45mm bore

[Pierce ramsay]

drop the pilot down to the next smallest size with needle clip in the middle

-also check the compression

needle clip? i know that has to do with the float and carb, but not exacally sure how to adjust.. kept main same size? piolet to 45.

how do i adjust the needle clip? is that to do with the carb and float? when the float rises it pushes up the neelde to stop the flow of fuel. am i supose to adjust that? or is the needle the part that goes up and down when you grab the throttle?

Wrong needle. He is talking about the one that stick down thru the slide and meters fuel in the mid range.

what bear said, also until you get it actually started and idling you dont even need a main jet

You might check you plug gap too, and if it is all fouled heat it up a bit with a propane torch or touch it up on a light wire brush. If your cylinder is all full of gas air it out a bit with a air nozzle in the spark plug hole because if the cylinder is above the lower flammable limit, ignition will not happen. Now if the plug is not all wet when you take it out, maybe your having trouble priming the fuel supply. In this case remove your air-filter and choke the carb manually with your hand. Good luck

*One more thing have your checked for spark?

Just change the d*** spark plug. They are cheap and should be changed each spring anyway. Cleaned spark plugs aren't.

[Pierce ramsay]

Yes I have changed the plug. Checked for spark and checked compression all three I believe to be fine, I don't have a compression tester but I put my finger in the spark plug hole and it blew it out with plenty of force. When I open her up there is plenty of fuel in the bore. I will adjust the pilot and see where we go from there. Thanks guys you are all a great help! Oh and I will go adjust the needle

Fingers are great for checking for nose boogers or anal Klingons. Compression is one of the Top Three Things an engine needs to run well. You don't know what yours is. To test cylinder compression, use This.

the low is about 90psi some will say and that is anuff to as you say """ blew it out with plenty of force"""
so your test is not good .. auto zone or other store rent the compression tester out and when you bring then back you get your money back or by it ... but if your compression is 200 its to high and wont run ether so the finger test is not a good way to test..

ok i will see if i cant pick up a compression tester after work. im home right now but wont have time to get one and come back and then test. right now the needle is in the middle with a 45/115 jets. she starts! if i dont touch anything she will rev up pretty high and then come back down and die. now if i start it and then grab the throttle i can rev it up and down but she will still eventually die. i feel that this has somthing to do with the fuel delivery but when i disconect the fuel line fuel flows fine..... confused.

[swimmingfree]

i have not read all this post ..... you shood let it worm up some before you grab the throttle... dose the petcock have a vack line??? if so have you tested the petcock ???

[Pierce ramsay]

yes the petcock does have a vac line but somthing inside the petcock is broken so gas flows freely to the carb the float is the only thing that stops the flow of fuel.

also, now that i am running the 45mm bore i no longer need my old bore my 51mm rumia bore. i have a 51mm jug and head, $50 takes it. do not have piston for it. i have a 50mm piston i bought for it because i thought it was a 5omm bore, if you need a 50mm piston, rings,clips $10 takes that.
not in a real rush to sell, but if you need it. thanks for your help guys.

you shouldnt worry about whether she will rev yet, you need to concentrate on idle. Once you have it idling you can check to see if your pilot needs to be larger or smaller by turning the air/fuel mixture screw. if you have to turn it almost all the way in you need to go one up if you have to turn it past 2 turns out you need the next size smaller. once you have it where it will idle all day without going dead then move to needle jet clip position. As far as the main jet you should at least heat cycle it some before you start running her wide open anyway. Honestly I wouldnt have put a 24 oko on a 45mm bore but hey its your gas money

[Pierce ramsay]

she is running like a champ. 45/115 plan on going up to 45/120 to keep temps down and make sure she is well lubed id rather be too rich than too lean. i had terrible compression at 86 now im up to 124 with the bottom gasket under the jug wasent sealing due to part of it missing.

white smoke, good, bad, doesnt matter? is this due to the oil i have added to gas tank?

[Mystic]

glad to hear it, take it easy on her for a few hundred miles and it should last you a long time
