An adjustable high speed needle valve kit is now available for use in place of the fixed high speed jet on 1963 - 3 h.p. engines. This kit provides a means for accurately adjusting fuel flow in the high speed carburetion system on engines being used in HIGHER ALTITUDES. Reports indicate that in some cases, optimum performance is not being achieved at higher altitudes from 3 h.p. engines equipped with fixed high speed jets.

It will be necessary to remove the lower motor cover and control panel when installing this kit. Readjustment also requires removal of lower cover and control panel, since there is no opening in the control panel through which to insert a screwdriver when making adjustment. The necessity of having to remove the lower cover and control panel for adjustment in addition to there being no external knobs connected to this adjustable needle, however, will minimize customer "readjustment" which frequently proves to be a source of trouble.
Installation is quite simple and instructions are supplied with the kit.
Order this part only from your Parts Distributor. The standard 32% dealer accessory discount applies.
