Am in process of rebuilding 2 bbl. Mercarb on 1984 2.5 120hp. Having 2 issues and need advice.
Two needles in kit, spring loaded and no spring...spring style in carb on disassembly.....Manual seems to indicate that the non-spring is a later and preferred style....as in carb may already have been converted to new style. (don't have exact wording here but you get the idea)
Is the non-spring style the way to go?
After getting the varnish off the old plastic float have found it to be cracked. Sierra has a replacement BRASS float.....seems that I have read here that the plastic and ethanol based fuels are not "friendly" and that the brass may be a better material for use.
The issue is that the shape of the 2 floats are quite different and the manual specifies the float setting referenced to a point on the float....is there a way to compensate and use the brass float? or are there instructions for this in the package with the brass float?
As always all help is appreciated......
