in this thread, I want to discuss how 4-cycle atv engines work- what the different types are... how they are set up and which you prefer. To start off, are the cams on ALL atv 4-strokes powered by a cam chain? I know that on say a lawn mower or logsplitter engine, the cam is turned by the tappet, pushrods, and valve rockers. Which is better and why? Chain-driven cams or pushrod-driven cams? Are the pushrods just an old version and everything is transforming to chains or the other way around...or not at all? Just looking for some explanation, history, and downsides/upsides...
Below is a quote from a response to similar question from yesterday:
"Easiest thing to check is trash in the main jet. if it idles fine, then the idle circuit and low speed jet is clear. if it bogs off idle that's when it's transitioning to the main jet."
I will go ahead and open up the carb and check the main jet, but please respond to this post as if the main jet is squeaky clean.
Below is my post:
Only starts and runs on Full chock.
Does not matter what position I have my "mixture" screw. Tried it at zero, 1 turn, 2 turn, up to five turns. Spent a few hours confirming that the position of the mixture screw does not resolve issue.
Runs great at idle and if I slowly engage throttle, it will rev up as expected. But, quick rev up or when I am trying to drive it, it spits and sputters and looses power.
I also use a propane bottle and did not find any obvious leaks, and the vacuum port is hooked to fuel peacock and I also made sure to simply block the port with my finger to see if that would resolve the issue.
New Carb (after market), New Coil, Fresh Gas. No leaks at manifold boot, hot battery. Good gas flow. Runs too good to be a valve issue, or cylinder, great compression.
I can move the choke out a tiny bit, and it will still run, but will still bog down when I try to power it up.
I also have a 250 trail boss Polaris that I require to run at full choke, but it has power at all throttle potions.
I suspect it is running rich as the choke is on, but will not run with it off.
Any details would be appreciated.
Product warning: Lighting products manufactured by Larson Electronics LLC 9419 E US HWY 175, Kemp Tx. 75143
Hi, I’m G. Randel and I have a small business that does boat and motor service and repair and rigging. I also service and repair off road 4 wheelers, lawn equipment and small engines. I have been doing this type of work for over 40 years, so I have accumulated some knowledge about the accessories and products needed to support those things.
I recently installed two high intensity LED lights on the T-top of one of my customers boats. He bought the lights after he had done considerable research and consultation with manufacturers. He wanted to make sure he was getting something that would serve his needs which was to see where he was going at night while underway on the water. He decided on lights manufactured by Larson Electronics out of Kemp, Texas. They were reported to be rugged, weatherproof, waterproof to 3 meters and were warrantied against workmanship or component failure under normal use for 3 years. One light quit working within 10 months, the other is still working after about 16 months. I removed the defective light and sent it back to Larson Electronics for warranty repair or replacement and they denied the warranty claim. Their reason was “failure was due to environmental damage”.
At the time of purchase these lights sold for over #365.00 each and the representative that my customer talked to at Larson Electronics assured him that these lights were well suited for the purpose in which they were going to be used.
So, if you are looking for electronics, as in lighting, for your ATV, SUV. Boat, or any other outdoor application you might want to keep in mind that Larson Electronics LLC
9419 E US HWY 175, Kemp, TX 75143 might not fulfill their warranty claims if you have a problem with their products.
Great sayings by police officers
These 16 Police Comments were taken off actual police car videos around the country:
#16 "You know, stop lights don't come any redder than the one you just went through."
#15 "Relax, the handcuffs are tight because they're new. They'll stretch after you wear them a while."
# 14 "If you take your hands off the car, I'll make your birth certificate a worthless document."
#13 "If you run, you'll only go to jail tired."
#12 "Can you run faster than 1200 feet per second? Because that's the speed of the bullet that'll be chasing you."
#11 "You don't know how fast you were going? I guess that means I can write anything I want to on the ticket, huh?"
#10 "Yes, sir, you can talk to the shift supervisor, but I don't think it will help.
Oh, did I mention that I'm the shift supervisor?"
#9 "Warning?” You want a warning? O.K., I'm warning you not to do that again, or I'll give you another ticket."
#8 "The answer to this last question will determine whether you are drunk or not. Was Mickey Mouse a cat or a dog?"
#7 "Fair? You want me to be fair? Listen, fair is a place where you go to ride on rides, eat cotton candy and corn dogs and step in monkey crap."
#6 "Yeah, we have a quota. Two more tickets and my wife gets a toaster oven."
#5 "In God we trust, all others we run through NCIC."
#4 "How big were those 'Just two beers' you say you had?"
#3 "No sir, we don't have quotas anymore. We use d to, but now we're allowed to write as many tickets as we can."
#2 "I'm glad to hear that Chief (of Police) Hawker is a personal friend of yours. So you know someone who can post your bail."
AND THE WINNER IS...
#1 "You didn't think we give pretty women tickets? You're right, we don't. Sign here."
