Say, @DucatiKiller, was just looking through old stuff from when I didn't know anybody on here and just realised it was you who helped me with that carburetor, well, a few weeks ago, lol.
Funny how fast things have changed.
Thanks again, btw. It's still working bent tab and all.
I've got a Walbro WA226 with no hi-speed adjustment screw. Unfortunately, it seems that the issue is in the high-speed jet. Adjusting the low screw can set me up so long as the throttle is at full, but in order to run it at idle, I have to screw the low screw back in a full turn.
How can I go ...
No. The first 12 questions were multiple guess/T&F ... I had to guess at about 1/2 of them. The second section was short written answers. Did okay there. Third section was long written answers. I think I did well there.
When Chevrolet was building the 572 BBC, they'd validate them by putting them on the dyno and running them for 24 hours, varying the throttle between peak torque and peak power ... I can only imagine what that would sound like in the engine room, lol.
Please don't take this wrong ... but do you like rice?
In four stroke engines, spark occurs twice in one complete cycle i.e. at compression TDC and exhaust TDC (In some vehicles, there is a MAP sensor to identify the compression TDC. In such vehicles wasted spark can be avoided). Is there any disadvantage of this wasted spark? Does emission gases get...
I think OP got something wrong here: 4 stroke single cylinder engine? with electronic controlled ignition being widespread there are still wasted sparks?
@DucatiKiller - Nope. Hate grits ... no offense to anyone who loves them. Traditionally, you don't eat grits with cinnamon and sugar ... most commonly with butter, salt, & pepper, I believe.
@Myself - I've not seen too many single cylinder engines with a MAP sensor. In fact, I don't believe a MAP sensor has much to do with anything concerning the identity of where the piston is in its travel up and down the cylinder. And why would it have anything to do with avoiding the wasted spark ignition? The more I read this, the more I see "troll".
@Zaid - I'm not really sure how I'd answer it then. There are a lot of issues/misconceptions on the part of the OP. Would take a lot of work to fix those misconceptions.
@JoErNanO - Too funny! I would like to see @DucatiKiller run as well. He'd be a great mod.
From a theoretical perspective:
Is there any disadvantage of this wasted spark?
Depends on the ignition timing.
If the intake valve is closed when the spark occurs there is no risk of preignition.
If however the intake valve is open enough during wasted spark ignition that air and fuel re...
We'll see ... I haven't gotten the grade back yet, lol!
@Myself - Hey, we all get that way. At least you have a very valid excuse with the newborn! I don't have that considering my youngest just turned 16 ;-)
The Grandkids will run me into the ground, though!
Apart from the mandatory emergency gear that should be in cars (early warning devices, fire extinguishers, visibility vest, first aid kit) what other tools should I get?

No, I am not building a formula one car LOL. I am just busy with my work as a java developer and with my Nissan altima. I am fixing some motor mounts on it. Thanks for asking.
What I really miss at work is that there is no thinking out what algorithm would suit that problem best. Most difficult things are "how to make framework X successfully do thing Y under circumstances Z"
Roadkill is imo one of the best youtube channels (or at least was before all commercial for motortrend on demand)
Last episode of Engine Masters was interesting, but I'd like to know what you can do (cheap) with an old 350 that had like 130hp when new... to get it to at least something decent. I mean getting more than 250hp out of 5.7l must be easy.
I mean they made if like that to reduce consumption of course, but we shouldn't really be punished for that this long time after... GM etc should issue a free undowngrade pack for all their 70's engines :)
@Markus - I've seen a few great episodes lately (Stubby Bob, for one), but I think the real sellout point for Roadkill was when Dodge started sponsoring them. That episode where they thrashed on the two Hellcats and the Viper was absolutely abismal.
@Markus - I'd say "some of the things they do" is expensive. They really didn't start out "expensive" ... but ... um ... agree with you for the most part.
so during the late 70's the Caprice had this: Standard on station wagons and optional on other Caprice models was a 145 hp (108 kW) 2-barrel 305 cu in (5.0 L) version of the Chevy's small-block V8.
"The 5.0 L 305 cu in V8 engine received an electronic spark control and compression was increased from 8.6:1 to 9.5:1. This caused the 305's output to jump to 165 hp (123 kW)"
@Markus - The 305 was completely just a smog motor. It got the car down the road and that was about all you could say for it.
It can be made to make more HP, but even so, it's lackluster compared to what you can do with a 350 or larger ... no replacement for displacement comes to mind.
@anonymous2 - I see you made some changes on my post about the power steering hose. I don't have an issue with anybody cleaning up my posts, as I know I can make mistakes. I would however, caution you in the future to be aware of "local color" or just because someone says something different than the way you'd say it doesn't mean it's actually wrong. Take for instance: tyre v. tire. Both are correct depending on where you are from. You made several of those type changes in my post.
@anonymous2 - And don't get me wrong, I'm not upset about it or anything, but some others may get upset. Just realize there are different ways to spell/say things and the way you aren't used to seeing it doesn't necessarily mean it's wrong.
It is interesting: When having coding problems you just need to formulate them precisely in written, then (most of the time) they solve themselves because you understand the root cause
@anonymous2 @Pᴀᴜʟsᴛᴇʀ2 Generally speaking one shouldn't fix typos that are due to different word spellings. If the post is in US English then leave it in US English.
@anonymous2 It's not a huge issue. I have just been down that hidey hole before, which did nothing good for anyone. Someone had wanted the "tire" tag to be a synonym of "tyre" ... we went round and round about it for a day or so. It wasn't pretty.
Honestly, I didn't even think of alternative spellings, and I ought to have, being Canadian.
If it had been color or neighbor or realize, it would have almost certainly have occurred to me, but pressurized and adapter weren't words that I studied in HS English.
Again, thanks for pointing it out, it was my bad, and I'll definitely try to bear that in mind in the future.
@anonymous2 You would think so. However being old and retired allows them to have a lot of free time on their hands. Combine that with a brand new SE site and that's how you get @Pᴀᴜʟsᴛᴇʀ2 with 70k for example.
it's a 2013 (IIRC) Lucerne (V6/flexfuel) with an aftermarket remote start fitted, and the dealer won't apply the ECU fixes for the CO recall because of said aftermarket remote start
@Pᴀᴜʟsᴛᴇʀ2 okiedokie. side question -- can a non-dealer apply recall fixes, and if so, do you have to pay for that out of pocket or can you get reimbursed for the bill?
@Shalvenay - I don't know the answer to either one of those questions. I'd suggest, yes, you'd have to pay, and no, you'd not get reimbursed ... if a non-dealership can even apply the recall.
I don't get why they won't apply the recall, though ... that's pretty funky.
@Pᴀᴜʟsᴛᴇʀ2 yeah, :/ but oh well, not like I'm in a podunk town with only one GM dealer in it. and yeah, it's pretty strange indeed...an aftermarket remote start shouldn't stop them from fixing a recall for crying out loud
Yes, try at another dealership. If you have the recall letter, just take that in to them. Don't tell them you tried at a different dealership or anything.
