Satsol67 Posted November 20, 2006 Report Posted November 20, 2006 (edited) I was wondering about if I would need to rejet for the winter. I live in the upstate South Carolina are around 1000 above sea level. It doesnt get real cold maybe 30's and 40's in the winter. I'm at 280 mains and from what i could read the pilots are 25. (hard to see going blind I am going to look again today to be sure) If I do need to at what temp should I rejet? And what sizes should I go to? Thanks Ron Edited November 20, 2006 by Satsol67 Quote
dajogejr Posted November 20, 2006 Report Posted November 20, 2006 What temps were you jetted at before? A GENERAL rule of thumb is ever 20 to 25 degree drop in temp is one size larger on the main... Quote
Satsol67 Posted November 21, 2006 Author Report Posted November 21, 2006 The 280's is what it came with and I ran it all summer with those. The summer was in the 80's and high 90's Quote
dajogejr Posted November 21, 2006 Report Posted November 21, 2006 280 sounds about perfect with an airbox and modded lid. I'd say dump a 300 in there for the cold, and you should be ok...but, check the plug to be sure! Quote
Satsol67 Posted November 21, 2006 Author Report Posted November 21, 2006 ok will do. I looked at them last night and they looked good to me both brown but once I get this uneven compression worked out i will do a plug chop. Thanks Ron Quote
dajogejr Posted November 21, 2006 Report Posted November 21, 2006 Trust me, you want to run a tad rich when it comes to cold weather... Quote
Satsol67 Posted November 21, 2006 Author Report Posted November 21, 2006 Mind taking a stab at my uneven compression? I have a thread on it. I did what you said took the cylinders to the shop he told me to get the next size bigger then took them back to have the pistons fitted. Quote
