There isn't anything intrinsically wrong with plastic carburetors. Lawnboy used them for many years and didn't have any problems with them. They have also been used on a large number of small 2-cycle engines (trimmers, blowers, etc) for many years without issue. Additionally, they are not subject to the corrosion problems that are common with metal carburetors using E10.Man as a lover of overkill I would love that kawasaki engine but I think a Toro 21564 would suffice for me. I just dont like a plastic carb.
The problem with the B&S EXi engines are with the camshaft. I think the Briggs has a handle on this but it remains to be seen. FWIW, camshafts are also the problem with current OHC Hondas which has caused them to issue a stop-sale order.
