I pulled it out of the barn a couple of weeks ago and I have been trying to get it running again. I got a new battery, changed the spark plug, put fresh gas in it and I do not think it is getting any spark. Is there an in line fuse that might be bad? If so, where? It seems like it is something simple I am overlooking. Also, are there any other common areas I should check? I thought I would ask before I really start tearing things part. Thanks for the help.

Any thoughts? Open to any ideas Thanks! [Reply]  [No Email]

" I get spark, then loose it" makes me wonder if the ignition switch is good and that all connections between the battery and the coil then on to the distributer are clean and making good contact.

"The fuse is located on lead wire which connects ignition-light switch to ammeter and can be found attached behind a metal clip located at rear of battery on back of instrument panel. If ignition or lights fail, check this fuse. If fuses continue to burn out, check wiring for short circuits. It is important to use a 20 ampere fuse. A smaller or larger capacity fuse will not do." Check to make sure you've got spark from both the spark plugs. Operator's manual suggests .025-inch gap for the spark plugs. Operator's manual suggests .022-inch gap for the points. Hope this helps.

It is located behind the ignition switch, you may have to remove the battery to get to it. Also, as previously stated, check or replace the point and condensor making sure that you set the gap correct is also important [Reply]  [No Email]
