Preparing to start a G1 J10

[yamahag1cart]

Hey All -

After picking up a 1979 or 1980 G1 - J10 for free, I am getting ready to try and get her to run. Engine seems to have strong compression. I have just a few questions concerning electrical matters first as I am familiar with the standard fuel, air, spark tests on a combustion engine.

I've put a new spark plug in and plan on dumping the old 2 stroke oil and gas then replacing with fresh... Now for my questions :)

The battery was missing when I got it but the PO said it was just a standard car battery. Can anyone here tell me the recommend group size or number of cold cranking amps required for these old carts?

Also, one of the solenoids is known to be bad, but I was hopeful that the other would be good and could be used for the forward direction? Is this possible and how could I wire or rig it to at least know that it'll go before dealing with buying and wiring a new solenoid?

Thanks in advance for the help!

A group 24 battery. No need for a high cold cranking one. The compression is much lower then a 4 cycle. The solenoids are interchangeable.

As far as the solenoid goes figure out witch one is bad and if forward is bad simply switch the small "signal" wires are this will make forward reverse and reverse forward in the key switch aslo the old style solenoids are no longer available so if you do get it running you will need to convert to the new style http://www.buggiesgonewild.com/gas-y...id-please.html here's how.. if you haven't done it yet I'll pull carb and give it a good cleaning make sure all the jets are clean and blow air through all the passages

I just cleaned and rebuilt my carb. I got the rebuild kit from amazon for around $6, I highly recommend it. Don't forget to clean the fuel pump also, I think there is a sticky on that. Good luck and let's see some pics.

Could you share a link Jetboat? Also posted a ton of photos :)

I think you need to remove the belt so you can move it around. I'm not sure how ad a link from my phone but here is a screen shot of what I ordered and it worked great.Screenshot_2017-11-02-16-31-46.jpg

Thanks for the input everyone! I'll be picking up a battery later today but was super bummed to realize that the replacement keys I ordered for the cart don't fit all the way into the key switch!

Think I have figured out the image hosting and will post pics soon!

I'll have to take a look for the rebuild kit! Wondering if I should re-build the carb or at least clean before seeing if it'll go. More to come soon.

Just figured out how to post photos! Here I go :) Super stoked because with the exception on some lights the thing seems to be completely unmolested.

Below is the serial - Can anyone help decipher if it is a 1979 or 1980 model?

Also there is the old plug I pulled - Does it look pretty normal, or anything to address in the motor?
