replacement, tighten up the linkage at this same spot so that the marks are properly aligned.

5. Having done the above, when you restart the unit the stroke of the new motor should be the same as the

old one, thus the combustion set up should be the same and not need adjustment if it was burning

correctly before.

6. If time permits, check for combustion values noted in Section XXII to ensure proper combustion.

XXV. MISCELLANEOUS NOTES

• If the flue gets black check the high and low fire O

. If these are okay check the selected air fuel ratio curve

selection.

• Check the O
