WITHOUT VACUUM CONNECTION
For big carburetors. The older GX340 engines have larger carburetors installed. Here this isolator is needed.This isolator is standard on the GX390K1, UT, UT1. Does not fit with the current UT2 motor!
Valve guide for inlet valve GX270 to 390.
NOTE: These are "undersize" valve guides. The valve guides must be reamed after insertion to the dimension of the valve!In addition, the valve seat must always be reworked when valve guides have been replaced.
