorry a John Deere 300 K2952ax Thanks

Went to remove my condensers and found this wire which looks like it has broken off , I think.
Should this be connected to the green wire?
Not sure if you guys can zoom into the pic.
Thanks]

Anyone ever use the SPI LP01017 and the LP01037 on their JD? Want to replace the points and condenser and ordered these but before I install just wanted to ask reviews on them.
Thanks

No problem
