A: Bummer dude! I got tired of the slowpoke dial up myself, and now that my new computer is up and running, I'm getting Starband satellite 2 way internet for $70 a month (it piggybacks on my current TV satellite, which was bought with this in mind a year ago!) I figured out the cost ($30 for extra phone line, $20 a month ISP and $25 a month for Webtv) and figure $5 a month more for up to 500KPS is worth it!

It's really windy out there and has been raining like crazy... but the real news was posted on the local station: The snow level looks like it could be low enough that we should consider the possibility of some hilltop snow in the lowlands Monday and Tuesday. We'll watch that and keep you updated through the weekend. :) thankfully the wj has quadradrive... otherwise these street tires would be a big problem... the odd size 245/70R16s I'm sure finding tires would be an expensive experience... - --------------------------------------------------------------------------------------- http://www.WAGONEERS.com/ Snohomish, WA - where Jeeps don't rust, they mold... jesus, don't leave life without him, please! - -------------------------------------------------------------------------------------------- ------------------------------ Date: Sat, 01 Dec 2001 22:05:27 -0800 From: Kevin Pekarek Subject: Re: fsj: jeep weather.... > thankfully the wj has quadradrive... otherwise these street tires > would be a big problem... the odd size 245/70R16s I'm sure > finding tires would be an expensive experience... Heh. good luck. All I've seen that size are foo-foo suv tires and heavy duty truck highway rib tires. You'll probably have to look at either 235/75R16 (!) or getting a set of 15" rims if you want something non-highway that won't mess with your speedo too badly. I'd love to be corrected here.

I wonder if the XJ rims would fit the WJ... maybe they went to the 16" rim so they could fit brakes that actually work. :) My XJ had marginal brakes... I've been down the speedo adjustment route after changing tire sizes and gear ratios... not fun. Have a couple of speedo gears sitting on my bench right now. :) Will have to adjust my speedo setup in the J10. Decided to "trade" the NP219 for an NP242. Need to head up to the Jeep wrecking yard in BC to get the same year xfr case to mate to the AW4 I bought up there already... ('96 is a 23 spline input shaft). Then I'll need to do the SYE on it. Guess that runs around $280 or so... Someone on the WJ list pointed out that Michelin does have the LTX ATs in a 16" size that will keep the overall diameter the same. They're narrower though... but that's fine, better wet road traction and better mileage... john At 10:05 PM 12/1/01 -0800, Kevin Pekarek wrote: > > thankfully the wj has quadradrive... otherwise these street tires > > would be a big problem... the odd size 245/70R16s I'm sure > > finding tires would be an expensive experience... > >Heh. good luck.

I figured the worse too... :) The cylinders are numbered from front to rear: 1-3-5-7 on the left bank and 2-4-6-8 on the right bank with the firing order 1-8-4-3-6-5-7-2. (this applies to the 304, 360 and 401 engines). You didn't mention whether it has a 2v or 4v carb. The letter code N is the 2v, P is the 4v. For an Automatic the timing is supposed to be 8 deg BTC (range 6 to 10 deg btc is ok) 700 rpm (600-800 ok) Standard plug RN12Y 0.033 - 0.037 gap alternate plug N12Y If the timing is too far advanced, or even too far retarded, or if a couple of the wires are switched it'll back fire through the carb... ALSO, (unlikely scenarios follow) if the distributor is off one tooth, or the timing chain slipped, or the camshaft key has slipped a bit... those things could do it too. HOWEVER, unless something traumatic has happened, or you just got this thing and it's never run before, I wouldn't go down that route until you check the firing order and timing. If it was running before you tuned it, it's real easy to get the wires switched. I'm very careful to switch only ONE wire at a time... of course this only works if it was running before you got it and the previous owner didn't screw it up. :) That's what happened to me. I assumed the plug wires were right, so when I replaced them one by one I didn't check the order... couldn't figure out why it had no power and was backfiring... I assumed the worst... finally got around to checking the wires and that fixed it. :) Usually this stuff is simple. ALWAYS check the simple stuff before panicking. Don't let some mechanic sell you a rebuild because you had a bad vacuum line either. :) I'd also go through all the vacuum connections, replacing old hoses and vacuum lines, ONE LINE AT A TIME. Also tighten down the intake manifold bolts. hope this helps. john - --------------------------------------------------------------------------------------- http://www.WAGONEERS.com/ Snohomish, WA - where Jeeps don't rust, they mold... jesus, don't leave life without him, please! - -------------------------------------------------------------------------------------------- ------------------------------ End of fsj-digest V1 #1511 **************************
