Hello Everyone,>

I own a 98 Wrangler 6 cyl with stock fuel injection.>

The catalytic converter was just replaced and I'm experiencing> hesitation while driving. It happens most often when the car is still> warming up but other times as well.>

The hesitation occurred before and after the the cat was replaced.>

Any suggestions?>

Thanks,> Dave

Hi ramva,>

I've been tinkering with my bug for a while to get a smooth acceleration.> When gaining speed i feel a lack of power, and higher in the revs it seems > like the the engine can't keep pace (like it won't get enough fuel).>

It started when i changed the stock fuel pump with a brasilian one. Because > of a leak in the filter screen i used a sealant to stop the leak. (not > knowing the fuel would solve the sealant, the stock fuel pump got blocked)>

First i played with the valves; tighter... looser...> Then adjusted the timing... Dwell... Points... All good, ...on idle!!>

Friday i noticed that when accelerating out of a turn or roundabout for that > matter the car almost stalled. I was driving for my sister in law's wedding > so it was pretty bumpy for my passengers. (and nerve wrecking for me!) What > could this be? Just simply a dirty carb? I haven't changed the sparkplugs > jet, could that be a possibility too?>

Any help is appreciated because in february (still a long time to go) it is > gonna be my wedding car and i do want a smooth drive>

Sorry, forgot to mention.> 34 HP industrial engine ('63?) Euro specifications (Swedisch engine)> So more or less stock>

Hey Jim,>

I cleaned out the carb today, lined up the main jet carrier (lining up the > hole of the main jet carrier with the hole in the carb housing by turning > the carrier ccw)> Tightened the solenoid (was hand tight) and re-installed the lot.> When putting back the carb on the inlet manifold i noticed the solenoid was > sitting on the generator. Is this a problem? Anyhow, the car drove perfect > after cleaning the lot but after another drive the lack of power was back as > never before!>

It even backfires when accelerating (80km in third, hughe lack of power at > higher revs) ГЎnd decellerating.> There is a little leak in the excaust due to a bad seal and clamb. This is > from day one though and it ran perfect before so i don't think this is the > reason...>

The latest thing i have done is loosned the valves a little (0,02mm slith > through easily)>

Is my problem still fuel related or will re-adjust the valves, changing the > plugs do the trick? Or is it wondering in the dark?> I must say it dГd run fine for about a half an hour, so it sounds like i'm > in the right direction....>

Could be yet another lump of dirt got stuck in the carb.>

Put 2 gaskets under the carb to raise it up a bit so the> solenoid has room.>

I think I would blow the carb out again as the first step.>

I'm sorry to butt into this conversation (yea right, haha!)>

But did you make a typo there, perhaps you meant to say 0.20mm?>

The proper clearance for aluminum pushrods in a fairly stock engine is > 0.15 not 0.015 !!!>

0.015 would go to ZERO when the engine warms up, and you would get leaks.>

It works the other way with steel pushrods, then the clearance gets bigger > as the wngine gets hotter. It's because they have different thermal > expansion.>
