    Idle screw PLEASE HELP!

The idle speed is higher now and when I turn the idle screw nothing happens, but when I turn it other way to raise the RPM (just to test if the screw isn't working at all) then it actually works, but problem now is now that the idle is so high...

    Pulsajet idle circuit tuning?

    Short time lurker, 1st time poster. I'm fooling around with a flat head on a Baja frame. After some research it seems the problem I am experiencing may be common with the pulsajet. The engine I believe is a 3hp, I have replaced the carb with a known 4hp as the original was worn at the...

    Mikuni vm22 choke idle speed

    Is there anyway to adjust the choke rpm speed? Mine starts with one pull, dead cold with choke on, however rpms are 3500. Is that what they are supposed to be?

    Tecumseh HS40 (3) carbs giving me fits, they won't idle right.

    I have 3 HS40 engines and 4 Tecumseh carbs. I've taken the carbs apart, soaked them in carb cleaner overnight to no avail. I put in a new carb kit which is just gaskets, o rings and a needle... One carb works better than then the other 3. It will idle and runs well at Wot but sometimes has a...

    Stock Predator Wont Idle

    Was running great on 4th of July week. Parked it for a few weeks, then last weekend it only stayed idling with choke on. If I hit throttle with choke off it ran, but only at high speed close to WOT. I made no adjustments after it was parked. Any ideas?

    Warrior wont idle...

    I have 2 Baja Warriors. One runs like a champ and it is even the most used up of the 2. The better one wouldn't idle without the choke closed about 3/4 of the way. So I pulled the carb off and took it apart expecting to find it full of crud. I was pleasantly surprised to find it very clean. So I...

    Tecumseh H50 Idle Speed

    What is typical idle setpoint for a vintage 1980 H50 (adj. carburetor)? Minibike Service Manual indicates 1800rpm for float-type carbs. This seems extremely high. Just looking for what others have had good luck with.

When I try to put any throttle in it it acts weird and will spit and sputter. Also i installed a stage 1 kit and...
