Postby storchman40 » Wed Sep 09, 2009 5:51 am

i have an hp vt 21 that ran great on break in the plane crashed in a tree but did not hit the ground the carb was twisted sideways by a limb and bent the needle housing i bought a new needle vale,housing assembly but now the engine will not run correctly and is harder to start and the idle is terrible i have to keep the glow igniter attached i have tried several different plugs(standard long) but makes no difference i also noticed there is a leak behind the head i can see bubbles coming out i assume this is the problem with bad idle and running i ordered new gaskets but am waiting on them to try if any one knows of any othert suggestions it would be greatly appreciated. :cry:

For sure, air leaks to the will wreak havoc on idle and consistent running.
I think you are on the right track. Make sure you loosen and reseat everything, tighten head bolts in cross pattern.
