1.5 to 2.5 depending on altitude. turn it all the way in and back it out to min first, if wont run smoothly continue out by quarter turns.
make slow adjustments and rev it up several times between adjustments to allow for idle settings and float response.

Timing if upper and lower loopers


if you look closely at the components of the machine they should have small marks on them that line up with each other or marks on the case. most sewing machines are timed this way the marks have to be lined up on both arms and that should work.

Okay. Thanks to Guru, the handlebars were easy to fix. Maybe shouldn't try to ride this thing daily on the road, because now the chain came off. I put it back on, but need to see if there is an easy way...


hi, it sounds to me like the bike has been ridden hard and needs the chain replacing due to it strecthing. on the swing arm at the back is their two bolts sticking out the end of each swing arm their should be one in one side of the swing arm and one in the other side of the swing arm, this is right at the very back of the swing arm.
if you find these then these are the adjusters for the back wheel you then need to loosen the back wheel bolt but dont take it out then adjust these adjusters by the same amount do it in half a turn a time you need to do both the same else the back wheel wont be level keep tightening them in and this will then pull the wheel back and this will tighten the chain if its all ready adjusted fully then the chain is scrap and needs replacing, if you dont have adjusters then the chain needs replacing, it will keep coming off if its slack

you can cause damage to the bike if the chain comes off whilst riding at speed so it may be best to get the chain before you use the bike

How do you adjust the carborator


If this is a late model saw, the adjustment screws have 'D' heads that need a dealer-only 'D' screwdriver. If the screws have slotted heads, then turn both screws CW to stops (lightly), then back each 1-1/2 turns CCW. This is a basic setting, so the engine should start and run. Start the engine and allow to warm up, then pull the throttle full on. Turn H CW until the engine speeds up, but still 4-stroking. When properly adjusted, the engine should 4-stroke, but immediately 2-stroke when cutting. Allow to idle and adjust L CW for fairly smooth running, yet allow the engine to 'follow the throttle'. Adjust idle speed screw to stop the chain from turning, yet the engine keeps running. Hope this helps!

Chainsaw runs only with the choke on. 3yr old but used by a home owner in a very light frequency


Your Idle and Hi speed jets are out of adjustment. If you look near the carborator you should see two, they usually brass screws. There should be markings by them one HI and the other Low for high speed and idel jet adjustment. You adjust the high speed jet for best running and power while sawing, then you adjust low speed for best idle. This needs to be done occasionally. Or take it in to a service shop. It is best if you learn to do it as from time to time it will be needed. When I was in my late teens I was a logger and these adjustments would need to be done 5 or 6 times a day.

How to set carborator adjustment on Poulan Wild Thing 2375?


hello,the starting point for adjustment screws is 2 turns out.turn in til lightly seated so as not to damage them. there are 2 or more style carbs used on saw,some have plastic caps that need to be removed(a small metal screw used as a corkscrew or pry off) or you need a special tool -splined.set high spped til runs good and back off an 1/8-1/4 turn so you dont burn it up. fine tune low spped so it accelerates when trigger squeezed and re check high speed adjustment.single screw is for idle spped-raises or lowers-if chain turns while at idle back off screw.

How to tighten the chain


Loosen the rear axle nut mounting the wheel to the swing arm, then loosen the lock bolt on the top of the chrome adjuster ( left and right adjusters ), then loosen the lock nut on the long adjuster screw. Run the nut about 1/2" down the length of the adjuster screw. Now turn the adjuster screws equally in a clockwise direction to remove the excess slack from the chain. There should be index lines on the swing arm that the single index line on the chrome adjuster is referenced to. Example; If the chrome index line meets up with perhaps the fourth index mark on the swing arm on the left side, the right side should be at the same position. This keeps the wheel in alignment. When the adjustment is finished tighten the axle nut then tighten the adjuster lock nuts and then tighten the lock bolt on top of the chrome adjusters.

Leave some slack in the chain. Mid-chain you should be able to move the chain up and down about one and one half inches. If the chain can be lifted at the rear sprocket it is too loose. Lubricate the chain and the control cables on the bike. What condition are the front and rear sprockets in? The teeth should be bluntly rounded at the tip. If the teeth are sharp at the tip, or getting that way, then the sprockets are way past time to be replaced. Note that a worn sprocket can quickly ruin a new chain.

Please top rate this solution. Thanks!

Drive chain adjustment


To adjust the chain you need to make sure you make the adjustment with the swing arm parallel to the ground, (this is the tightest point in the arc of the swing arm moving rotation), at that point you want to be able to put two finger between the chain and the swing arm at the swing arm pivot bolt. This will insure proper adjustment every time. The best thing to do is have somebody sti on the bike off the stand to make sure the swing arm is at its MAXIMUM arc, otherwise you stand a significant chance of over tightening it and this can and WILL cause SERIOUS damage to your engine. You will rip the output shaft bearings out of the center cases.
You also want too make sure you have proper wheel alignment as well. There are marks on the rear of the swing arm for adjusting the chain, make sure you have the marks on the adjusters in the same location on BOTH sides of the swing arm.
Please let me know if you need further assistance.
Regards,
RSelvy
