Fat 50 Update

[grover777]

Had a minute to look at motor tonight 1959 Fat 50. FOr those of you who dont know my situation, she starts, howver takes a while to plane, once there she runs pretty much ok, under any load (additional passengers, wont plane). Anyway, I checked my plugs before starting the advice Joe Reeves and others have given me and low and behold, J8C, not J4C as they should have.<br /><br />Could the J8C's be the problem??<br /><br />Thanks!<br />Daron

Wal Mart did not have J4C, either did NAPA so I used J6C per Joe Reeves advice. There was me and another adult and my 5 year old son, hole shot may be a bit better, top end was fine.<br /><br />Should i still get J4Cs or continue to troubleshoot the hole shot with the J6C's??<br /><br />Thanks!<br /><br />Daron

The J4Cs are better for lots of wide-open running, but the J6Cs are best for a lot of slow running.<br /><br />You'll be fine to deal with your tests with the J6Cs, though.
