ExLimeyBasher Posted September 4, 2014 Share Posted September 4, 2014 Yes that is your low speed needle, and it looks to be set flush. Quote Link to comment Share on other sites More sharing options...
mikmoo Posted September 5, 2014 Author Share Posted September 5, 2014 Its seems to be running way too rich at low speed. Really boggy. And soon as I start it the car starts moving on its own. Fine at top speed. Quote Link to comment Share on other sites More sharing options...
ajlovering Posted September 5, 2014 Share Posted September 5, 2014 It doesnt look like the low speed needle. The low speed needle is on the slide or barrel. This is the middle needle that controls the balance and transition point from the low end to the high end. The low end is on the other side Set this flush and leave it. Almost all tuning problems are people setting the low end too rich and the high end too lean Cheers Quote Link to comment Share on other sites More sharing options...

The motor used in the colt 15 was the Force 15 pro, go to the ofna website for full details of this engine. Quote Link to comment Share on other sites More sharing options...

ajlovering Posted September 5, 2014 Share Posted September 5, 2014 Although they call it the low end needle it is in fact the needle that positions the high end needle and when it comes in on throttle open. Most other engines have a screw in the end of the barrel to adjust its position with respect to the high end needle and will keep its position when the throttle opens. This is the proper way to adjust the low end. Quote Link to comment Share on other sites More sharing options...
