Just thought I'd let ya'll know.
The Poulan 33 conversion kit from CH is EXACT match for the 42cc as well.

I haven't fully re-assembled my 42 yet...but the bracket and bolt patterns for the 33-42 are the same....IT WORKS!

If anyone happens to talks to the guys at CH, let them know it works.

PS. The CH machined parts are beautiful too. Both flywheel and prop hub have notches to slide a wrench right on them for tightening....smooth!

High Flights All!
